Wiha 28531 T15 Torx Torque Blade Bit 8-3/4 in 1/8 Hex

Product Description

The WIHA 28531 is a T15 Torx torque blade screwdriver bit designed for use with compatible 1/8 inch hex-drive handles and torque-limiting screwdrivers. At 8.75 inches overall length, this bit provides extended reach in confined or deep-access fastening applications. The Torx drive profile delivers torque transfer directly to the fastener head, reducing cam-out and fastener damage compared to Phillips or slotted profiles. The bit weighs 0.07 pounds, making it a lightweight addition to any tool kit. Licensed electricians, HVAC technicians, and general service technicians use this style of bit when precision fastening is required on equipment panels, control boards, and enclosures.

The WIHA 28531 is suited for professional service work where T15 Torx fasteners are common, including HVAC equipment panels, electrical enclosures, and electronic control assemblies. The 1/8 inch hex shank fits standard bit-holding screwdrivers and torque handles designed for that drive size. This is a single-piece replacement bit sold individually, making it a practical option for restocking tool kits or replacing worn bits in the field.

Installation Notes

Always de-energize equipment before accessing fastened panels or control enclosures. Verify the hex shank seats fully and locks into the bit holder before applying torque. Use with a torque-limiting handle when fastener specifications call for controlled torque values. Inspect the Torx tip for wear before each use and replace if the drive lobes are rounded or chipped.
