Professional Applications & Engineering Value
This 18-8 stainless steel press-fit nut solves critical challenges in panel mounting and thin sheet metal assembly applications. The press-fit installation method eliminates thermal distortion risks associated with welding and provides consistent thread engagement in materials as thin as 0.03". The 2-56 UNC coarse threads with Class 2B fit maintain reliable performance in high-vibration environments common in electronics enclosures, control panels, and aerospace components. The corrosion-resistant stainless steel construction ensures durability in demanding conditions while the round head design prevents installation rotation, making it ideal for automated assembly processes.
Specification Summary & Compliance
This press-fit nut features 2-56 UNC coarse threads with Class 2B thread fit tolerance, ensuring precise engagement with mating components. The inch system measurement provides 0.25" head OD and 0.07" head height for standardized installation. Manufactured to PEM® specifications for 0.03" minimum panel thickness with No. 19 drill bit (0.166" diameter) compatibility. The product is fully RoHS 3 (2015/863/EU) compliant and meets industry standards for right-hand thread direction and press-fit fastener applications.
