- Broad industrial applicability due to right-hand threading and standardized 4-40 UNC thread size
Professional Applications & Engineering Value
These 4-40 UNC steel press-fit studs solve critical challenges in sheet metal assembly by eliminating tapping operations and reducing installation complexity. The zinc-plated steel construction provides durable corrosion protection for electronics enclosures, machinery panels, and automotive components exposed to humid conditions. With full coarse threading and Class 2A thread fit, they maintain vibration resistance while accommodating thermal expansion in industrial fastening applications. The precision 0.111" hole diameter requirement ensures flush mounting without secondary machining, streamlining high-volume production lines where press-fit hardware reliability is paramount.
Specification Summary & Compliance
Manufactured to UNC coarse thread standards with Class 2A external thread fit for consistent mating with nuts and threaded components. The studs feature 13/32" thread length on a 1/2" overall length, supporting 0.04" minimum material thickness with 7/32" minimum edge distance. Fully compliant with RoHS 3 (2015/863/EU) environmental directives, ensuring safe use in regulated industries. PEM® part number FH-440-8 guarantees adherence to established press-fit stud manufacturing specifications.
