S-90729A622 M10 x 35 mm ASTM A276 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction and passivated finish, ideal for harsh industrial environments
• High tensile strength of 70,000 psi ensures reliable fastening under demanding mechanical loads
• Precise Class 6g thread fit guarantees smooth installation and secure mating with nuts or tapped holes
• Undercut flat head design with 100° countersink angle provides a flush, low-profile finish and reduces risk of head protrusion
• 6mm hex drive allows for high-torque application with standard tools, minimizing slippage
• Full threading along the 35mm length offers maximum grip and adjustability in various material thicknesses
• Compliance with ASTM A276, RoHS 3, and REACH ensures material integrity and environmental safety for global supply chains

Professional Applications & Engineering Value

Engineered for industrial applications where corrosion resistance and mechanical reliability are critical, this M10 flat head screw in 316 Stainless Steel excels in chemical processing, marine, and outdoor equipment. The passivated finish enhances surface durability against chlorides and acids, while the coarse thread (1.5mm pitch) and fully threaded design ensure rapid assembly and strong holding power in soft or brittle materials. The undercut head profile and 100° countersink angle prevent surface damage and allow seamless integration into pre-drilled holes, reducing stress concentration. With a Rockwell B70 hardness and 70,000 psi tensile strength, it withstands vibration and dynamic loads, making it a trusted choice for machinery, structural frames, and precision assemblies requiring metric hex drive efficiency.

Specification Summary & Compliance

This flat head screw adheres to precise dimensional tolerances, including a head diameter tolerance of -0.127 to 0.127 mm and Class 6g thread fit per metric standards. Manufacturing and material specifications meet ASTM A276 for stainless steel bars and shapes, ensuring consistent quality. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances and supporting sustainable procurement practices in industrial sectors.
