Professional Applications & Engineering Value

This zinc-plated steel press-fit stud delivers exceptional engineering value in sheet metal assemblies where vibration resistance and permanent fastening are critical. The fully threaded 1/4-20 UNC coarse thread design ensures maximum thread engagement, preventing loosening under dynamic loads while the press-fit installation creates a permanent, high-retention connection without requiring welding or adhesives. The zinc plating provides reliable corrosion protection for electronics enclosures, machinery panels, and automotive components exposed to moderate environmental conditions. With precise 0.249" hole diameter requirements and Class 2A thread fit, this stud maintains dimensional accuracy across production runs, reducing installation time and improving assembly consistency in high-volume manufacturing environments.

Specification Summary & Compliance

This press-fit stud features 1/4-20 UNC coarse threading with Class 2A thread fit per ASME standards, ensuring precise dimensional tolerances for reliable mating with standard components. The product maintains strict hole size tolerance of 0.000" to 0.003" for consistent press-fit performance. Manufactured from zinc-plated steel with full compliance to RoHS 3 (2015/863/EU) environmental standards, making it suitable for global industrial applications requiring restricted substance compliance. The stud is engineered for installation in materials with minimum 0.062" thickness and requires proper edge margin of 5/16" minimum from hole center to ensure optimal performance.
