Professional Applications & Engineering Value
Engineered for demanding panel mounting applications, the PEM® CLS-440-0 press-fit nut solves critical challenges in electrical enclosures, industrial controls, and electronic assemblies. The 18-8 stainless steel construction provides exceptional corrosion resistance where environmental factors threaten fastener integrity. The 4-40 UNC coarse thread configuration ensures rapid assembly while maintaining Class 2B thread fit precision for consistent torque performance. This round head press-fit nut eliminates the need for welding or adhesives, reducing installation time and labor costs while providing permanent threaded inserts in thin-gauge materials. The specialized design prevents rotation and pull-out under vibration, making it ideal for panel mounting in transportation, telecommunications, and heavy machinery applications.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with 0.25" head OD and 0.07" head height. Features 4-40 UNC coarse threads with Class 2B thread fit tolerance for optimal fastener mating. Compliant with RoHS 3 (2015/863/EU) environmental standards. Installation requires No. 19 drill bit (0.166" diameter) for panels with 0.03" minimum thickness. Right-hand thread direction follows industry-standard fastening conventions.
