Wiha 74357 Power Screwdriver Bit 1/4 in Drive 10-pack

Product Description

The WIHA 74357 is a power screwdriver bit designed for use with power drivers and impact-rated tool systems in professional trade applications. Manufactured from steel, this bit measures 2.75 inches overall length (OAL) and accepts a standard 1/4 inch hex drive shank with an 8 mm hex size. It is sold in a pack of 10, making it a practical replenishment option for service vehicles and job-site kits. The non-magnetic construction suits applications where magnetic attraction to fasteners or surfaces is undesirable. Electricians, HVAC technicians, plumbers, and general contractors will find this bit compatible with standard power screwdrivers and hex-drive adapters.

This bit is suited for repetitive fastening tasks in both residential and light commercial settings. The 2.75 inch OAL provides additional reach compared to short-series bits, which is useful when driving fasteners in recessed locations or through panels. The 10-piece pack quantity supports team use or high-volume fastening workflows without frequent restocking.

Compatibility

Designed as a standard replacement power screwdriver bit for use with 1/4 inch hex-drive power screwdrivers and impact drivers commonly used in HVAC, electrical, and general trade service work.

Installation Notes

Insert the bit fully into the tool chuck before operating to ensure positive seating in the hex receiver. Verify the chuck is locked and the tool is set to the appropriate torque or speed setting for the fastener type before driving. Inspect bits regularly for wear or deformation and replace any bit that shows cracking, rounding, or tip damage, as a damaged bit can strip fasteners or slip unexpectedly during use.
