Professional Applications & Engineering Value

This 1/4"-28 UNF flange nut is engineered to address common industrial challenges like vibration loosening and corrosion. The 18-8 stainless steel material provides excellent durability in moist or chemical-exposed settings, while the fine UNF threads and Class 2B fit offer tight, secure connections that resist shaking in machinery, automotive, and construction assemblies. The integrated 5/8" flange acts as a built-in washer, distributing clamp load evenly to protect soft surfaces and reduce the need for additional components. With an external hex drive for quick tool engagement, it streamlines maintenance and reduces downtime in heavy-duty applications.
