Reverse Engineering

Reverse Engineering of Old or Obsolete Special Fasteners

Hague Fasteners are experts in the Reverse engineering (or Back Engineering) of all types of Engineered Special Fasteners, fixings and turned parts.

We have seen a sharp increase in the need for identification, reverse design and manufacturing of all sorts of components. Often in very small batches such as 2pcs, 10pcs, 25pcs etc. where the component has been in use for many years and there is no longer access to the original parts’ Engineering drawing.

Bespoke Reverse Engineered Fasteners

Often the items are completely Bespoke Fasteners that need making exactly to the dimensions and thread sizes of the existing part.

Reverse Engineering
From Old To New

Hague Fasteners also offer modifications to the parts where required. This is often an increase in material strength or a material upgrade for extra performance and reliability or simply a slight modification to certain sizes. Perhaps increasing the length or changing the thread form.

Engineering Rebuild and Repairs

Our special Fastener reverse engineering service is utilised by companies large and small where old plant or vehicles are being repaired or rebuilt. We are also at hand to assist enthusiasts who are working on private vehicle projects where a part is needed, perhaps some new head studs, or some extended Wheel Studs for a classic car or race car modification.

We are also proven to manufacture very small batches of items that may even be available from other Countries. Our reverse engineered Fasteners offer a UK Manufactured solution cheaper and faster than seeking an overpriced import where the rarity of the product required sees an over inflated price at the expense of the purchaser.

Where a special component is required and their is no access to a drawing or technical design description, Hague Fasteners operate a convenient solution.

1. You obtain a quotation from a photograph, so no need to lose time and money by sending the item in. We just ask that the item is photographed alongside a tape or rule so that we can establish rough sizes and costings to reproduce. 

2. We will then send you our formal quotation for reverse engineering the part. 

3. If you are happy with the proposed offer you then send in the sample (or we can collect if inconvenient due to component size). We then get to work replicating the item required with a lead time to suit your needs. 

We look forward to hearing from you with any requirements you have for replacing older or difficult to obtain Fasteners.

Unrivalled experience in manufacturing Fasteners to Clients designs. Total Customer Focus & Ethics make Hague Fasteners Limited, Special Bolting UK stand out from the crowd.

The Change Has Started

Since 1971 we have adapted, improved and continually listened to our Customers. 

It is their opinion and satisfaction that drives us to ensure we offer the very best level of Customer Service. 

You will find from quotation through manufacture, from supply to accounts & payment we strive to ensure no obstacles are in your way, assuring you a memorable service and a quality product every time.


One recurring source of frustration during recent Customer feedback analysis showed disappointment at the time taken to quote enquiries. Often next day quoting, whilst faster than the general industry norm for manufactured costings, is simply not fast enough.

We are proud to boast a significant improvement in 2014, in the handling of incoming RFQ’s & hope we can demonstrate to you the rapid response now enjoyed by our clients.
