Williams Comfort Products JHW37820 Impact Socket 20MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHW37820 is a 20 MM metric impact socket built for heavy-duty fastener work in professional trade environments. Featuring a 1/2 inch drive and a 3 inch overall length, this socket is engineered with SUPERTORQUE lobular openings that apply rotational force to the flat sides of a fastener rather than the corners, reducing the risk of rounding or deforming the fastener head. Specially heat treated for impact use, it delivers the strength and durability required for sustained use with pneumatic and electric impact wrenches. The drive end includes a pin retention hole and groove to secure impact retaining pins or rings during use.

This socket is suited for mechanical, industrial, and heavy equipment service applications where metric fasteners are standard. The universal impact design makes it appropriate for automotive repair shops, fleet maintenance facilities, equipment service centers, and general mechanical contracting work. At 3 inches overall length, it fits into confined spaces while maintaining full engagement on 6-point fasteners. Technicians working in HVAC, electrical, plumbing, and related trades will find it a reliable tool for equipment installation and service calls requiring metric hardware removal or installation.
