Manufactured in the UK from 7075T7 Aluminium and hard anodised, our Race Spec Flanged Hex Head Bolts are measured from under the head. Our Race Spec range are drilled through the flats to allow for ease of lockwire, and the head are scooped for maximum weight saving. This version has a large flange diameter and is 70% lighter than steel originals - they are suitable for non/low stress applications. Please use the filters in the left bar to locate the fastener of your chosen thread, length and pack size. You can find additional product dimensional information in the product 'Specifications' Tab.
