S-91239A246 M5 x 50 mm ISO 7380 Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel prolongs service life in harsh industrial environments, minimizing maintenance and replacement costs.
• High hardness rating of Rockwell C32 provides excellent wear resistance, maintaining thread integrity and drive engagement through repeated use.
• Precise Class 6g thread fit guarantees smooth installation and secure fastening, reducing assembly time and improving joint reliability.
• Fully threaded M5 coarse pitch design offers maximum grip length and faster installation compared to fine-thread alternatives.
• Standard hex drive compatibility with common 3mm tools enables quick and easy installation without specialized equipment.
• Comprehensive compliance with ISO 7380, RoHS 3, and REACH ensures international quality standards and environmental safety for global supply chains.

Professional Applications & Engineering Value

These M5 button head screws deliver critical engineering value through their black-oxide alloy steel construction and Class 10.9 strength rating. The combination of 140,000 psi tensile strength and Rockwell C32 hardness addresses common industrial challenges like vibration-induced loosening and material fatigue in machinery, automotive, and equipment assembly. The fully threaded metric coarse pitch design ensures maximum thread engagement in both soft and hard materials, while the rounded head profile provides a secure, low-profile finish that won't snag on components. With ISO 7380 compliance and hex drive convenience, these screws offer reliable performance in automated production environments where consistent torque application and corrosion resistance are essential.
