Each fastener combines a standard hex nut with a serrated external tooth lock washer that bites into the mating surface under torque, resisting loosening from vibration and dynamic loads. The 1\/4-20 thread size makes this a high-volume fastener for light-gauge assemblies. The stainless steel construction provides corrosion resistance in wet, outdoor, and chemically exposed environments. These are installed by HVAC technicians, plumbers, electricians, and general contractors wherever a combined nut-and-lock fastener is needed in a single operation.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for residential and light commercial applications where vibration resistance and corrosion resistance are required simultaneously. Typical uses include equipment mounting, electrical panel work, conduit support, HVAC equipment brackets, and plumbing fixture attachment. The external tooth design is most effective on smooth, flat bearing surfaces where the serrations can engage fully. The 100-piece pack quantity is sized for service truck stocking and small-project needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated external tooth lock washer eliminates need for a separate lock washer during assembly\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion in outdoor, wet, and chemically exposed environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread size — one of the most common thread standards in trade applications\u003c\/li\u003e\n  \u003cli\u003eWidth across flats of 0.4375 inches accepts a standard 7\/16-inch wrench or socket\u003c\/li\u003e\n  \u003cli\u003ePack of 100 units supports bulk stocking for service vehicles and job sites\u003c\/li\u003e\n  \u003cli\u003eExternal tooth profile provides higher vibration resistance compared to internal tooth designs on smooth surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC hex nut replacement or new-installation fastener compatible with any 1\/4-20 threaded bolt or stud in residential or light commercial equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 7\/16-inch wrench or socket. Ensure the bearing surface is flat and clean so the external teeth can seat and engage properly — a rough or painted surface reduces locking effectiveness.
