Screwdriver bit Wiha T15H 2.5 cm steel, 1/4" hex shank

Wiha T15H screwdriver bit in hardened steel, 2.5 cm long with a 1/4" hex shank designed for Torx T15 fasteners. The compact length makes the bit suitable for use in tight spaces and in quick-change bit holders. Engineered to deliver precise fit and reliable torque transfer, this bit is intended for assembly, maintenance, and repair tasks where durability and accurate engagement with Torx screws are required.

Advantages

The bit is made from hardened steel to resist wear during repeated use. A precisely machined Torx profile ensures secure engagement with T15 fasteners, reducing the risk of cam-out. The standard 1/4" hex shank provides compatibility with common bit holders, ratchets, and quick-change chucks, enabling fast swapping and convenient operation. Its short 2.5 cm length offers improved access in confined areas and better control for precise tightening.

Suitable for

• Assembly of small mechanical and electronic components
• Maintenance and repair of appliances and machinery with Torx T15 screws
• Work in confined or recessed fastening locations
• Use with 1/4" bit holders, quick-change systems, and hand drivers

Key specifications

• Tip type: Torx T15
• Material: hardened steel
• Length: 2.5 cm
• Shank: 1/4" hex
• Finish: machined for precise fit
• Compatibility: standard 1/4" bit holders and quick-change systems

How to use

Insert the 1/4" hex shank into a compatible bit holder, ratchet or quick-change chuck until it locks. Position the Torx T15 tip fully into the screw recess to ensure correct engagement, then apply steady torque while keeping the bit aligned with the screw axis. For best results, use appropriate torque settings on powered drivers and avoid excessive force that can deform the screw head or bit tip. After use, inspect the tip for wear and store the bit in a dedicated holder to maintain its condition.

Usage recommendations

Use the bit with the correct Torx T15 size to prevent cam-out and rounding of screw heads. For high-torque or impact applications choose bits and holders rated for those tools; avoid using a worn tip on critical fastenings. Regularly check the bit for signs of wear and replace when fit is no longer precise.
