The siegen 9 piece combination drive socket extension bar set provides professional coverage across 1 4 , 3 8 , and 1 2 square drives, giving tradespeople a comprehensive range of extension lengths for socket work in confined and open spaces alike. Each bar is forged from chrome vanadium steel, then heat treated and chrome plated to a mirror finish for lasting corrosion resistance and durability. The wobble feature on the cut-away tips allows sockets to be driven with a shaft offset of up to 10 , making it easier to reach fasteners at awkward angles without the need to reposition. Spring-ball socket retainers keep sockets securely seated during use, while deep knurling along the shafts provides a positive grip when spinning off fixings by hand. The full set is supplied in a moulded eva foam storage tray, keeping all nine bars organised and protected between jobs. A lifetime guarantee is included for added peace of mind.
