Bit Torx Wiha T15, acciaio cromo-vanadio, temprato, attacco 1/4" (E 6.3)

wiha Torx bit T15 made from Chrom-Vanadium steel is a hardened insertion tool designed for use with E 6.3 (1/4") drives. The bit's T15 profile ensures accurate fit and torque transfer to Torx fasteners, while the heat-treated material improves edge strength and wear resistance for repeated assembly and maintenance operations. It is intended for situations that require a compact, durable Torx bit compatible with common 1/4" bit holders and ratchets.

Advantages

The hardened Chrom-Vanadium construction provides increased toughness and longer service life under frequent use. Precise machining of the T15 profile reduces cam-out and ensures consistent engagement with Torx fasteners. Compatibility with standard E 6.3 (1/4") drive systems makes the bit convenient to integrate into existing tool sets and quick-change holders. The compact single-bit form factor is suitable for confined spaces and handheld screwdriving tasks.

How to use

Insert the wiha T15 Torx bit into an E 6.3 (1/4") bit holder or directly into a compatible ratchet or driver. Ensure the bit is fully seated to prevent slippage. Use steady, controlled torque appropriate for the fastener size to avoid damage to the bit or the fastener head. After use, inspect the Torx tip for wear or rounding and replace the bit when engagement becomes loose to maintain safe and effective operation.

Recommendations

For best results, pair this hardened T15 bit with a torque-limited screwdriver or a controlled torque driver when working on sensitive assemblies. Store the bit in a dedicated holder to protect the tip geometry and maintain precise engagement with Torx fasteners.
