Nylon Insert Lock Nuts are an excellent fastening choice for applications requiring strong vibration-resistant mechanical connections. They outshone traditional nuts by offering improved resistance to loosening and protecting bolt threads from damage - here are five reasons to use nylon Insert Lock Nuts on your next project:
Nylon insert lock nuts (commonly referred to as "nyloc nuts") feature hex nuts with collars filled with special nylon that is smaller than their thread diameter, creating friction when tightened - this prevents loosening caused by vibration or thermal cycling, two factors that could otherwise lead to regular hex nuts becoming loose over time.
Hex lock nuts with nylon inserts differ from metal-based locking nuts in that they contain non-metallic materials that create friction; as a result, these non-metal components are more temperature and chemical sensitive, making them safer choices for projects exposed to harsh environments.
Nylon hex lock nuts are designed to prevent loosening due to vibration or dynamic loads, while also serving in high-temperature applications where regular hex nuts may become damaged or warp under stress. Their nylon insert adds more friction between its threads and those of the bolt threads than an all-metal version, making it harder for it to back off of the screw and back off completely.
Hex lock nuts equipped with nylon inserts are an efficient, cost-effective and more secure alternative to safety wire or chemical adhesives that require extra steps during installation and removal. Plus, they create more secure connections than traditional lock washers while being suitable for industrial projects requiring vibration-resistant hardware.
Hex lock nuts with nylon inserts offer greater wrench clearance in limited spaces, enabling users to apply a higher torque with less effort and save time in assembly processes. Furthermore, they can even be installed into blind holes without having to add an additional washer for thread engagement purposes.
Hex lock nuts with nylon inserts offer many advantages over their non-nylon counterparts, with their ability to remain tight even when tightening at very low angles. This means they can be applied safely to angled fasteners without fear of loosening; making them suitable for applications on airplanes, aircraft, calculators, electronic computers and radio equipment which require secure, durable connections.
As it's essential that hex lock nuts only be reused once their service life has expired, repeated removal and reinstallation could weaken their locking strength over time. While this should not pose an issue in applications that do not involve frequent tightening/loosening cycles of their fasteners, reuse should be avoided when they may be exposed to extreme levels of vibration or shock loading.
