• Efficient hex drive installation with a 1/8" drive size for easy, high-torque application and reduced tool slippage.
• Optimal flush mounting with a standard 82° countersink angle and flat head design for a smooth, finished surface.
• Full threading along the 7/8" length provides maximum grip and uniform load distribution across the entire fastener.
• Broad industry compliance meeting ASME B18.3, ASTM F879, RoHS 3, and REACH standards for assured quality and safety.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these 10-24 UNC flat head screws in 316 Stainless Steel address common challenges like corrosion, vibration, and high tensile loads. The passivated finish enhances surface durability, resisting chemicals and moisture in marine, chemical processing, and outdoor applications. With a coarse thread spacing and fully threaded design, they ensure rapid assembly and superior holding power in materials prone to stripping. The hex drive and precise 82° countersink angle facilitate quick, flush installations, reducing assembly time and improving aesthetic finishes in machinery, enclosures, and structural frameworks where reliability is non-negotiable.

Specification Summary & Compliance

This screw adheres to strict dimensional tolerances, including a Class 3A thread fit per UNC standards for precision, a head diameter of 0.411" with specified tolerance, and a length of 7/8". It conforms to ASME B18.3 and ASTM F879 manufacturing specifications, ensuring consistent performance. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material restrictions are met for global supply chain integration.
