Screwdriver bit set KWB 121610 — 3 pcs, Tamper Torx tips, Steel, 25 mm length, 1/4" shank

The KWB 121610 screwdriver bit set includes three steel bits with Tamper Torx tips designed for secure engagement with tamper-resistant fasteners. Each bit measures 25 mm in working length and is fitted with a 1/4" (6.35 mm) hex shank that fits standard bit holders and power drivers. The set is intended for repair, assembly and maintenance tasks where tamper-proof screws are used and where reliable bit retention and torque transfer are required.

Advantages

Manufactured from steel for durability, the bits provide a precise fit to Tamper Torx screw heads to reduce cam-out and wear. The 25 mm length offers a balance between compact access in tight spaces and sufficient reach for recessed fasteners. The 1/4" hex shank ensures compatibility with common bit holders, ratchets and cordless drivers, enabling fast interchange and stable mounting during use.

Suitable for

• Repair and maintenance of appliances and electronics with tamper-proof screws
• Assembly tasks where secure, tamper-resistant fastening is required
• Professional and DIY applications involving recessed or protected Torx fasteners

Key specifications

How to use

Select the correct Tamper Torx bit size for the screw head to ensure a snug engagement of the recess pin and star profile. Insert the 1/4" hex shank into a compatible bit holder, screwdriver handle or cordless driver, then apply steady axial pressure while turning to avoid slippage. For recessed screws, use the 25 mm working length to reach the fastener while maintaining control; for limited-access locations, ensure the bit aligns coaxially with the screw to prevent damage to the screw head.

Usage recommendations

Inspect bits for wear before use and replace when rounding or deformation is visible. Use appropriate torque settings on powered drivers to prevent over-tightening tamper-resistant fasteners. Store bits in a dry place to limit corrosion and keep them organized to preserve tip geometry and ensure long service life.
