Permalok Fastening Systems Ltd has been stocking and supplying high quality vibration resistant engineered fasteners to a variety of industries for many years. We particularly specialise in fasteners for railway infrastructure, but we also supply fasteners for construction applications and machinery. Permalok is the only place in the United Kingdom where you'll find Huck Lockbolt fastening systems manufactured by Huck International Ltd, and MolaBolts manufactured by Advanced Bolting Solutions Ltd. We have the necessary industry experience and technical know-how to offer expert advice on all of the fastening solutions we provide across many industries, in both new build and maintenance.

As well as offering a wide range of fasteners for multiple applications, Permalok also provides a variety of useful services. We'll send an engineer/consultant to your site to advise on the most appropriate fastener for your application; we’ll even install Huckbolts as samples for testing and analysis. Not only does Permalok advise and supply, but we also install your chosen Huckfasteners for you. Expert engineers will ensure the work is carried out correctly and safely, meaning you won't need to redeploy your own staff from other imperative work. But if you're happy to do the job yourself, Permalok is pleased to make available all types of Huck tooling for purchase. In addition to the tools themselves, we have a large stock of maintenance spares. If you would rather not purchase brand new tools, Permalok also offers a large range of hire tools, both hydraulic and pneumatic. These are available for long and short term hire. Because we are the only Huck approved 'Centre for Excellence for Tooling' in the United Kingdom, we can offer an unbeatable repair and service facility for pneumatic tools, hydraulic tools and power packs, all at our dedicated workshop in Doncaster.

We'll ensure customer downtime is kept at a minimum by offering a fast turnaround and replacement tools to maintain production. Last but by no means least, Permalok provides training for installation procedures for all Huck products, enabling effective, safe and efficient handling of equipment.

So for a wide range of vibration resistant lockbolts, blind fasteners and MolaBolts - as well as the appropriate installation tooling - the Permalok Fastening Systems Ltd website is the only place to be.
