Wiha 76877 Impact Torx Bit Socket Set 10 Pc 1/4 Drive

Product Description

The WIHA 76877 is a 10-piece impact Torx bit socket set designed for use with 1/4-inch drive tools. The set covers T10 through T40 Torx sizes, making it suitable for a wide range of fastener applications in mechanical, electrical, and HVAC service work. Each bit features a red molded torsion zone coating that absorbs rotational shock during impact driver use, reducing stress on both the bit and the fastener. The set stores on a compact rail for organized access in a toolbox or service bag. It is a practical addition to any trade professional's socket collection.

This set is intended for technicians who regularly encounter Torx fasteners on equipment panels, motor assemblies, control boards, and enclosures. The seven included Torx sizes — T10, T15, T20, T25, T27, T30, and T40 — address the most common fastener sizes found in HVAC equipment, electrical panels, and light commercial applications. The 1/4-inch drive format is compatible with standard ratchets, extension bars, and impact drivers equipped with a 1/4-inch hex or square drive adapter.

Installation Notes

This set is a hand and power tool accessory installed by any trade professional working with Torx fasteners.
