Professional Applications & Engineering Value

These 4-40 UNC steel press-fit studs solve critical challenges in precision assembly applications where traditional fastening methods prove inadequate. The zinc-plated steel construction provides essential corrosion protection for electronics enclosures, automotive components, and industrial control panels exposed to harsh environments. With fully threaded design and Class 2A thread fit, these studs maintain consistent clamping force while resisting vibration-induced loosening. The precise 0.111" hole diameter specification and controlled interference fit eliminate the need for secondary retention methods, significantly reducing installation time in high-volume manufacturing. Engineering teams benefit from the UNC coarse thread pattern's rapid assembly characteristics and the press-fit installation's elimination of tapping operations, making them ideal for automated production lines where reliability and speed are paramount.

Specification Summary & Compliance

Manufactured to exacting standards, these press-fit studs feature Class 2A thread fit per Unified National Coarse (UNC) specifications with 4-40 thread size. The components maintain precise dimensional control with 0.000" to 0.003" hole size tolerance for consistent press-fit performance. Full compliance with RoHS 3 (2015/863/EU) environmental directives ensures suitability for global markets, while the zinc-plated steel material provides reliable mechanical properties for industrial applications requiring durable threaded connections.
