Screwdriver Bit Wiha 284 2 pc(s)

Wiha 284 screwdriver bit set contains two 150 mm hexagonal bits made from high-quality chromium-vanadium (CVM) steel with through hardening. The bits feature a titanium-silver finish and lasered size markings for quick identification. One end of each bit has a ball profile that permits working at angles up to 25°, while the hexagonal shank provides a secure fit in compatible screwdrivers and holders. Each bit is lightweight (34 g total) and designed for general fastening tasks requiring extended reach and reliable torque transfer.

Advantages

High-quality CVM steel with through hardening gives improved wear resistance and durability. Titanium-silver coating and lasered output sizes make identification and corrosion resistance better. Hexagonal shank ensures secure engagement with drivers to reduce slipping. Ball end allows angled operation up to 25°, increasing accessibility in confined or awkward positions. The 150 mm length offers extended reach compared with standard bits while remaining lightweight for ease of handling.

Suitable for

• Assembly and disassembly of hex-socket fasteners in furniture and equipment
• Maintenance and repair tasks in confined or angled spaces
• Use with manual screwdrivers and bit holders that accept hex shanks
• Applications requiring extended reach for recessed fasteners

How to use

Select a bit that matches the hex-socket fastener size, insert the hexagonal shank firmly into a compatible driver or bit holder, and engage the fastener. For angled access, use the ball end and work up to a 25° angle while maintaining steady pressure to prevent cam-out. After use, wipe bits clean and store them in a suitable case or holder to protect the lasered markings and coating.

Usage recommendations

Use the bits with drivers and holders rated for hex shanks and apply appropriate torque to avoid overloading. Inspect bits regularly for wear or rounding, and replace if damage or excessive wear is observed to maintain secure fastening and user safety.
