Proto J7216S Impact Socket 3/8 in Drive 1/2 in 8-pt

Product Description

The PROTO J7216S is an 8-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. It accepts 1/2 inch fasteners and measures 1-1/16 inches in overall length, making it a compact option for tight-clearance work. The 8-point geometry is engineered to engage square and 8-point fastener heads with reduced slippage under high torque impact loads. Weighing 0.13 pounds, this socket is suited for professional mechanics, maintenance technicians, and tradespeople who require reliable drive tooling in demanding shop or field environments.

This socket is appropriate for use in automotive, industrial, and general mechanical maintenance applications. The 3/8 inch drive size is a common mid-range platform used across a wide variety of impact and hand-drive tools. The compact 1-1/16 inch overall length allows access in spaces where longer sockets would not fit. It is used wherever 1/2 inch 8-point fasteners are encountered during disassembly, assembly, or service work.

Key Features

• 3/8 inch drive fits standard mid-range impact wrenches and ratchets
• 1/2 inch socket size for 8-point fastener engagement
• 8-point geometry reduces fastener rounding under impact loads
• 1-1/16 inch overall length for compact fitment in tight spaces

Compatibility

Designed as an OEM-style replacement and service socket for use with 3/8 inch drive impact tools requiring an 8-point 1/2 inch socket.

Installation Notes

This socket is installed and used by professional mechanics and maintenance technicians. Before use, confirm the drive tool is rated for impact service and that the socket is fully seated on the drive anvil. Inspect the socket for cracks or wear before each use, and never use impact sockets on hand-ratchets beyond their rated torque capacity.
