- Hex Nyloc Insert nuts is hex shaped, internally threaded with a nylon insert. The nylon material prevents loosening from vibration and cross threads to stop the nut from backing off of the fastener. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut in two ways. First, it forces the bottom face of the screw threads against the top face of the nut threads, increasing the friction between the two. Second, the nylon applies a compressive force against the screw itself. They can also be used to assist sealing the bolt thread against seepage of oil, water, petrol, paraffin and other liquids.They come in a variety of materials
- Also known as: Nylon Insert Nut, Nylon Lock Nut
- Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shinny bright silver finish. A thin layer of zinc is applied by either electroplating or mechanically. It is intended to be used internally. Whilst some people use it externally it isnt recommended if corrosion is a concern. If you want a fastener that will withstand the outdoor elements choose from our Stainless steel range
- What does TPI stand for?: TPI stands for “threads per inch” which literally means the number of threads within each inch on a nut, a bolt, or a fastener. To determine the TPI of a nut, either count the number of threads contained within an inch of length on the male fastener or use a thread checker. If the male fastener is less than an inch, measure 1/2", count how many there are then multiply the number by 2
- Difference between UNC v BSW Threads: UNC and BSW have the same thread per inch value, except for the 1/2" size. Theoretical it would be possible to interchange them as they have the same amount of threads per inch. However due to the difference in thread angle, the connection would not be as strong as when using the proper combinations
