Professional Applications & Engineering Value
This 10-32 UNF Class 3A zinc-plated alloy steel rounded head screw delivers critical performance advantages for precision assembly applications. The fine UNF threading provides superior resistance to vibration loosening in machinery, electronics, and automotive components where reliability is paramount. The flanged construction distributes clamping force evenly, preventing surface damage while the button head profile offers a low-profile finish ideal for tight spaces. With fully threaded design and right-hand threading, installation efficiency is maximized in production environments. The combination of 120,000 psi tensile strength and Rockwell C32 hardness ensures these screws maintain integrity under dynamic loads, making them suitable for critical joints in industrial equipment, precision instruments, and heavy-duty assemblies.
Specification Summary & Compliance
This precision fastener features Class 3A thread fit for tight tolerance applications with 10-32 UNF fine threading and right-hand direction. Manufacturing specifications include 1/4" length, 0.406" flange diameter, and 1/8" hex drive. The screw is fully threaded for maximum engagement and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards for environmental safety and regulatory acceptance in global markets.
