Every electronics repair professional and serious hobbyist in India eventually learns the same lesson: a standard screwdriver set from the hardware store is useless for electronics work. A quality precision screwdriver set for electronics repair is one of the first tools you should own — and getting the right one means understanding the different bit types, sizes, and handle designs that matter for phones, tablets, laptops, and PCB assemblies. This guide covers everything you need to make the right choice.
Why Standard Screwdrivers Fail at Electronics Repair
Consumer electronics use screws that are fundamentally different from the hardware you find in furniture, plumbing, and automotive work. The screws in a smartphone are typically 1.2 to 2.5 mm in diameter — too small for any standard screwdriver tip. Worse, manufacturers use specialty screw heads specifically to discourage non-authorised repair.
Using an incorrect or ill-fitting screwdriver on a precision screw causes cam-out (where the tip slips out of the screw head), which strips the soft aluminium or alloy used for electronics screws. A stripped screw in a phone chassis can mean a ₹500–2,000 repair bill at a professional shop — or in severe cases, the component becomes unserviceable.
Precision screwdrivers solve this by providing exact tip sizing with tight tolerances, hardened steel tips to prevent cam-out, and fine control handles for low-torque sensitive applications. The difference between a ₹100 hardware store set and a proper precision set is immediately apparent the first time you open a real device.
Essential Bit Types for Electronics Work
Phillips (PH) — The Most Common
Phillips screws are the most widely used in consumer electronics worldwide. In precision electronics, you will most commonly need PH00 and PH000 sizes. PH0 is standard for slightly larger assemblies. India-manufactured electronics (including local PCB assemblies and Arduino-compatible kits) frequently use PH1 and PH0 screws. A complete set should include PH000, PH00, PH0, and PH1.
Flathead (Slotted)
Less common in modern electronics but still found in older equipment, potentiometers, terminal screw blocks, and some enclosures. You need extremely thin, precise flathead tips — standard hardware store flatheads are too wide and too thick for electronics-gauge screws. Sizes 1.0 mm, 1.5 mm, 2.0 mm, and 2.5 mm cover most cases.
Torx (T)
Torx screws use a 6-pointed star recess. They are common in laptops, Apple products, gaming controllers, and power tools. T4, T5, and T6 are the most common in consumer electronics. T8 and T10 are used in gaming consoles (PS4/PS5, Xbox). T25 and T30 appear in power tools and industrial equipment.
Pentalobe
Apple’s proprietary screw head, used in iPhone, iPad, and MacBook assemblies. Pentalobe screws have 5 lobe points and come in two sizes: P2 (0.8 mm, used in iPhone 4 and later) and P5/P6 (used in MacBook battery screws). No standard screwdriver fits a Pentalobe — you specifically need pentalobe bits. Any serious mobile repair set in India should include these.
Tri-Wing and Tri-Point (Y0, Y1)
Tri-wing (three asymmetric wings) was used in older Nintendo hardware. Tri-point (Y-type, three symmetric points) is used in iPhone 7 and later for Lightning connector screws, AirPods, and Apple Watch. Y0 (0.6 mm) is specific to Apple devices; Y1 (1.2 mm) is used in some Nintendo Switch assemblies.
JIS (Japanese Industrial Standard)
JIS screws look almost identical to Phillips but have slightly different geometry. Using a Phillips driver on a JIS screw causes immediate cam-out and stripping. JIS screws are found in Japanese electronics brands (Sony, Panasonic, Canon cameras), Japanese motorcycles, and older Japanese audio equipment. A set with JIS bits is valuable for anyone repairing Japanese consumer electronics or cameras.
Hex (Allen)
Hex screws are common in laptop hinges, camera tripod mounts, 3D printer assemblies, and some enclosures. H1.5, H2.0, and H2.5 cover most electronics applications.

Handle Design: What Actually Matters
Electronics precision screwdrivers require a fundamentally different handle design from standard screwdrivers. Here is what separates good handles from bad ones:
Rotating Cap (Spin Top)
The most important feature of a precision screwdriver. The top of the handle should rotate freely and independently from the grip section. You press down on the rotating cap with your index finger while turning the grip — this allows precise, low-torque driving without your index finger fighting the rotation. Drivers without a rotating cap make fine screw work frustrating and imprecise.
Knurled or Textured Grip
The grip section needs enough texture to provide torque control when it counts. Smooth chrome handles look professional but are slippery with any amount of hand moisture. Look for knurling or rubberised sections that give you grip without bulk.
Magnetised Bits
Magnetised screwdriver tips let you pick up and position tiny screws (M1.5–M2) on the tip without them falling off. This is indispensable for phone repair where 1.2mm screws are essentially invisible when dropped. Most quality precision sets have magnetised bit holders or magnetised tips.
Tip Fit and Hardness
The tip must fit snugly in the screw recess. A tip that is even 0.1 mm too wide will not fully engage the recess and will cam out. Hardness matters too — soft steel tips deform quickly, requiring replacement. Look for S2 steel or chrome vanadium steel tips, which maintain their geometry through hundreds of screws.

