## Long description

The Wiha 284 screwdriver bit is manufactured from chromium-vanadium steel and designed to deliver consistent strength and wear resistance. It features a 4 mm hexagonal shank and a 150 mm overall length, providing extended reach for fastening tasks while remaining lightweight at approximately 33 g. The precision-machined tip and balanced profile make the bit suitable for handheld drivers and powered screwdrivers that accept hex shanks.
Advantages
The chromium-vanadium steel construction offers high tensile strength and improved wear resistance compared with standard tool steels. The 4 mm hexagonal shank ensures secure engagement in hex chucks and quick-change holders, reducing cam-out and slippage. At 150 mm length the bit provides easier access to recessed or hard-to-reach fasteners while the low weight supports comfortable prolonged use. Precision tip geometry supports accurate fit to fastener heads, lowering the risk of damage to screws.
Suitable for
 Assembly and disassembly of machinery and equipment with hex-compatible fasteners
 Electrical and electronics work where extended reach is required
 Automotive maintenance for interior and bodywork fasteners
 DIY home repairs and furniture assembly
Key specifications
 Material: chromium-vanadium steel
 Shank shape: hexagonal
 Shank size: 4 mm
 Overall length: 150 mm
 Weight: approximately 33 g
 Tip: precision-machined
How to use
Insert the 4 mm hex shank into a compatible driver or quick-change adapter until it seats securely. For manual use, pair with a hex bit holder or a handle designed for hex bits; for powered drivers, ensure the chuck or holder supports the shank profile. Apply steady, controlled torque appropriate to the fastener material and size to avoid over-tightening. After use, inspect the tip for deformation and store the bit in a protective bit case to maintain tip geometry.
Usage recommendations
Use the bit only with drivers and holders rated for hex shanks; avoid impact use unless the bit and holder are specifically rated for impact applications. Keep the bit clean and free of burrs; replace when tip wear affects fit. For precision work, verify fit before applying torque and use correct torque settings where applicable.
