• High mechanical strength for critical applications, offering a tensile strength of 130,000 psi and a Rockwell C24 hardness.
• Flush and secure fastening facilitated by the standard 82° countersink angle and flat head design.
• Full-length threading for maximum grip and holding power across the entire 3/4" length of the screw.
• Compliance with major environmental regulations, being RoHS 3 and REACH compliant for global supply chain suitability.

Professional Applications & Engineering Value

Engineered for reliability, these 10-32 UNF Class 3A flat head screws are crafted from A286 Stainless Steel, a material chosen for its excellent strength at elevated temperatures and superior corrosion resistance compared to standard stainless grades. This makes them an ideal high-strength fastener for industrial applications in aerospace, automotive, and heavy machinery, where failure is not an option. The Torx T25 drive provides a significant engineering advantage, allowing for higher torque application without damaging the drive recess, which is critical during assembly and maintenance. The fine UNF thread and precise Class 3A thread fit ensure a tight, secure connection that resists loosening under vibration, solving common challenges in dynamic and high-stress environments. The 82° countersink angle allows the flat head to sit flush with the material surface, providing a clean finish and improved aerodynamics or material flow.
