Disston Company 696636 No. 1 Square Recessed 2in Screwdriver Bit

Product Description

The DISSTON COMPANY 696636 is a No. 1 square recessed screwdriver bit designed for use with power drivers and impact tools in professional trade applications. Measuring 2 inches in length, this bit is manufactured from shock-resistant tool steel using an advanced hardening process that extends service life under high-cycle and high-torque conditions. The snub nose design improves bit engagement and reduces cam-out, making it a practical choice for fastening tasks where durability and consistent performance are required. Weighing approximately 0.03 pounds, it is a lightweight, single-piece insert bit sized for standard quick-change holders.

This bit is suited for residential and light commercial construction, millwork, cabinetry, decking, and general mechanical assembly where No. 1 square drive fasteners are specified. It is commonly used by carpenters, general contractors, electricians, and plumbers for panel and fixture fastening. The 2-inch length fits most standard bit holders and right-angle attachments commonly found on job sites. The shock-resistant construction makes it appropriate for use with both corded and cordless impact drivers operating at standard torque ranges.
