John and Tim were kept busy with visitors who represented a good cross-section of the British fastener distribution industry. Great interest was shown in our non-standard Metric range and the special bolting that is produced in our factory, alongside the new ranges of fasteners in stainless, non-ferrous and exotic materials made possible by our expansion in 2016.

Special Fastener Manufacture – M12 x 505 Hex Bolts 8.8 BZP

long bolts, m12 x 500, special bolts, bolt manufacture

Our expertise in the manufacture of special and difficult to manufacture bolts was recognised and we produced the bolts pictured above for use by a multinational manufacturer of offroad vehicles.

The bolt illustrated above is M12 diameter x 505mm long, which was forged in our factory and then heat treated to achieve the mechanical properties grade 8.8. Due to the relatively small diameter and the long length of more than half a metre, distortion of the bolt shank is inevitable during the heat treatment process.  This required us to check and 100% rectify the batch using a hydraulic press, which is a skilled operation.

The final operation involves a zinc plating process which provided the anti-corrosion properties that are required for the application.

For further information, contact our experienced technical sales staff and we’ll be happy to discuss your requirements.
