Wiha 284 Screwdriver Bit 2 pcs

The Wiha 284 screwdriver bit set contains two Pozidriv bits manufactured from high-quality chromium-vanadium (CrV) steel with through hardening and a titanium-silver finish. Each bit is 150 mm long, has a hexagonal shank for secure holding in compatible bit holders or screwdrivers, and features laser-etched size markings for quick identification.

Advantages

The bits combine durable CrV steel construction and through hardening for improved wear resistance. The titanium-silver surface and laser-etched output sizes increase corrosion resistance and make sizes easy to read. The hexagonal shank ensures reliable retention in standard 1/4" bit holders and screwdrivers, while the 150 mm length provides extended reach for recessed or hard-to-access screws.

Suitable for

• Automotive and mechanical assembly tasks requiring Pozidriv fasteners
• Electrical and electronic repairs where precise screw engagement is needed
• Professional workshop use and home DIY projects
• Working in recessed or deep-set screw locations

How to use

Select the appropriate Pozidriv bit and insert the hexagonal shank into a compatible bit holder, screwdriver handle, or power tool adapter. Ensure the bit is seated firmly, align the tip with the screw head, and apply steady pressure while turning. Use the full length of the bit to reach recessed screws and avoid excessive side load to prevent tip wear.

Recommendations

Inspect bits before use and replace any that show significant wear or rounding. Store in a dry place to maintain the titanium-silver finish and prevent corrosion. For prolonged life, avoid using the bits on damaged or improperly sized screws.
