prelok tuflok 180

The Tuflok Blue Nylon patch when applied is permanently fused onto the screw thread of the parent component, and increases the prevailing removal torque, allowing the screw to be locked in any position upon assembly.

Tuflok 180 is a blue nylon patch permanently fused to the screw thread. This process provides excellent vibration resistance and torque performance for all applications requiring controlled loading and re-usability.

Tuflok is effective, whether or not the fastener is fully seated, making it ideal for applications where continual adjustment is required.

A. The Tuflok process consists of fusing the Blue Nylon 11 material onto a defined area of the male thread surface.
B. Upon installation into the female threaded component, the nylon material is compressed filling the axial tolerances
between the threads (1).
C. The Tuflok process creates a strong metal-to-metal radial loading on the flanks of the
mating thread forms (2), which provides the locking action.

Recommendations

Hole Preparation
In all cases the female thread of the mating components should have the lead thread de-burred or countersunk to avoid damage to the patch material.
Thread Preparation
To obtain optimum patch performance both male and female threads should be in accordance with class 6g/h (metric) or class 2 a/b (unified).
Finishes
Tuflok can be applied to most popular plated finishes, as well as polymer and organic coatings. .

Customer free issue components
Parts manufactured from non-ferrous material should be supplied free from any surface contaminants. Variations in material structure can effect heating capability of the part during processing, which may result in torque variation. High installation speeds can create galling of the threads affecting product performance.
Samples
Pre-production samples are evaluated and then processed free of charge
