Flawless screwing – Types of screwdrivers and bits, materials, and maintenance
Screwing is a basic yet essential task in every professional environment—whether it's assembly, maintenance, or production. High-quality results don’t come only from experience and precision, but also from using the right screwdrivers and bits, made from durable materials and maintained properly.
In this guide, you’ll learn:
- the key differences between screwdriver bits,
- how materials and coatings affect performance,
- and how to reduce wear and slippage with proper use and care.
Most common BIT types – The difference that matters
Knowing the difference between bit types is essential for precise, safe, and long-lasting work:
- PH (Phillips): Cross-shaped bit with rounded edges. Common in general use, but prone to cam-out.
- PZ (Pozidriv): An enhanced PH with additional ribs for better grip—ideal for woodworking and assembly.
- SL (Slotted): Flat bit, less common today due to lower grip and ease of slippage.
- Torx (TX): Star-shaped bit offering excellent grip and high torque resistance—popular in automotive and industrial use.
- Hex (Allen): Six-sided bit used for internal screw heads, common in machinery and electronics.
The wrong bit type or size can damage both the screw and the tool, reduce torque, and waste time.
Screwdrivers and bits: Material quality and protective coatings
Professional tools must withstand intense use. That’s why it's essential to use bits made from high-grade steel (e.g. S2 steel) and protected with durable coatings:
- TiN (Titanium Nitride): Increases wear resistance and extends bit life.
- Black Oxide: Protects against corrosion and improves grip.
- Chrome or Nickel Plating: Enhances hardness and rust resistance.
At POPAR, we offer a wide range of professional bits and sets featuring premium coatings and industrial-grade materials. Explore our bit and screwdriver sets here and find the right fit for your work.
Tips to prevent wear and slippage
- Always use the correct bit type and size.
- Clean bits regularly - dirt reduces grip.
- Replace bits once visibly worn - dull edges lead to slippage.
- Use quality screwdrivers or machines with torque control.
High-quality bits save time, reduce material damage, and improve overall workflow.
