Proto j54118s 1/2 in Drive Sae Socket Set 18 Piece

Product Description

The PROTO j54118s is an 18-piece, 1/2 in drive SAE socket set built for hand-use on inch-size fasteners. The set includes 15 standard 6-point sockets ranging from 3/8 in through 1-1/4 in, along with drive tools to provide the leverage needed to tighten and loosen fasteners efficiently. Each socket carries a chrome finish for corrosion resistance. The 6-point contact geometry reduces fastener rounding compared to 12-point designs, making it a reliable choice for service and repair work. The set ships in a case that keeps sockets organized and accounted for on the job. It is suited for automotive, mechanical, and general maintenance trades.

This socket set is designed for hand-drive applications where 1/2 in drive tooling is standard. The SAE sizing makes it appropriate for equipment and vehicles using inch-standard fasteners. Typical use cases include automotive repair, equipment servicing, and mechanical maintenance work where socket sizes in the 3/8 in to 1-1/4 in range are commonly encountered. The included drive tools mean the set is ready to use out of the case without requiring additional handle purchases. It is not impact rated and should be used with hand ratchets, breaker bars, or similar hand-drive tools only.

Installation Notes

This set is intended for hand-drive use only — do not use with impact wrenches or pneumatic tools as the sockets are not impact rated. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage or fastener damage. Inspect sockets for cracks or wear before each use and remove any damaged socket from service.
