Professional Applications & Engineering Value

This 18-8 stainless steel press-fit nut delivers exceptional engineering value in applications requiring secure panel mounting where traditional fastening methods prove impractical. The press-fit installation eliminates the need for welding, tapping, or additional hardware, significantly reducing assembly time and labor costs. The round head design with 0.5" OD provides optimal surface contact for uniform pressure distribution during installation, preventing panel distortion in thin materials. Engineered for electronic enclosures, control panels, and machinery guards, this component maintains thread integrity even in high-vibration environments, ensuring long-term fastening reliability without the risk of cross-threading commonly associated with conventional nuts.

Specification Summary & Compliance

This precision press-fit nut features 5/16"-18 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring consistent thread engagement and interchangeability. The inch-system component maintains dimensional accuracy with head height of 0.23" and head OD of 0.5", engineered for installation in panels with minimum thickness of 0.125" using Z drill bit (0.413" diameter). The product is RoHS 3 (2015/863/EU) compliant and manufactured to PEM® quality standards for reliable performance in industrial fastening applications.
