The elora 15 piece 3 4 drive bi hex socket set imperial is a professional grade socket set designed for heavy duty automotive and industrial applications requiring imperial sizing. Manufactured from chrome vanadium steel, this comprehensive set provides the strength and durability demanded by professional mechanics and engineers working with larger fasteners. Each socket is hardened and tempered to withstand high torque applications, then chrome plated to provide long lasting corrosion protection. The bi hexagon design offers superior grip on fastener flats, reducing the risk of rounding and making these sockets ideal for removing seized or corroded bolts on commercial vehicles, agricultural machinery, and heavy plant equipment. The set includes a reversible ratchet with push through coupler for quick socket changes, along with a 400mm extension bar for accessing recessed fasteners and a sliding t bar for additional leverage when breaking stubborn fixings. All components are housed in a heavy gauge steel storage case that protects your investment and keeps the workshop organised.