What Should Be in a Good Set?
For electronics repair in India, a well-rounded precision screwdriver set should include:
Minimum (Budget) Set
- Phillips: PH000, PH00, PH0, PH1
- Flathead: 1.0 mm, 2.0 mm
- Torx: T4, T5, T6, T8
- Pentalobe: P2
This minimum set handles most Indian market smartphones (Android), basic laptop work, and Arduino-compatible enclosures.
Comprehensive Set (Recommended)
- All bits from minimum set, plus:
- Pentalobe: P5/P6 (MacBook)
- Tri-point: Y0, Y1 (Apple Lightning and Nintendo)
- Hex: H1.5, H2.0, H2.5
- JIS: J00, J0, J1
- Torx: T10, T15, T25
A 64-bit or 100-bit kit in this range typically costs ₹600–1,500 in India and covers virtually all consumer electronics work you will encounter.
Buying a Precision Screwdriver Set in India
What to Look For on the Label
- S2 steel bits: S2 tool steel is significantly harder than the generic steel in cheap sets. Critical for preventing tip deformation.
- CRV (Chrome Vanadium) handle: For durability of the handle mechanism, not just the bits.
- Bit count: More bits is not always better — a 24-bit set with quality bits beats a 110-bit set with soft bits. Check that the bits you need for your primary use case are included.
- Magnetic bit holder: Non-negotiable for phone work. If the listing does not mention magnetised bits, assume they are not.
Budget Tiers in India
- Under ₹300: Generally soft steel bits that strip quickly. Acceptable as a starter kit for very occasional repair. Replace bits when tips show wear.
- ₹400–1,000: Best value tier. S2 steel bits, rotating caps, adequate selection. iFixit Mako and domestic equivalents fall here. Recommended for regular hobbyists and students.
- ₹1,500–4,000: Professional-grade kits with precision manufacturing, strong magnets, premium packaging, and long-handle options for better torque. Ideal for repair shop professionals.
- ₹5,000+: iFixit Pro Tech Toolkit, Wera precision sets. Over-engineered for most users but justified for full-time professional repair work.

Common Use Cases: Phones, Laptops, Arduino Enclosures
Smartphone Repair (Most Popular in India)
Indian mobile repair is a massive industry, with millions of smartphones repaired every year by small shop owners and DIY enthusiasts. Common requirements by phone brand:
- Samsung: PH000, PH00, T5 (some models)
- Xiaomi/Redmi: PH000, PH00, T3 (some hidden screws)
- OnePlus: PH000, T5
- Apple iPhone: P2 (pentalobe outer screws) + PH000 (internal)
- Realme/Oppo/Vivo: PH000, Y0 (Lightning-style connector screws on some models)
Laptop Repair
Laptop bottom panels use PH1 and PH0 screws most commonly, with T5 and T8 appearing in hinge assemblies and some brands’ bottom panels. M2 hex screws appear in SSD and RAM mounting on modern ultrabooks. A comprehensive set handles all brands available in India — Dell, HP, Lenovo, Acer, Asus.
Arduino and DIY Electronics
PCB standoffs, project box screws, and terminal blocks typically use M3 or M2.5 screws with PH1 or flathead heads. Larger enclosures use M4 PH2. Precision flathead screwdrivers in 2.0 and 2.5 mm are frequently needed for screw terminal blocks on DIN rail enclosures and Arduino shield headers.
Caring for Your Precision Screwdriver Set
- Never use precision screwdrivers for high-torque work: Precision screwdrivers are designed for 1–5 N·cm of torque. Using them on tight mechanical fasteners deforms the tips and destroys the handles.
- Keep bits clean and dry: IPA (isopropyl alcohol) is safe for cleaning screwdriver bits. Avoid acetone, which can attack plastic handles.
- Store in the case: Precision bits stored loose in a drawer get mixed up, lost, and damaged. A dedicated indexed case keeps everything organised and protects the fine tip geometry.
- Re-magnetise when needed: Screwdriver magnetism weakens over time. A simple magnetiser/demagnetiser tool (under ₹100) restores full magnetism to your bits in seconds.
- Replace worn bits: A tip that has been rounded by cam-out will continue to cam out on every subsequent screw. Replace worn bits rather than persisting — new S2 steel replacement bits are inexpensive.

Frequently Asked Questions
What size screwdriver do I need for iPhone repair in India?
You need a P2 pentalobe screwdriver for the two bottom screws (adjacent to the Lightning port), and PH000 Phillips for the internal screws once the display assembly is removed. For iPhone 7 and later, you also need a Y0 tri-point for the screws securing the Lightning connector bracket.
Is there a difference between a precision screwdriver set and a repair toolkit?
A precision screwdriver set focuses on the screwdrivers and bits. A repair toolkit adds opening tools (spudgers, plastic pry tools, suction cups), tweezers, and sometimes a mat and case. For phone and laptop repair, a full toolkit is worth buying — the opening tools are just as important as the screwdrivers.
Can I use any Phillips screwdriver for electronics?
No. Consumer electronics use PH000 and PH00 sizes which require a screwdriver tip with an outer diameter of 1.5 mm and 2.0 mm respectively. Standard Phillips screwdrivers start at PH1 and are far too large, causing immediate stripping of the screw head.
What is cam-out and how do I prevent it?
Cam-out is when a screwdriver tip slips out of the screw recess under torque, damaging both the tip and the screw head. To prevent it: use the correct size bit, apply firm downward pressure while turning, and never use worn or damaged bits. A magnetised tip also helps hold the bit in the recess.
Are electric precision screwdrivers worth it for repair work in India?
For occasional repair, a manual precision set is sufficient. For repair shop environments where you open multiple devices daily, an electric precision screwdriver (like the Xiaomi Wiha or similar) pays for itself in time saved and reduced hand fatigue. Ensure the model you buy has adjustable torque to prevent overtightening tiny M1.2 and M1.5 screws.
