Frequently Asked Questions

What is the PROTO Flex Impact Socket used for?

The PROTO Flex Impact Socket is used for fastening and loosening metric fasteners in high-torque applications, such as automotive repair and industrial maintenance. Its 11 mm, 6-point design provides a secure grip on hex bolts and nuts, while the flex joint allows access to fasteners in tight or awkward spaces.

What are the specifications of the PROTO Flex Impact Socket J77411MP?

The PROTO Flex Impact Socket J77411MP has an 11 mm socket size, 6-point standard configuration, and a 3/8" drive. It features a Black Oxide finish for corrosion resistance and is Not Tether Capable. This metric socket is designed for impact tools and is manufactured by PROTO under part number J77411MP.

How to select the correct PROTO Flex Impact Socket size?

To select the correct PROTO Flex Impact Socket, match the socket size to the fastener head dimension—here, 11 mm for metric hex bolts. Ensure the drive size (3/8") fits your ratchet or impact wrench. The 6-point design reduces rounding on worn fasteners. For confined spaces, the flex joint provides angled access without sacrificing torque transfer.
