Professional Applications & Engineering Value

This 316 stainless steel nylon insert locknut delivers critical vibration resistance where conventional fasteners fail. The nylon insert locking mechanism creates consistent friction against mating threads, maintaining clamp load in high-vibration environments like machinery, transportation equipment, and structural assemblies. The UNC coarse thread design provides rapid installation while the Class 2B thread fit ensures reliable engagement without binding. Manufactured from corrosion-resistant 316 stainless steel, this locknut withstands aggressive environments including marine, chemical processing, and outdoor applications. The 220°F temperature rating makes it suitable for engines, pumps, and industrial equipment where thermal cycling occurs. These engineering features combine to prevent catastrophic loosening while providing long-term reliability in demanding industrial applications.

Specification Summary & Compliance

This locknut features 3/4"-10 UNC coarse threads with Class 2B thread fit per ASME standards, ensuring proper clearance and engagement. The external hex drive measures 1-1/16" across flats with a 7/8" height profile. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming restriction of hazardous substances. The nylon insert locking element maintains performance within specified temperature ranges while the 316 stainless steel construction provides corrosion resistance matching industry standards for critical fastening applications.
