S-92832A326 M4 x 8 mm ISO 7380 Steel Button Head Torx Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for prolonged service life in demanding environments.
• Superior torque transmission and reduced cam-out thanks to the T20 Torx drive, ensuring secure fastening and efficient assembly.
• High mechanical strength and reliability with a Class 8.8 grade, 110,000 psi tensile strength, and Rockwell C22 hardness for heavy-duty applications.
• Excellent thread engagement and holding power provided by the fully threaded M4 x 0.7 mm coarse thread design with Class 6h fit.
• Streamlined, low-profile button head design that minimizes protrusion and provides a finished appearance while allowing for use in confined spaces.
• Guaranteed dimensional consistency and interchangeability through compliance with the precise ISO 7380 standard for rounded head screws.
• Safe for use in regulated industries as it meets RoHS 3 and REACH environmental compliance standards.

Professional Applications & Engineering Value

This M4 Torx button head screw is engineered to address critical challenges in industrial assembly, such as the need for high clamp load and vibration resistance. The zinc-plated steel material provides a protective barrier against oxidation, extending the fastener's lifespan in humid or outdoor settings. Its T20 Torx drive allows for higher torque application compared to traditional drives, reducing the risk of tool slippage and head stripping during installation. The fully threaded metric coarse thread (M4 x 0.7 mm) ensures maximum thread contact along the entire 8 mm length, enhancing pull-out strength in materials like metal and hard plastics. Ideal for machinery, automotive sub-assemblies, and electronic enclosures, this screw delivers reliable performance where high-strength fasteners with precise Class 6h thread fit are required to maintain structural integrity under dynamic loads.

Specification Summary & Compliance
