Wiha 71924 Torq-set Insert Bit 3 Point 6.3 Mm Hex Drive

Product Description

The WIHA 71924 is a Torq-Set screwdriver insert bit designed for use with standard 6.3 mm (1/4 inch) hex drive bit holders and power tools. It features a No. 3 Torq-Set point, which engages the cruciform Torq-Set screw head pattern commonly found in aerospace, military, and precision equipment assemblies. The steel construction provides the toughness needed for repeated insertions and consistent torque transfer. At 25 mm overall length, this insert bit fits most standard bit holders and quick-change chucks used in production and service environments. Technicians across aerospace, electronics, and defense maintenance sectors rely on this bit for accurate, non-slip engagement with Torq-Set fasteners.

The 71924 is suited for maintenance, repair, and assembly applications where Torq-Set fasteners are specified. These fasteners appear frequently in aircraft interiors, military equipment, and high-security mechanical assemblies. The insert bit format makes it compatible with impact-rated and manual hex bit holders used by both field service technicians and assembly line workers. It is sold in packages of 10, making it practical for tool crib restocking or multi-technician kits that require consistent bit availability across a crew.

Installation Notes

Insert bits should be seated fully into the bit holder before engaging the fastener to prevent cam-out or bit ejection. Confirm the Torq-Set point size matches the fastener before applying torque. When used in powered drivers, set the clutch to an appropriate torque level for the fastener size to avoid fastener or bit damage. No special certifications are required to use hand tool insert bits, though technicians should follow any applicable equipment or facility standards governing fastener torque requirements.
