Proto J5446H 1-7/16 in 6-point 1/2 Drive Hand Socket

Product Description

The PROTO J5446H is a 6-point hand socket designed for professional use in mechanical, industrial, and maintenance applications. Built from alloy steel with a chrome-plated finish, this socket fits a 1/2 inch drive and accepts a 1-7/16 inch fastener. The 6-point design applies force to the flat sides of a fastener rather than the corners, reducing the risk of rounding off hex heads under high torque. At a standard length of 2.125 inches overall, the J5446H is suited for general-access fastener work without the added reach of a deep socket. It meets ASME B107.1 standards for hand sockets.

This socket is used in automotive, heavy equipment, and general mechanical service where a 1-7/16 inch fastener and 1/2 inch drive are required. The standard length profile works in most open-access situations. It is appropriate for use with 1/2 inch drive breaker bars, ratchets, and torque wrenches. Trades that commonly use this socket include millwrights, diesel mechanics, industrial maintenance techs, and automotive service technicians.

Installation Notes

This socket is installed by licensed mechanics and qualified trade professionals. Ensure the drive tool and socket are fully seated before applying torque to prevent slippage or socket ejection. Do not use hand sockets with impact drivers unless the socket is rated for impact use. Inspect the socket for cracks or deformation before each use and remove it from service if damage is found.
