Professional Applications & Engineering Value
This zinc-plated steel press-fit stud solves critical challenges in sheet metal assembly where vibration resistance and permanent mounting are essential. The fully threaded 5/16"-18 UNC design maintains consistent thread engagement across the entire 1-1/4" length, preventing loosening under dynamic loads. Engineered for 0.311" hole diameter applications, the stud's 0.391" base diameter creates an interference fit that eliminates the need for welding or adhesives. This Class 2A thread fit ensures compatibility with standard nuts while the coarse thread spacing provides rapid installation in production environments. Ideal for electronics enclosures, machinery frames, and automotive components requiring reliable fastening solutions with minimal installation tools.
Specification Summary & Compliance
This precision steel press-fit stud features 5/16"-18 UNC coarse threading with Class 2A thread fit per ASME standards. Manufactured to exacting tolerances for 0.311" hole diameter with 0.000" to 0.003" hole size tolerance. The product is fully RoHS 3 (2015/863/EU) compliant and meets PEM® engineering specifications for press-fit applications requiring 1-1/4" length and 0.093" minimum material thickness.
