- Robust thread engagement through fully threaded UNC coarse design and Class 2A fit for secure fastening
- Versatile material compatibility supporting minimum 0.04" material thickness and 7/32" edge distance requirements
- Regulatory compliance assurance with RoHS 3 (2015/863/EU) conformity for global manufacturing applications
- Optimized right-hand threading for standard tool compatibility and simplified assembly processes
- Reliable press-fit retention through precision-engineered base diameter (0.191") and 1" length for stable mounting
Professional Applications & Engineering Value
These 4-40 UNC steel press-fit studs deliver exceptional engineering value in electronics enclosures, machinery panels, and automotive assemblies where vibration resistance and permanent mounting are critical. The zinc-plated steel construction prevents galvanic corrosion while the fully threaded design ensures maximum load distribution across the entire engagement length. With Class 2A thread fit and UNC coarse threading, these studs eliminate cross-threading risks during installation while maintaining consistent clamping force. The precise 0.111" drill bit diameter compatibility and tight hole size tolerance (0.000" to 0.003") enable seamless integration into high-volume production lines, reducing installation time and improving manufacturing throughput.
Specification Summary & Compliance
Manufactured to precision standards with Class 2A thread fit and UNC coarse thread spacing. Features include 0.191" base diameter, 1" length, 59/64" thread length, and right-hand thread direction. Compliant with RoHS 3 (2015/863/EU) environmental regulations. Designed for 0.111" hole diameter with 0.04" minimum material thickness requirements. PEM® part number FH-440-16 ensures consistent quality and manufacturing traceability.
