Proto J7208MHF Impact Socket 3/8 in Drive 8mm 6-point

Product Description

The PROTO J7208MHF is a 3/8 inch drive, 8mm impact socket designed for high-torque fastener work in professional trade environments. Built from alloy steel with a 6-point hex drive configuration, it delivers reliable torque transfer to hex fasteners without rounding. The magnetic retention feature holds the fastener securely during positioning, which reduces fumbling in tight spaces. Overall length is 1-3/32 inches. At 0.07 pounds, it is a compact, lightweight socket suitable for mechanics, millwrights, and maintenance technicians working with metric hex fasteners on production and service applications.

This socket is suited for use with 3/8 inch drive impact wrenches and ratchets in automotive, industrial, and general mechanical service. The 8mm hex drive size is common in engine accessory mounting, bracket hardware, and light structural fastener applications. The 6-point design concentrates force on the flats of the fastener rather than the corners, reducing the risk of fastener damage under impact loads. Magnetic retention makes it practical for overhead or inverted installations where dropping hardware is a concern.

Key Features

• 3/8 inch drive fits standard impact wrenches and ratchets
• 8mm hex drive size for metric hex fasteners

Compatibility

Designed for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring an 8mm hex drive socket.

Installation Notes

Install and remove using a 3/8 inch drive impact wrench or ratchet. Verify the socket seats fully on the fastener hex before applying torque. Inspect the socket for cracks or wear before each use, and replace if deformation is visible. Do not use impact sockets on torque-sensitive fasteners without a calibrated torque wrench as the final step where specifications require it.
