Apex 49-B-TX-20 T20 Torx Power Screwdriver Bit 1/4 in Hex

Product Description

The APEX 49-B-TX-20 is a T20 Torx power screwdriver bit designed for use with 1/4 inch hex drive power tools and bit holders. With an overall length of 3.5 inches, this bit provides added reach in tight or recessed fastener applications. The 0.17 inch body diameter and 4.30 mm body diameter are sized for standard T20 Torx fasteners found across HVAC equipment panels, electrical enclosures, and plumbing fixture assemblies. This bit is sold as a single piece and is intended for professional tradespeople who require consistent, precise fastener drive performance in daily service work.

The 49-B-TX-20 is suited for any trade application requiring a T20 Torx drive, including HVAC equipment access panels, electrical junction box covers, and light commercial service work. The 3.5 inch overall length makes it practical for power screwdrivers and impact-ready bit holders in service and installation scenarios where a standard-length bit lacks sufficient reach.

Installation Notes

This bit is installed by trade professionals into any 1/4 inch hex drive power tool or manual screwdriver with a hex chuck. Ensure the bit is fully seated in the holder before applying torque to prevent cam-out or bit damage. When servicing live electrical equipment or pressurized systems, follow applicable NEC, IFGC, or IPC lockout and de-energization procedures before removing fastened covers or panels.
