• Exceptional mechanical strength with 140,000 psi tensile strength and Rockwell C32 hardness for high-stress applications
• Precision length control with ±0.005" tolerance enabling consistent flush mounting and uniform clamping force
• Reliable hex drive performance using standard 3/32" tools for secure installation without cam-out
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

Engineered for precision machinery and compact assemblies, these 10-32 UNC socket head cap screws solve critical space constraints while maintaining structural integrity. The ultra-low profile head design enables installation in tight clearance applications where standard socket heads cannot fit, particularly valuable in electronic enclosures, precision instruments, and automated equipment. Manufactured from black-oxide alloy steel, these fasteners provide superior corrosion protection without dimensional compromise, while the Class 3A thread fit ensures minimal backlash and vibration resistance in dynamic applications. The combination of 140,000 psi tensile strength and fine thread spacing delivers reliable performance in high-vibration environments, making them ideal for aerospace components, medical devices, and precision manufacturing equipment where failure is not an option.

Specification Summary & Compliance

This 10-32 UNC socket head cap screw features precision Class 3A thread fit with right-hand orientation and fine thread spacing, manufactured to exacting dimensional standards including head diameter (0.312"), head height (0.063"), and length (5/16") with tight tolerance control (±0.005"). The fastener meets industry standards for inch system fasteners and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance compliance.
