Proto J77274P Impact Socket 3/8 in Drive 7/16 in 6-pt

Product Description

The PROTO J77274P is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. It accepts a 7/16 inch hex fastener and delivers the torque transfer needed for impact-rated applications in mechanical, HVAC, plumbing, and general trade work. Constructed from alloy steel, the socket meets ASME B107.2 standards for impact tooling. The overall length of 2 inches keeps the profile compact for access in tighter fastener locations. This socket is appropriate for any licensed tradesperson or shop technician working with 3/8 inch drive impact tooling.

This socket is suited for residential and commercial service applications where 7/16 inch hex fasteners are common — including equipment panels, structural brackets, pipe hangers, and mechanical assembly work. The universal style makes it a practical addition to a 3/8 inch drive impact set for field and shop use. Its compact 2 inch overall length is well suited to situations where clearance around the fastener is limited.

Installation Notes

Install and remove with a 3/8 inch drive impact wrench or ratchet. Always ensure the socket is fully seated on the fastener before applying torque to prevent fastener damage or socket disengagement. Inspect the socket for cracks or wear before each use — do not use impact sockets that show signs of deformation. Follow applicable workplace safety guidelines when operating pneumatic or electric impact tools.
