The DISSTON COMPANY 773481 is a T27 Torx screwdriver bit designed for use with standard power drills, impact drivers, and bit holders. Built from shock resistant tool steel, this 2-inch bit is engineered to handle the torque demands of fastening and removal tasks without chipping or deforming at the tip. The shock resistant construction extends bit life under repeated impact driver use, making it a practical choice for technicians who cycle through fasteners at high volume. Licensed and sold under the Master Mechanic line, this bit suits both bench work and field service applications.
This T27 Torx bit is commonly used in automotive service, including headlight assemblies, interior trim panels, and other vehicle components that use Torx fasteners. The 2-inch length provides clearance in recessed fastener locations while remaining compatible with most standard bit holders and quick-change chucks. Electrical, HVAC, and general maintenance technicians will also encounter T27 fasteners on equipment enclosures, access panels, and control components.
Designed as a replacement or supplemental T27 Torx bit for use with 1/4-inch hex drive power tools and manual screwdrivers. Commonly used in automotive service including headlight assemblies and related fastener applications.
Install this bit into a 1/4-inch hex drive impact driver, drill, or manual bit holder before applying torque. Verify the bit is fully seated in the fastener recess before driving to prevent cam-out and tip wear. When using with an impact driver, select the appropriate torque setting for the fastener material to avoid stripping. Inspect the bit tip regularly for wear and replace if rounding or deformation is observed.
