Proto J5270AB Socket Drive Adapter 3/8 in 2 in Oal

Product Description

The PROTO J5270AB is a 3/8 inch drive-to-3/8 inch socket adapter built for professional-grade hand tool applications. With a 2 inch overall length (OAL), this adapter allows technicians to connect drive tools and sockets in matching 3/8 inch drive configurations, providing extension reach or directional flexibility at the drive interface. It meets ANSI Spec B107.1 and Federal Spec GGG-W-641e, confirming it is built to recognized dimensional and performance standards. The J5270AB is backed by a manufacturer lifetime warranty, making it a reliable long-term addition to a professional tool kit.

This adapter suits trade professionals across HVAC, plumbing, electrical, and mechanical service work where 3/8 inch drive ratchets, torque wrenches, or impact tools are in regular use. The 2 inch OAL provides modest reach extension without significantly altering torque feel. It is well suited for tight-access fastener work on equipment panels, pipe fittings, and electrical enclosures where a direct socket-to-ratchet connection is not practical.

• Meets ANSI Spec B107.1 and Federal Spec GGG-W-641e

Compatibility

Installation Notes

This adapter is installed and removed by hand — no special tools required. Ensure the drive square engagement is fully seated in both the drive tool and socket before applying torque. Inspect the adapter for wear or deformation before each use, particularly in impact applications. Follow applicable workplace safety and tool-use guidelines for hand tools.
