GRMB

We manufacture and supply Hex Bolts in a wide range of diameters, from 6 mm up to 80 mm. Lengths are fully customizable based on client specifications. Ideal for heavy-duty industrial applications, our bolts are precision-engineered to deliver strength, reliability, and performance under demanding conditions. We support bulk orders and custom manufacturing to meet varied sector requirements.

Our Allen cap bolts feature a cylindrical head with a hexagonal socket for high-torque applications. The compact head design makes them ideal for limited-clearance assemblies requiring significant clamping force.

Our square head bolts provide exceptional torque resistance and are ideal for applications where a wrench must be used in confined spaces. The square head design prevents rolling when placed on a flat surface.
