At Universal Boltforgers, we are here for all your fastener needs offering a total capability in hot forged bolts and associated components.

If a product is not readily available 'off the shelf', we have the facilities to make any shape and size of fastener in most grades of material, in most types of thread and in any type of protective coating and finish.

In addition to bolt forgings, we also manufacture hot bent bar, flattened and pierced bars and shaped billets for subsequent machining.

We have longstanding relationships with material stockholders and specialist providers of protective coatings, heat treatment and stainless steel cleaning services. Our network of strategic partnerships with local suppliers allows us to offer a fast, efficient response.
