Product Description

The WIHA 74317 is a power screwdriver bit designed for use with power drivers and impact-ready tools in professional trade applications. Built from steel construction, this bit features a 0.187-inch hex drive size and a 2-inch overall length, making it suited for standard hex fastener driving tasks. The non-magnetic design keeps the bit free from debris attraction in metal-rich work environments.

This bit is appropriate for use in residential and light commercial service environments where standard hex fasteners are common. Typical install scenarios include panel work, equipment mounting, junction box assembly, and general mechanical fastening. The 2-inch overall length provides adequate reach for recessed fastener locations without excessive flex. The 10-piece pack quantity supports high-volume use in shop, van, or job-site settings.
