Wera 05028161001 Bit Screwdriver 1/4 Inch Hex Drive

Product Description

The WERA 05028161001 is a 393 S Bitholding Screwdriver Extra Slim with Flexible Shaft, designed for use with 1/4 inch hex drive bits. The tool features a Kraftform ergonomic handle that reduces hand fatigue during extended fastening tasks. With an overall length of 10.69 inches and a blade length of approximately 6-53/64 inches, this bit screwdriver reaches fasteners in tight or recessed locations where standard rigid drivers cannot. The flexible shaft allows angled driving without requiring a separate flex extension. Weighing 0.26 pounds, it is lightweight enough for continuous overhead or confined-space work. Electricians, HVAC technicians, and mechanical contractors will find this driver well suited to panel work and equipment assembly.

This bit screwdriver is intended for professional trade use in residential and commercial applications. The slim profile and flexible shaft make it particularly useful when fasteners are partially obstructed or set at awkward angles relative to the work surface. It accepts standard 1/4 inch hex shank bits, making it compatible with common insert bit sets already carried by most technicians. Typical installation scenarios include junction box assembly, equipment panel fastening, and mechanical equipment access work where clearance is limited.
