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.

Here’s an example of our fastener manufacturing capabilities, which shows that not all our fasteners are threaded.

These 106mm x 220mm drilled pins were manufactured on a CNC machine in our onsite machine shop.

The above picture shows the pin inside the CNC machine during manufacturing.  A hole is then drilled into the pin to accommodate an R Clip.

We have extensive fastener manufacturing capabilities and many years of experience in providing high quality fastener solutions.  As well as CNC machining, we offer extensive forging and threading solutions to meet your needs.

Alongside our special fastener manufacturing capabilities, we hold large stocks of finished bolts in metric and imperial threadforms.

We also carry an extensive range of bolt blanks, enabling us to rapidly meet your needs, however complex.

We can also perform chemical and mechanical testing in-house via our well-equipped quality control department.

Contact us to discuss any requirements you may have and we’ll be happy to help.

Mach 12 Machine Tool Exhibition

The Mach 12 exhibition at the NEC is held every two years to showcase the machine tool industry and associated products.

The global, quality, and precision aspects of this industry were demonstrated by the number of Formula 1 cars on display.

Machining is an important secondary function that is of significant importance to us, especially when manufacturing specials.

Useful contacts were made with tooling and quality equipment suppliers.

Visit to Wire 2012 Exhibition, Dusseldorf

We visited the bi-annual Wire & Tube exhibition which was held in March 2012 in Dusseldorf, Germany.

Hall 15 housed the large display of fastener machinery and associated suppliers.  This exhibition prides itself in being the most important of its type in Europe.

On the Nedschroef stand, they were featuring the latest generation of high speed multi-station cold forging machines.  The machine pictured below is the Nedform 6-die cold former.

The machine was set up to produce both the washer and the spline shaft which are illustrated in the pictures below.

The parts are complicated enough to produce yet the time witnessed to change from the one to the other was less than 5 minutes – truly amazing!  This speed of change is made possible by the computer and electronic controls featured on this machine.

A number of new manufacturing ideas were noted and contacts were made, which will ensure that our production capability is at the top of its class.
