The sealey premier black socket extension bar set is engineered from heat-treated and hardened chrome vanadium steel, delivering exceptional durability for demanding professional applications. The fully polished black chrome finish provides superior corrosion resistance, whilst machined and lacquered heads ensure long-lasting performance in even the toughest workshop environments. Designed with practicality at its core, the wobble feature allows sockets to be driven with the shaft offset at up to 10 , enabling access to awkward fasteners in confined or restricted spaces. Spring-ball socket retainers keep sockets securely attached during use, and deep knurling on each shaft provides a confident, reliable grip whether working with oily hands or wearing gloves. Supplied in an eva foam storage tray for convenient organisation and backed by a lifetime guarantee.
