S-98075A143 1/4"-20 Rivet Studs

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Maximum holding power achieved through fully threaded design that distributes load evenly across the entire stud length
• Easy installation and compatibility with standard 25/64" drill bits and Class 2A thread fit for quick assembly operations
• Versatile material thickness accommodation ranging from 0.027" to 0.165" for diverse application requirements
• Reliable coarse UNC threading (1/4"-20) providing excellent resistance to vibration loosening in heavy-duty applications
• Enhanced stability from the 0.5" flange diameter that creates a wider bearing surface for improved load distribution
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This zinc-plated steel rivet stud delivers exceptional engineering value through its fully threaded UNC design that addresses common industrial fastening challenges. The coarse 1/4"-20 threading provides superior resistance to vibration-induced loosening, making it ideal for machinery, equipment frames, and structural assemblies where maintaining clamp load is critical. The zinc plating offers reliable corrosion protection in manufacturing environments, while the 0.5" flange diameter distributes stress over a wider area, preventing material deformation in sheet metal applications. Engineered for material thicknesses from 0.027" to 0.165", this industrial rivet stud ensures consistent performance across various assembly scenarios, from automotive components to industrial enclosure manufacturing.

Specification Summary & Compliance

This heavy-duty fastener features precision Class 2A thread fit per UNC standards with right-hand coarse threading (1/4"-20) and a body diameter of 0.39". Manufactured to exacting dimensional tolerances, it requires a 25/64" drill bit for proper installation. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The fully threaded design provides consistent engagement throughout the 5/8" thread length for reliable performance in demanding applications.
