McMaster 7196A143 Impact Flex Socket Adapter, US Origin, 1.5" Square Drive

Convert your impact socket into a flex socket to access fasteners from an angle. Also known as universal joints. These adapters are sturdy, so they’ll withstand the high torque and force of impact tools.

Compatible Retaining Ring ID — Adapters that list a compatible retaining ring ID require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.
