S-94331A116 M5 x 20 mm Stainless Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional high-temperature performance with A286 stainless steel construction, maintaining structural integrity under demanding thermal conditions
• Superior torque transmission and strip resistance through the Torx T25 drive system, reducing tool slippage and installation damage
• Precision thread engagement with Class 6g metric tolerance ensuring reliable fastening in coarse thread applications
• High tensile strength rating of 130,000 psi provides critical load-bearing capacity for heavy-duty industrial assemblies
• Optimized countersinking capability with 90° flat head profile for flush mounting in precision-machined components
• Enhanced durability from Rockwell C24 hardness, resisting wear and deformation through repeated use cycles
• Full threading along 20mm length enables maximum grip range and adjustment flexibility in varied material thicknesses

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M5 flat head screws leverage A286 stainless steel's exceptional creep resistance and strength retention at elevated temperatures up to 700°C. The Torx T25 drive system addresses common installation challenges by distributing torque evenly across six contact points, preventing cam-out incidents that compromise fastener integrity. With Class 6g thread precision and coarse thread pitch, these fully threaded screws ensure rapid assembly while maintaining vibration resistance in machinery, automotive subsystems, and aerospace components. The 90° countersink angle integrates seamlessly with standard chamfered holes, creating clean, flush surfaces critical for aerodynamic and safety-critical applications.

Specification Summary & Compliance

Manufactured to metric thread standards with Class 6g tolerance for consistent fit across mating components. The M5x0.8mm coarse thread configuration adheres to ISO metric specifications while the 20mm length provides standardized dimensional consistency. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for global industrial applications. Mechanical properties include 130,000 psi tensile strength and Rockwell C24 hardness verified through quality control processes.
