Professional Applications & Engineering Value
This 10-32 UNF serrated flange locknut delivers critical vibration resistance in demanding applications where secure fastening is paramount. The 18-8 stainless steel construction provides exceptional corrosion resistance, making it ideal for harsh environments including chemical processing, marine equipment, and outdoor machinery. The serrated locking feature beneath the flange bites into mating surfaces, creating permanent resistance to rotational forces that cause conventional nuts to loosen. Combined with the 1/2" flange diameter, this design eliminates the need for separate washers while distributing clamp load over a wider area, preventing surface damage to softer materials. The UNF fine thread configuration offers superior tension control in precision assemblies where vibration-induced failure is a constant concern.
Specification Summary & Compliance
This flange locknut features precision Class 2B thread fit with 10-32 UNF fine threads and right-hand thread direction. Manufacturing adheres to standard inch system specifications with external hex drive (3/8" width) and 7/32" height. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental safety and chemical restriction adherence for global industrial applications.
