Wiha 70163 Tamperproof Torx Bit T30 1/4 Inch Drive 10-pack

Product Description

The WIHA 70163 is a T30 tamperproof Torx screwdriver bit designed for use with 1/4 inch hex drive tools. Built from steel, this security bit features the center-pin bore required to engage tamper-resistant T30 Torx fasteners commonly found in HVAC equipment panels, electrical enclosures, pool equipment housings, and other trade-grade assemblies. The overall length is 25 millimeters (approximately 1 inch), making it compatible with standard 1/4 inch bit holders, impact-rated adapters, and magnetic bit extensions. Each order contains 10 bits, making this pack a practical supply for field technicians who go through bits frequently.

This bit is suited for residential and commercial service work wherever tamper-resistant Torx fasteners are used. HVAC technicians will encounter T30 security fasteners on equipment covers, fan blade assemblies, and control panel enclosures. Electricians and pool service professionals similarly encounter security Torx hardware on meter bases, junction boxes, and pump motor covers. The 1/4 inch drive hex shank fits standard power screwdrivers, cordless drills, and manual bit holders used daily in the trade.

Key Features

• T30 tamperproof Torx profile with center-pin bore for security fastener engagement
• 1/4 inch (6 mm) hex shank fits standard 1/4 inch drive bit holders and adapters
• 25 mm overall length for use in tight-access panel and enclosure work
• Steel construction for durability under repeated torque loading
• Pack of 10 bits reduces downtime from worn or lost bits on multi-job days

Compatibility

Designed for use with any 1/4 inch hex drive tool accepting standard screwdriver bits, including manual bit holders, cordless drills, and impact drivers with appropriate adapters. Engages T30 tamper-resistant Torx fasteners only.

Installation Notes

Always de-energize and lock out electrical or mechanical equipment before removing tamper-resistant fasteners from panels or enclosures. Use the correct T30 security bit to avoid fastener head damage — standard T30 bits without the center bore will not seat properly in tamper-resistant hardware. Worn bits should be replaced promptly, as a damaged bit tip can strip security fastener heads and complicate service access.
