S-94331A107 M4 x 8 mm Stainless Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion and heat resistance from A286 stainless steel, ensuring long-term reliability in harsh industrial environments.
• Superior torque transmission and strip-out resistance with the T20 Torx drive, allowing for higher tightening forces and secure installations.
• Precise and reliable thread engagement due to the Class 6g thread fit, minimizing the risk of cross-threading and ensuring consistent performance.
• High mechanical strength with a 130,000 psi tensile strength and Rockwell C24 hardness, providing excellent load-bearing capacity for demanding applications.
• Optimal flush mounting with a standard 90° countersink angle and flat head profile, creating a smooth, aerodynamic surface finish.
• Full thread engagement along the 8mm length for maximum grip and holding power in a compact form factor.
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

This M4 x 0.7mm A286 Stainless Steel Flat Head Screw is engineered to solve critical fastening challenges in high-stress, high-temperature environments. The A286 material offers excellent resistance to oxidation and creep, making these metric screws ideal for aerospace, automotive, and heavy machinery applications where failure is not an option. The Torx T20 drive system provides a significant advantage over traditional drives, enabling higher torque application without cam-out, which is crucial for assemblies requiring precise clamp load. Combined with the Class 6g thread precision and coarse thread pitch, these screws ensure rapid installation and vibration resistance, reducing maintenance downtime and improving the overall integrity of your mechanical designs.
