Wiha 284 Screwdriver Bit

The Wiha 284 screwdriver bit is a precision tool made from high-quality CVM steel with through hardening. It has a titanium silver finish and lasered size markings for clear identification. With Torx tips T7 and T9, a 150 mm overall length and a hexagonal shank, the bit is designed for secure fitting and consistent performance in detail work.

Advantages

Manufactured from through-hardened CVM steel for strength and wear resistance. Titanium silver surface treatment improves corrosion resistance and reduces glare. Lasered output sizes ensure easy, long-lasting identification. Hexagonal shank guarantees a reliable fit in compatible drivers and holders while the slim 150 mm length provides reach for confined spaces without sacrificing control.

How to use

Insert the hexagonal shank into a compatible bit holder or driver until it seats securely. Select the appropriate Torx tip (T7 or T9) for the fastener, apply steady axial pressure and turn the driver with controlled torque to avoid cam-out or damage. Use the 150 mm length to access recessed fasteners while maintaining visibility of the lasered size markings for quick identification.

Recommendations

For best longevity, clean the bit after use and store it dry. Avoid exposing the bit to excessive torque beyond the recommended limits of the fastener and driver. Replace the bit if signs of wear or deformation appear to maintain precise fit and prevent damage to fasteners.
