Proto J7210PF Power Socket 3/8 in Drive 5/16 in Hex

Product Description

The PROTO J7210PF is a 3/8 inch drive power socket designed for high-torque fastening applications in professional trade environments. It features a 5/16 inch hex size, a 6-point contact geometry that reduces fastener rounding under load, and a magnetic design that retains fasteners during positioning. The black finish provides corrosion resistance in shop and field conditions. This socket is built for mechanics, electricians, HVAC technicians, and other trades who rely on impact-rated or power-drive tooling for repetitive fastener work.

The J7210PF is suited for use with 3/8 inch drive impact wrenches, air ratchets, and electric power drivers in residential, commercial, and light industrial settings. The magnetic retention feature makes it particularly useful in overhead or confined-space installations where dropped fasteners are a practical concern. Typical applications include equipment assembly, panel work, and mechanical fastening tasks requiring consistent torque delivery at the 5/16 inch hex size.

Key Features

• 3/8 inch drive size compatible with standard 3/8 inch drive impact and ratchet tools
• 5/16 inch hex opening for precise fastener engagement
• 6-point design reduces corner rounding on hex fasteners under load
• Magnetic socket retains fasteners for single-hand placement
• Black finish for corrosion resistance in field use
• Lifetime warranty from PROTO

Compatibility

Designed as an OEM-style replacement or direct-use socket compatible with standard 3/8 inch drive impact wrenches, air ratchets, and power drivers requiring a 5/16 inch hex socket.

Installation Notes

Install and remove using standard 3/8 inch drive tooling. Ensure the drive tool is rated for the torque demands of the application before use with power or impact drivers. Inspect the socket for wear or cracking before each use, and replace if deformation is visible. No power disconnection is required for the socket itself, but always follow appropriate lockout/tagout procedures when working on energized equipment.
