Professional Applications & Engineering Value

This 4-40 UNC press-fit stud delivers exceptional engineering value in steel applications where vibration resistance and permanent retention are critical. The zinc-plated steel construction provides reliable corrosion protection while the fully threaded design ensures maximum engagement throughout the installation depth. Engineered specifically for 0.111" holes in materials as thin as 0.04", this press-fit stud eliminates the need for welding or adhesives in sheet metal assemblies. The Class 2A thread fit guarantees compatibility with standard UNC coarse thread components, while the right-hand threading facilitates conventional assembly processes. Ideal for electronics enclosures, machinery panels, and automotive components where reliable, permanent threaded connections are essential.

Specification Summary & Compliance

This steel press-fit stud features precision 4-40 UNC coarse threading with Class 2A thread fit tolerance for consistent mating performance. The manufacturing specifications include a base diameter of 0.191", thread length of 43/64", and total length of 3/4". Installation requires a No. 34 drill bit for 0.111" holes with hole size tolerance of 0.000" to 0.003". The product maintains RoHS 3 (2015/863/EU) compliance and follows PEM® engineering standards for press-fit fastener applications, ensuring reliable performance in industrial environments.
