A worldwide reputation


WIRELOCK® is the invention of John Dodd – chairman and founder of Millfield Enterprises (Manufacturing) Ltd. John combined his passion for chemistry with an interest in the UK mining industry which was then a major part of the NE England’s industrial landscape. The mines were looking for a product that would eliminate the hazards of working with molten metal and produce a void free socket. The result of his research and drive was the manufacture of WIRELOCK® – the original cold socketing compound which was successfully launched in the UK mining industry in 1963.


Over 50 years on, WIRELOCK® has required no reformulations since its conception and is the premier cold socketing compound distributed worldwide and used across five industrial sectors namely bridges, structures, off-shore, mining and general engineering. WIRELOCK® is manufactured in the UK to ISO 9001: 2015 and meets the requirements of ISO17558 and DNV-OS-E304 and has Type Approval from ABS, DNV and Lloyds. To maintain our position in the market place we continue to have strong links with Universities and industry bodies.

The WIRELOCK® brand has developed other variants to meet customer requirements – WIRELOCK® SLING, PARALOCK®, Umbilical Terminations.


WIRELOCK® has a trusted proven track record spanning over 50 years’. Here at WIRELOCK® we know and understand resins and curing systems but in addition we know about ropes and all aspects of rope terminations – the result is that our technical service is unrivalled and comes as part of WIRELOCK’s customer service.


WIRELOCK® is produced and manufactured at our modern custom-built factory in Newburn, Tyneside in the UK. Excellent transport links to A1M, A19 and Newcastle Airport.
