Alloy and steel hot forged fasteners
In our production facilities, we carry out specialist hot forging of high nickel alloys and stainless steels.
Our four hot forging presses produce high-quality controlled forged fasteners using Pyrometer technology and customised techniques for induction-forging.
Our forged fasteners are in the standard range between ¼in and 2in for imperial fasteners; with metric fasteners, it is between M5 and M52.
With forged fasteners, the standard length ranges from 10mm-500mm long under the head fastener's head, depending on the diameter.
Forging facilities, machining and hydraulic presses
Our production facilities contain a vertical machining centre, a number of CNC lathes, and sliding head machines.
In addition, we also have machines for drilling, milling, finishing, and component cleaning; conventional and automatic lathes, and CNC bandsaws.
The identity of items can be obtained through material grade, cast number and the manufacturer's initials.
In our factory, we can reground and modify tools such as chaser dies, drills and taps. The mechanical press tooling is also produced in-house.
