Starrett 50420 Straight Handle Tap Wrench 3/16 to 1/2 in

Product Description

The STARRETT 50420 is a straight-handle tap wrench designed for hand-tapping operations in metal, plastic, and other materials. It accepts taps ranging from 3/16 to 1/2 inches in tap capacity, covering a broad range of threading tasks common in plumbing, HVAC, and mechanical service work. The wrench spans 9 inches in overall length, giving the technician adequate leverage without excessive torque that could break smaller taps. The non-ratcheting straight handle design provides direct, tactile feedback during threading, which helps experienced tradespeople feel resistance changes and avoid tap breakage. This tool is a staple in any service van or shop where field tapping is a regular task.

The STARRETT 50420 suits residential and light commercial maintenance applications where hand-tapping threaded holes is required on-site or at the bench. It is commonly used by HVAC technicians, plumbers, pipefitters, and general maintenance mechanics when chasing or cutting threads in tight or awkward locations where a tap handle with a straight profile is preferred over a T-handle. The pipe tap range accommodates 1/8 inch pipe taps, making it useful for adding or restoring threaded ports on fittings, brackets, and equipment housings.

Installation Notes

This tool is intended for use by qualified tradespeople performing hand-tapping operations. Always secure the workpiece before threading to prevent movement. Apply cutting fluid appropriate for the material being tapped to reduce friction and extend tap life. Do not apply excessive downward force on the wrench; let the tap cut at its own rate to avoid breakage.
