This directory lists 67 fastener manufacturers across the United States, from high-volume standard product specialists to highly specialized custom cold heading houses and precision screw machining facilities.
Buyers engage these manufacturers to solve a range of critical engineering and production problems, from ensuring specific clamp loads and fatigue life requirements in structural assemblies to preventing issues like hydrogen embrittlement in high-strength, plated fasteners. The goal is to achieve reliable torque-tension relationships and dimensional stability across millions of cycles, whether for a commercial product or an aerospace component requiring full Production Part Approval Process (PPAP) documentation.
The types of fastener suppliers vary significantly: some focus on commodity parts like standard hex bolts and nuts, leveraging large-scale cold forming. Others specialize in custom-engineered components, employing processes like thread rolling for enhanced strength or producing unique designs via multi-station cold formers. Additionally, there are those who excel in niche markets, meeting exacting standards like IATF 16949 for automotive or AS9100 for aerospace, often providing value-added services like inventory management and engineering support.
