S-95440A120 M6 x 30 mm ASTM A276 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life.
• Enhanced durability and strength from a 70,000 psi tensile strength and Rockwell B70 hardness, reducing the risk of fastener failure.
• Secure and flush installation thanks to the 100° countersink angle and undercut flat head profile for a clean, professional finish.
• Efficient installation and removal with a 4 mm hex drive, providing a positive grip and minimizing tool slippage.
• Reliable thread engagement with a Class 6g thread fit and coarse M6 x 1 mm thread, ensuring consistent performance in various materials.
• Long-term environmental compliance by meeting RoHS 3 and REACH standards, making them safe for regulated industries.
• Full-length threading for maximum grip and holding power across the entire 30 mm length of the screw.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M6 flat head screws address critical challenges like corrosion and mechanical stress. The 316 Stainless Steel material offers exceptional resistance to chemicals and moisture, preventing degradation in marine, chemical processing, and outdoor applications. The black oxide finish not only adds a layer of corrosion protection but also reduces light reflection, which is beneficial in sensitive optical or assembly environments. Combined with the hex drive and fully threaded design, these screws provide high clamp load and ease of installation in tight spaces, making them a reliable choice for machinery, structural frameworks, and electronic enclosures where vibration resistance and long-term integrity are paramount.

Specification Summary & Compliance

This metric screw features precise dimensions including an M6 x 1 mm coarse thread with a Class 6g thread fit for standard tolerance applications. The head diameter tolerance is maintained between -0.127 to 0.127 mm for consistent seating. Manufacturing and material specifications conform to ASTM A276, ensuring high-quality stainless steel. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances for safe use in global markets.
