RS PRO 1/4 in Square Drive Extension Bar Socket, 100mm Overall Length 912-5423

RS PRO 912-5423 is a 1/4 in square drive extension bar socket with a 100mm overall length, designed to provide additional length and torque when tightening or loosening nuts and fasteners. Manufactured from high-quality chrome vanadium steel, it combines excellent mechanical strength with robust resistance to rust and corrosion, ideal for demanding industrial environments.

The extension bar features a matt finish for enhanced wear protection and aesthetics. Its square drive ensures compatibility with standard 1/4 in sockets, while the spring-loaded ball bearing secures the socket firmly, eliminating wobble and reducing risk of slipping during use. With robust detent notches, it locks tightly onto ratchets and breaker bars to maintain a secure hold.

The knurled grip on the extension shaft provides a textured non-slip surface, enabling users to apply extra torque by hand or quickly remove loosened fasteners. This product is suitable for a broad range of industrial, construction, automotive, and maintenance applications where access to confined or recessed fasteners is required.
