Achieving consistent torque transfer in confined or deep-set fastener locations demands a reliable extension bar. The Draper Expert Extension Bar (SKU 16749) is a 1/2" square drive, 50 mm bar manufactured from chrome vanadium steel that has been hardened, tempered, chrome plated and polished, providing robust corrosion protection alongside long-term durability in demanding workshop environments. A knurled ring is machined around the body of the bar to deliver a secure, positive grip during use, reducing the risk of slippage when applying torque. Socket retention is handled by a spring-loaded ball bearing, which holds the attached socket firmly in place and prevents unintended disengagement mid-task — a practical advantage when working in awkward or overhead positions. The bar is manufactured and tested generally in accordance with DIN 3122 and ISO 3315 specifications, confirming it meets recognised dimensional and performance standards for square-drive extension equipment. Supplied as a single 1/2" square drive extension bar of 50 mm length, it forms a dependable addition to any professional socket set.
Expert Quality, manufactured from chrome vanadium steel hardened and tempered with a polished finish. Each ext. bar has a knurled ring for extra grip. Attached with a spring - loaded ball bearing for secure socket retention.
