Proto J1270B Flex Head Combo Wrench Set 4 Pc Inch

Product Description

The PROTO J1270B is a 4-piece flex head combination wrench set sized in inch measurements and finished in satin. Each wrench features a 12-point box end on a flexible head, allowing the user to work in tight or awkward spaces where a standard fixed-head wrench cannot seat properly. The open end handles straight-pull fastener access. The satin finish reduces glare in bright work environments and resists corrosion over time. This set is aimed at mechanics, HVAC technicians, pipefitters, and general maintenance professionals who need a compact, travel-ready inch wrench kit stored in a nylon tool roll.

This wrench set covers four common inch fastener sizes used across HVAC equipment, plumbing fixtures, gas appliances, and general mechanical assemblies. The flex head design is particularly useful when accessing flare fittings, valve stems, and fasteners recessed behind panels or tubing runs. The included nylon tool roll keeps all four wrenches organized and protected during transport to and from job sites.
