The VALUE COLLECTION R-34820-3/4 is a heavy hex lock nut with a nylon insert, designed for threaded fastening applications requiring reliable vibration resistance. The nylon insert collar deforms against the bolt thread to create a prevailing torque locking action, holding the nut in place without the need for additional locking hardware. Made from Grade 2 steel in an uncoated finish, this nut is sized for 3/4-10 UNC right-hand thread and measures 53/64 inches in height with 1-1/4 inches across the flats. It is suitable for general-purpose mechanical assembly where moderate strength and reusable locking performance are required.
This heavy hex lock nut is used in general industrial, structural, and mechanical assembly applications where a 3/4-10 UNC thread fastener is specified. The heavy hex profile provides a larger bearing surface than standard hex, making it well suited for bolted connections in steel fabrication, equipment mounting, and maintenance work. It is installed by hand and tightened with a standard wrench or impact tool. Minimum order quantity is 5 pieces.
Designed for use with 3/4-10 UNC right-hand threaded bolts and studs in general industrial and mechanical assembly applications.
Installation is performed by hand-threading onto a compatible 3/4-10 UNC bolt or stud, then torquing to the specified fastener assembly requirement using an appropriately sized wrench or impact driver. Power down or de-energize any connected equipment before servicing fastened assemblies. The nylon insert is rated for moderate temperature environments; verify service temperature limits before use in elevated-heat applications. Do not reuse nylon insert lock nuts in safety-critical joints where locking performance cannot be confirmed after removal.
