The HILLMAN FASTENERS 9185 is a T15 star-drive drill bit sized at 2 inches in overall length. It is designed for driving T15 Torx-style fasteners in wood, light metal, and composite materials. This bit is a standard hand-tool accessory used by electricians, plumbers, HVAC technicians, and general contractors when installing equipment panels, access doors, and fixture hardware that use star-drive screws. The compact 2-inch length fits standard 1/4-inch hex-shank power drivers and impact drivers commonly found on the job site.
This bit is suited for light-duty fastening tasks in residential and commercial service work. It is particularly useful when working with equipment enclosures, electrical panels, and HVAC access covers that use T15 star-drive hardware. Sold as a single pack, it is a practical addition to any service technician's bit set for on-demand replacement or backup use.
Designed as a standard replacement or backup T15 star-drive bit compatible with 1/4-inch hex-shank power drivers and impact drivers that accept T15 Torx-style fasteners.
Install and remove using any 1/4-inch hex-shank power driver or manual bit holder. Ensure the driver is set to an appropriate torque setting to avoid cam-out or fastener damage. Inspect the bit tip for wear before use, as a worn T15 profile increases the risk of stripping fastener heads.
