S-90939A121 6-32 x 1" Stainless Steel Button Head Torx Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 130,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure.
• Superior corrosion resistance from A286 Stainless Steel material extends service life in harsh environments, minimizing maintenance needs.
• Enhanced torque transmission with T15 Torx drive reduces cam-out risk and allows for higher tightening forces without damaging the drive.
• Precise thread engagement with Class 2A UNC coarse threads provides consistent clamping force and faster installation in various materials.
• Low-profile rounded button head design offers a smooth finish and reduced snagging, ideal for applications where clearance is limited.
• Full threading along the 1" length ensures maximum grip and uniform stress distribution across the entire fastened joint.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets international standards for industrial use.

Professional Applications & Engineering Value

This A286 Stainless Steel Torx Button Head Screw is engineered to address critical challenges in high-stress environments, such as aerospace, automotive, and heavy machinery. The high tensile strength (130,000 psi) and Rockwell C24 hardness provide exceptional resistance to deformation and fatigue under dynamic loads. The fully threaded UNC coarse spacing ensures quick assembly and reliable hold in coarse-grained materials, while the T15 Torx drive enhances torque control, reducing installation errors and tool wear. Its rounded head profile minimizes protrusion, making it suitable for compact assemblies where safety and aesthetics are priorities. By combining robust material properties with precise Class 2A thread fit, this screw delivers consistent performance in applications demanding durability and compliance with industry standards like RoHS and REACH.
