Proto J4778TA 11/32 Inch 12-point Hand Socket 1/4 Drive

Product Description

The PROTO J4778TA is an 11/32 inch, 12-point hand socket designed for use with 1/4 inch drive ratchets and extensions. Constructed from alloy steel with a chrome-plated finish, it delivers the corrosion resistance and durability required for repeated use in professional service environments. The 12-point design allows engagement at multiple positions around the fastener, reducing repositioning time in tight spaces. The universal/flex socket type adds versatility for angled fastener access. This socket is well suited for HVAC technicians, electricians, plumbers, and general trade professionals who need a compact, reliable fastener tool in their kit.

This socket is intended for hand-tool use in light-to-medium duty fastener applications. Its compact 1/4 inch drive size makes it appropriate for work in confined equipment panels, electrical enclosures, and mechanical assemblies where larger drive sizes cannot fit. The chrome finish aids in keeping the socket clean and resistant to shop-environment corrosion over time.

Installation Notes

This socket is installed and removed by hand using a 1/4 inch drive ratchet, extension, or T-handle. Ensure the fastener is properly seated in the socket before applying torque to avoid rounding. Inspect the socket for cracks or excessive wear before each use and replace if the chrome finish is deeply worn or the socket walls show deformation.
