MILD STEEL ALLEN BOLT

Mild steel Allen bolts with hexagonal socket drive for high-torque fastening in machinery and assemblies.

Mild steel Allen bolts are designed for high-torque applications where strength and a secure fit are required. The hexagonal socket allows for easy use with a wrench or socket, even in tight spaces. Though they are less corrosion-resistant than galvanized options, they remain highly reliable in indoor and dry conditions. These bolts are ideal for machinery, automotive, and structural steelwork.
