Screwdriver Bit Wiha 284

The Wiha 284 screwdriver bit is a precision tool engineered for controlled fastening tasks. With a 150 mm length, a hexagonal shank and a lightweight 30 g construction, it combines reach and balance for tasks requiring accuracy. The bit set includes Torx T6 and T8 tips and features a through-hardened CVM steel blade with a titanium silver finish and lasered size markings for clear identification.

Advantages

Through-hardened CVM steel provides durability and wear resistance while the hexagonal shank ensures secure engagement with bit holders or drivers. The 150 mm length gives added reach in recessed or confined areas, and lasered output sizes on a titanium silver surface allow quick tip identification. The included T6 and T8 Torx tips support precise torque transfer for small fasteners.

Key specifications

How to use

Insert the hexagonal shank into a compatible bit holder, driver or ratchet. Select the required Torx tip (T6 or T8) and engage it firmly with the screw head. Apply steady axial pressure and turn the driver to fasten or loosen the screw, keeping alignment to avoid cam-out. After use, store the bit in a designated holder to protect the tip and preserve the lasered markings.

Recommendations

Use the Wiha 284 bit for precision fastening tasks and avoid applying excessive bending forces. For best results, match the Torx tip size exactly to the screw head and use appropriate torque settings on powered drivers to prevent damage to the fastener or bit.
