Proto J7309M Impact Socket 1/2 in Drive 9mm 6-point

Product Description

The PROTO J7309M is a 9mm, 6-point impact socket designed for use with 1/2 inch drive impact wrenches and rattle guns. Built for high-torque fastening and removal tasks, it features a hex drive style and measures 3.25 inches overall length. The 6-point contact geometry reduces the risk of fastener rounding under heavy impact loads. This socket is sized and built for professional mechanics, maintenance technicians, and trade professionals who rely on impact tooling in demanding shop or field environments.

The J7309M is suited for automotive, industrial, and mechanical maintenance applications where a 9mm fastener is common. Typical uses include suspension work, equipment repair, and general mechanical assembly or disassembly requiring impact-rated tooling. The 1/2 inch drive size makes it compatible with standard 1/2 inch impact wrenches and torque wrenches used across commercial and industrial trades.

Key Features

• 1/2 inch drive fits standard impact wrenches and torque wrenches
• 9mm socket size for metric fastener applications
• 6-point hex drive reduces fastener rounding under impact torque
• 3.25 inch overall length provides reach in tighter fastener locations
• Impact-rated construction designed for use with pneumatic and electric impact tools

Compatibility

Designed as an OEM-style impact socket for use with 1/2 inch drive impact wrenches and drive tools requiring a 9mm 6-point metric socket.

Installation Notes

Installation is performed by mechanics and maintenance technicians using 1/2 inch drive impact or hand tools. Always verify the socket is fully seated on the fastener before applying torque. Inspect the socket for cracks or wear before each use, and do not use impact sockets on hand-ratchet drives beyond their rated capacity. Replace any socket showing visible deformation or damage.
