A screwdriver set is a collection of tools designed to drive or remove screws. Sets can range from basic flathead and Phillips drivers to highly specialized precision and impact-rated drivers.

🪛 🧰​ By Tip Type

1. Flathead (Slotted) – Single flat blade. Common but outdated in many applications.
2. Phillips (cross-head) – X-shaped. Standard for general use.
3. Pozidriv – Improved Phillips with extra grip.
4. Torx (Star) – Star-shaped. Found in electronics, cars, and appliances.
5. Hex (Allen) – Six-sided. Common in furniture and bicycles.
6. Robertson (Square) – Square tip. Popular in North America, especially woodworking.
7. Tri-Wing / Tri-Point – Used in electronics (e.g., game consoles).
8. Security Bits – Variants with tamper-resistant designs (e.g., pin-in-Torx).

🧩 By Handle Type

• Standard Screwdrivers – Fixed handle and shaft.
• Precision Screwdrivers – Small, for electronics, watches, eyeglasses.
• Ratcheting Screwdrivers – Gear-driven handle lets you turn without repositioning.
• Insulated Screwdrivers – For electrical work, rated up to 1000V.
• Offset or Right-Angle – For tight or awkward spaces.
• Stubby Screwdrivers – Short handle for cramped areas.
• Torque Screwdrivers – Adjustable torque control for delicate fasteners.

🛠️ Key Components✨
1. Handle

• Material: Plastic, rubberized grip, composite.
• Features: Ergonomic design, anti-slip, rotating cap (in precision models).

✨ 2. Shaft (Shank)

• Material: Typically chrome vanadium steel or stainless steel.
• Length: Varies by need (short for tight spots, long for reach).
• Insulated or not for electrical safety.

✨ 3. Tip/Blade

• Hardened and magnetized tips improve grip on screws.
• Black oxide or coated tips resist corrosion and wear.

Bit SetsSome screwdriver sets include interchangeable bits rather than fixed tips. These are versatile and space-saving.
🔩 Common Bit Types:

• Flat, Phillips, Torx, Hex, Pozidriv, Square, Triangle, Spanner, Clutch, Security Torx.
• Material: High-speed steel (HSS), S2 steel, titanium-coated, black oxide.

​✅ Features to Look For

• Magnetic Tips – Hold screws in place.
• Color-coded Handles – Quick identification.
• Storage Case or Organizer – Keeps tools tidy and portable.
• Ratchet Mechanism – Speeds up work.
• Torque Control – Avoids over-tightening.

🧪 Materials & Durability

• Shafts: Chrome Vanadium Steel (Cr-V), Chrome-Molybdenum (Cr-Mo), Stainless Steel.
• Handles: Polypropylene (PP), Thermoplastic Rubber (TPR), Cellulose Acetate.
• Tips: Hardened steel, black oxide coated, precision ground.

🧼 Care & Maintenance

• Keep clean and dry; wipe after use.
• Avoid using screwdrivers as prybars.
• Store in a dry place, ideally in a case.
• Magnetized tips may need re-magnetizing over time.
• Occasionally oil moving parts (ratchets or pivots).

📏 Standards & Specifications

• ISO and DIN standards for tip size and hardness.
• VDE Certified tools for electrical safety (up to 1000V).
• ANSI Standards in the US.

🛒  Buying Tips

• Match the set to your needs: General purpose, electronics, automotive, electrical, etc.
• Check tip variety and sizes.
• Ensure handles are comfortable and grippy.
• Prefer magnetized, heat-treated tips.
• Portability & storage are important for mobile work.
• Avoid very cheap sets—they often strip or wear out quickly.

Specialized Sets

• Electronics Repair Sets: Tiny Torx, Tri-wing, pentalobe, anti-static tools.
  
• Automotive Sets: Long shafts, flexible shafts, Torx and Hex bits.
  
• Electrician Sets: VDE insulated, color-coded.
  
• DIY/Home Repair Kits: Mixed drivers, common tips, often include pliers or testers.
