Professional Applications & Engineering Value

These 4-40 jack screws deliver critical performance where precision alignment and secure spacing are paramount. The zinc-plated 12L14 steel construction provides essential corrosion protection while maintaining the 55,000 psi tensile strength required for structural integrity in electronic enclosures, machinery guards, and precision instrumentation. The Class 2A thread fit ensures consistent engagement with mating components, eliminating play and maintaining positional accuracy in vibration-prone environments. With their male-female thread design, these screws serve as ideal standoffs and spacing elements in assembly applications where both mounting and receiving threads are necessary, streamlining inventory while providing reliable industrial fastening solutions.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit for external threads and Class 2B for internal threads, ensuring consistent mating performance. All critical dimensions including 3/16" hex size and overall length maintain tight ±0.005" tolerances for reliable installation. The product fully complies with RoHS 3 (2015/863/EU) regulations under exemption 6(a)-I for lead as an alloying element in steel, meeting international environmental standards for industrial components.
