Wiha 71437 Power Screwdriver Bit 1/4 in Hex 6 in Oal

Product Description

The WIHA 71437 is a power screwdriver bit designed for use with 1/4 inch hex drive power tools and impact drivers. Built from chrome vanadium molybdenum steel, it delivers the torsional strength and wear resistance required for repetitive fastening in demanding trade environments. The bit measures 6 inches overall length, giving technicians added reach in tight or deep access points. At 0.11 pounds, it is lightweight enough for all-day use without adding fatigue. Electricians, HVAC technicians, and general contractors working with power-drive applications will find this bit well-suited for production fastening tasks.

This bit is appropriate for residential and light commercial applications where a 1/4 inch hex shank is the standard interface. The 6 inch overall length suits installations requiring extended reach, such as panel work, equipment assembly, and structural fastening. It is sold as a single piece, making it a practical direct replacement when a bit wears out on the job. Compatible with any 1/4 inch hex quick-change chuck found on cordless drills, impact drivers, and dedicated power screwdrivers.

Key Features

• 1/4 inch hex drive shank fits standard quick-change power tool chucks
• 6 inch overall length provides extended reach for deep or confined fastening locations
• Chrome vanadium molybdenum construction resists wear and torsional stress under power-drive loads
• 0.312 inch body diameter for positive engagement and reduced cam-out tendency
• Single-piece packaging for straightforward replacement stock

Compatibility

Designed as an OEM-style replacement bit for any power tool or hand driver accepting a 1/4 inch hex shank insert bit.

Installation Notes

Installation requires no tools beyond the power driver itself. Ensure the quick-change chuck is fully seated and locked before applying torque. Inspect the bit tip for wear or deformation before each use, as a worn tip increases cam-out risk and can damage fastener heads. Dispose of worn bits rather than continuing to use them under load.
