The APEX 440-TX-30-H is a T30 Torx screwdriver bit designed for use with 1/4 inch hex drive tools. Built from steel, this bit delivers consistent torque transfer in demanding trade applications. The tamper-resistant design addresses fasteners that require specialized tooling, preventing unauthorized disassembly. At 1 inch overall length (OAL), it fits standard bit holders, impact drivers, and ratcheting screwdrivers used daily in HVAC, electrical, and plumbing service work. The 1/4 inch hex shank seats securely in quick-change chucks without additional adapters.
This bit is suited for residential and light commercial service work where T30 Torx fasteners appear on equipment panels, access covers, motor mounts, and electrical enclosures. HVAC technicians, electricians, and plumbers frequently encounter tamper-resistant Torx fasteners on equipment requiring periodic service access. The compact 1 inch OAL keeps the profile low in tight spaces common in mechanical rooms, electrical panels, and equipment cabinets.
Designed for use with any 1/4 inch hex drive bit holder, ratchet, screwdriver handle, or impact driver accepting standard 1/4 inch shank bits.
Install and remove only with compatible 1/4 inch hex drive tools rated for the fastener torque requirements of the application. Ensure the bit is fully seated in the drive chuck before applying torque to prevent cam-out or fastener damage. Do not use with impact drivers at maximum torque settings on fasteners that may strip at lower values. Inspect the bit tip for wear before each use and replace if the Torx lobes show rounding or deformation.
