Professional Applications & Engineering Value
These 18-8 stainless steel press-fit studs solve critical challenges in electronics enclosures, machinery panels, and precision instrument assembly where vibration resistance and corrosion protection are paramount. The fully threaded 4-40 UNC coarse thread design maintains consistent torque retention while the precision press-fit installation eliminates loose hardware in thin sheet applications. Engineered for 0.111" holes with minimal clearance, these studs prevent rotation and pull-out under dynamic loads, making them ideal for high-reliability assemblies requiring repeated disassembly. The Class 2A thread fit ensures compatibility with standard nuts and tapped holes, streamlining production while the right-hand thread direction facilitates conventional installation tools.
Specification Summary & Compliance
Manufactured to inch system specifications with 0.191" base diameter and 1" length. Features Class 2A thread fit per UNC standards with 29/32" thread length. Compatible with No. 34 drill bit for 0.111" hole preparation. Compliant with RoHS 3 (2015/863/EU) environmental directives. PEM® part number FHS-440-16 identifies this fully threaded, right-hand thread configuration designed for precision industrial applications.
