Inlex Locking Ltd

UK Leaders in Threadlocking & Sealing Technology

Inlex Locking Ltd is the UK’s leading threadlocking and sealing specialist, based in Wolverhampton.

 

We offer a comprehensive range of threadlocking and sealings for high-tech fastening applications across many industries.

 

These advanced products are applied by robotic and bespoke automated equipment, involving state-of-the-art technology.

Versatile Solutions

Microencapsulated adhesives and non-reactive thread and underhead sealing systems are used at Inlex. Nylon thread locking and non-reactive thread sealants provide a cost-effective solution to the perennial problems of sealing metal-to-metal joints, without affecting their integrity.

The latest technology employed enables duplex patches to be applied. This means two different products can be applied on the same fastener or, if required, a single application of the same material on both thread and underhead.

Rimlex®

Rimlex® sealants provide a cost-effective and high-quality peripheral seal, which can be applied to the underhead bearing surface of bespoke fasteners and other components.

 

It can replace copper, aluminium and other more expensive sealing washers.

 

Rimlex® can be pre-applied, away from the assembly area, ensuring the correct amount is dispensed for robust and consistent joints.

Other Threadlocking and Sealing Systems

Sealing systems such as precote® 5 and 15, and Microseal 204 prevent a range of potential problems. These include water ingress for sealing on fluid tanks and roof channels in ambient and elevated temperatures.

 

Our reactive locking systems include popular products such as precote® 30, 80 and 85. Nylon 11 torque patch systems in blue, red and bespoke colours are also available. These products can be applied to most substrates and commercial finishes. They are currently specified by major OEMs in the automotive, defence and other industries.

 

At Inlex, we also specialise in the selective application of lubricants for pre-applied, dry-to-touch patch systems, including Top 300.

Exclusive Patching Partnership

We have further enhanced our capabilities by securing an exclusive partnership with patching giant Nylok.

As the sole license UK holder for Nylok’s Tuflok®, NySeal® and NySeal 2.0® patching systems across the UK. In addition our Poland and Czech Republic facilities also hold a licence to apply Nylok’s Tuflok®, meaning we can apply some of its most popular and innovative solutions.

Plating, Patching & Inspection

Inlex also specialises in automatic inspection of fasteners: from inspecting for non-conforming products and contamination, to automatic crack detection.

With its sister company WEP, Inlex provides a unique ‘one stop shop’: plating, patching and inspecting fasteners for manufacturers and users.

Value-added services like packing and assembly are also available. So from a specific project to a full end-to-end service, contact our sales team for a bespoke solution to your problem.

Services & Coatings

We offer a wide range of services and coatings each delivering advanced surface finishing solutions for critical components and complex supply chains.

Nylon Locking Patch

Nylon patches prevent fastener loosening from vibration, offering reusable, durable locking for industrial applications.

Optical Sorting

Optical sorting inspects fasteners for defects, ensuring accuracy, speed, and reduced labour in bulk processing.

Reactive Locking Patch

Pre-applied adhesives offer strong, single-use thread locking with precise placement and reduced assembly time.

Sealants

Thread and underhead sealants ensure reliable, reusable sealing with environmental benefits across diverse fastener applications.

Thread Protection & Masking

omniMASK® provides durable thread masking for nuts and bolts, resisting weld spatter and coatings.

Wax Based Thread Lubricants

Wax coatings reduce friction, noise, and torque, enhancing fastener performance in specialised industrial applications.

Accreditations

Inlex Locking Ltd has vast experience and knowledge within the coatings sector, backed by a comprehensive array of relevant quality accreditations and awards.
