{"product_id":"m20-nylon-insert-nut-din-985-a2-stainless-steel","title":"M20 Nylon Insert Nut DIN 985 A2 Stainless Steel","description":"\u003cp\u003eThis M20 nylon insert lock nut is manufactured to DIN 985 in A2 stainless steel (304 grade). DIN 985 specifies a hexagon nut with a nylon collar set into the top face, for joints subject to vibration. Property class A2-70 indicates a minimum tensile strength of 700 MPa - stronger than standard A2-50 and suited to structural fixings where higher clamping force is needed. The nylon collar is undersized and deforms around the thread as the nut is run on, gripping it and resisting loosening under vibration without damaging the bolt thread.\u003c\/p\u003e\u003ch3\u003eTypical applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJoints exposed to vibration or cyclic loading\u003c\/li\u003e\n\u003cli\u003eMachinery, pumps, and rotating equipment\u003c\/li\u003e\n\u003cli\u003eVehicle, trailer, and marine assemblies\u003c\/li\u003e\n\u003cli\u003eAny fixing that must not shake loose\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAvailable in packs of 20 to 100, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.
