S-90729A624 M10 x 50 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 environments and extended service life.
• High-strength fastening performance offering a tensile strength of 70,000 psi and Rockwell B70 hardness for reliable load-bearing applications.
• Efficient installation and removal with a 6mm hex drive, providing a secure grip and reducing the risk of tool slippage.
• Optimal flush seating due to the 100° countersink angle and undercut flat head profile, ensuring a clean, professional finish.
• Precise and reliable thread engagement with a Class 6g thread fit and coarse M10x1.5mm thread, enabling quick assembly and vibration resistance.
• Full-threaded design for maximum grip length and holding power along the entire 50mm shank.
• Compliance with industry standards including ASTM A276, RoHS 3, and REACH, ensuring material quality and environmental safety for global supply chains.

Professional Applications & Engineering Value

This M10 flat head screw is engineered to address critical challenges in industrial and marine settings where corrosion resistance and structural integrity are paramount. The use of 316 Stainless Steel with a passivated finish provides exceptional protection against chlorides and acidic conditions, preventing fastener failure in demanding applications like chemical processing equipment, offshore platforms, and food machinery. The fully threaded metric coarse thread (M10x1.5mm) ensures rapid installation and high clamp load distribution, while the hex drive and undercut flat head design allow for countersunk, low-profile fastening that resists loosening under vibration. These features make it a reliable choice for securing components in assemblies requiring flush surfaces and long-term durability without maintenance.

Specification Summary & Compliance

This screw features a metric M10 x 1.5mm coarse thread with a Class 6g tolerance for precise fit. Dimensions include a head diameter of 20 mm (tolerance: -0.127 to 0.127 mm), head height of 3.5 mm, and length of 50 mm. It is manufactured in compliance with ASTM A276 for material specification and is verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to restricted substance regulations for safe use in industrial and consumer products.
