Professional Applications & Engineering Value
This Grade 8 steel flange locknut delivers exceptional engineering value in high-vibration environments where fastener security is critical. The serrated locking flange bites into mating surfaces, creating permanent resistance to rotational forces in machinery, construction equipment, and transportation applications. The 1/2"-13 UNC coarse thread with Class 2B fit ensures reliable engagement even in challenging conditions, while the integrated flange design distributes clamping force over a wider area, reducing surface pressure and preventing material deformation. Manufactured from high-strength steel, this external hex drive locknut maintains its locking performance through repeated use cycles, making it ideal for maintenance-critical industrial assemblies where vibration-induced failure is not an option.
Specification Summary & Compliance
This flange locknut features 1/2"-13 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring proper clearance for reliable assembly. The Grade 8 material certification provides 150,000 psi minimum tensile strength meeting ASTM A563 specifications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, with dimensional accuracy maintained through 1 1/32" flange diameter, 3/4" width across flats, and 29/64" height tolerances suitable for industrial applications.
