Prevailing Torque Locking Tuflok®


In every case where a clamping, reusable threadlocking is required, pre-coating with Tuflok® is exceptionally suitable. This means that additional security methods become superfluous. Tuflok® has proved itself successfully worldwide in the automotive, mechanical- engineering, hydraulic, window-construction and electrical-engineering industrial sectors. It can also be used where other systems fail for technical or economic reasons.

Tuflok® 180 (Blue Patch) is a vibration-reduced, partial coating of nylon, which is melted permanently onto the threaded component. This process produces exceptional vibration protection and excellent torque stability in all applications. Tuflok® is ideally suited for applications where continuous adjustments are necessary.

Tuflok® 360 is applied on the entire threaded part circumference and is suitable for applications where a reusable sealing against liquid or gas is required. You can find the same specifications here as in case of Tuflok 180 (Blue Patch).

Function description



The required clamping effect is achieved by screwing into a nut or a specific component. While screwing, the nylon is compressed. The radial tension created by the elastic deformation of the product causes a retaining by the increase of friction.



The effect is achieved where the axial clearance between the bolt and nut or specific component is filled with TUFLOK® (1). This TUFLOK® process generates a strong metal-to-metal radial load on the flanks of the nut or specific component, which causes the screw locking (2).

Characteristics



Product characteristics



• High protection effect
• Vibration-resistant in every position, also particularly suited as an adjusting screw.
• Seals against gases and liquids in case of all-round coating
• Replaces secondary securing elements (washers etc.), which are often forgotten during installation or which get lost
• Reusable repeatedly
• No hardening time; can be loaded immediately
• Suitable for all metallic materials and rustproof steels, aluminum and brass

Installation and coating



This installation of the pre-applied bolts can be implemented by machine or manually with traditional tools. By means of a fully-automated supply system, productivity is increased.

The bolts or component parts to be coated should be oil- free and grease-free as far as possible. It is not required as mandatory, however, torque values are reduced as a result.
