The nylon insert is positioned in a tapered section located at the back end of the nut. When you install a nylon lock nut onto a threaded stud or bolt, the nylon insert wraps tightly around the threads and locks the nut in place.\u003c\/p\u003e\n\u003cp\u003eThis gives a nylon lock nut a distinct advantage over a regular lock washer in terms of hold integrity - especially when the bolt or stud is subject to vibration.  The nylon lock nut is unaffected by vibration and provides a more secure hold.\u003c\/p\u003e\n\u003ch4\u003e\n\u003cbr\u003eHow to use a Hex Lock Nut:\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eThread the lock nut onto the bolt and turn the nut clockwise until it no longer turns.

For a given nut size of nominal diameter, Unified Fine Pitch (UNF) and Unified Coarse Pitch (UNC) represent two different thread densities.  UNC is the most commonly used.  The choice of UNC versus UNF is influenced by the specific application of the job at hand and each type delivers different advantages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUNC \u003c\/strong\u003e- coarse threads are more durable and have greater resistance to stripping and cross-threading. They are also less susceptible to being nicked or damaged and therefore they do not have to be \"handled delicatley\" compared to fine thread (UNF) nuts.  Coarse nuts install much more quickly and are not not affected by plating buildup to the same extent as fine UNF threads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUNF\u003c\/strong\u003e - fine threaded bolts are stronger than UNC coarse threaded bolts of the same hardness.  This is due to the fine threaded bolts having a slightly larger tensile stress area.  Fine threads also have less tendency to loosen under vibration due to the fact that they have a smaller helix angle than coarse threads. \u003c\/p\u003e\n\u003cp\u003eUNF also has the advantage of allowing for finer adjustments in applications that require this characteristic.  They can also be more easily tapped into difficult to tap materials and thin walled sections and they require less tightening torque to achieve equivalent preloads to the corresponding UNC nuts\/ bolts.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eShop Today!\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Grease Monkey Direct","offers":[{"title":"1\/4\" (Qty 50)","offer_id":56764479963522,"sku":"GT-NUT30","price":1.85,"currency_code":"GBP","in_stock":true},{"title":"5\/16\" (Qty 50)","offer_id":56764479996290,"sku":"GT-NUT31","price":2.95,"currency_code":"GBP","in_stock":true},{"title":"3\/8\" (Qty 50)","offer_id":56764480029058,"sku":"GT-NUT32","price":4.4,"currency_code":"GBP","in_stock":true},{"title":"7\/16\" (Qty 25)","offer_id":56764480061826,"sku":"GT-NUT33","price":2.65,"currency_code":"GBP","in_stock":true},{"title":"1\/2\" (Qty 25)","offer_id":56764480094594,"sku":"GT-NUT34","price":4.9,"currency_code":"GBP","in_stock":true},{"title":"5\/8\" (Qty 10)","offer_id":56764480127362,"sku":"GT-NUT35","price":3.45,"currency_code":"GBP","in_stock":true},{"title":"3\/4\" (Qty 10)","offer_id":56764480160130,"sku":"GT-NUT36","price":5.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1359\/2999\/files\/nylonlockingnuts_fcfd9c5b-ef37-4a85-9d25-99b7fb85857b.jpg?v=1783941168","url":"https:\/\/greasemonkeydirect.co.uk\/products\/imperial-unf-nylon-locking-nuts","provider":"Grease Monkey Direct","version":"1.0","type":"link"}
