12 Point Flange Bolts

We supply 12 point flange bolts in UNF and UNC thread forms manufactured from high strength self colour steel. The 12 point head design allows increased torque application while providing a reduced head diameter compared to standard hex bolts.

Commonly used in engineering, performance automotive and high-load assemblies, these bolts provide secure clamping and reliable fastening. Available in a range of imperial sizes with fast UK delivery.
