Allen & Hexbolts
Allen Bolts
An Allen bolt, also known as a Socket Head Cap Screw, has a circular head with a hexagonal socket in the centre. It is tightened using an L-shaped hexagonal key, commonly known as an Allen key.
Allen bolts are typically made from high-strength steel and are used where a secure and precise fastening arrangement is required.
Hex Bolts
A hex bolt has a head with a six-sided outer surface and is tightened using a spanner or similar tool. Hex bolts can be manufactured from different materials, including various types of steel, metals, and plastics.
The choice of material and bolt configuration can be based on the requirements of the particular application.
