Wiha 74315 Power Screwdriver Bit 0.14 in Hex 2 in 10 Pc

Product Description

The WIHA 74315 is a 10-piece set of power screwdriver bits designed for use with power tools and impact-rated drivers in professional trade applications. Each bit features a 0.14-inch hex drive size and a 2-inch overall length, providing reach and torque transfer suited to fastening tasks in tight or standard-clearance work areas. Constructed from steel, these bits are built to handle the rotational stress of power driving. Electricians, HVAC technicians, and general trade professionals who rely on power screwdrivers or drill-drivers for repeated fastening tasks will find this set a practical bench and field supply.

These bits are suited for standard hex fastener applications in residential and commercial service environments. The 2-inch overall length fits standard bit holders and quick-change chucks common on cordless drills and power screwdrivers. The 10-piece quantity makes this set appropriate for stocking a tool bag or service van where bit wear and loss are routine considerations. Tasks such as panel cover fastening, equipment assembly, and general fastener driving in HVAC, electrical, and plumbing rough-in work are typical use cases.

Installation Notes

Installation of these bits requires seating the hex shank fully into the bit holder or quick-change chuck before operation to prevent slippage under load. Inspect bits for wear or deformation before each use, as damaged bits can strip fastener heads. Always ensure the driver tool is powered off or the battery is removed before changing bits. Follow applicable NEC or trade-specific fastener torque guidelines as required by the job scope.
