Sealey SBH023 Hex Socket Bit 12Mm 1/2inSq Drive

The Sealey 1/2" Drive 12mm Hexagon Socket Bit is a substantial mid-to-large size that handles robust fasteners across automotive, engineering and construction applications. This 12mm socket is particularly common for larger brake components, suspension mounting bolts, engine bay fixings and heavy-duty machinery, where the increased size provides the necessary strength for higher torque applications. Manufactured from forged Chrome Vanadium steel with a hardened S2 steel bit insert, this socket is engineered to withstand significant torque loads whilst maintaining precise fastener engagement. The comprehensive heat treatment process maximises the material's hardness and durability, whilst the chrome plated finish with fully polished mirror surface ensures long-lasting corrosion resistance and professional appearance. The practical knurled ring feature provides enhanced grip even when working in challenging conditions with oily hands, crucial when applying significant force to stubborn f
