S-92137A250 M3 x 8 mm ISO 7380-2 Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional durability with Class 10.9 tensile strength (100,000 psi) and Rockwell C32 hardness for reliable performance in demanding applications
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh industrial environments
• Secure and efficient installation with the 2 mm hex drive and wide button head design, preventing cam-out and providing stable torque transfer
• Full thread engagement along the 8 mm length ensures maximum holding power and vibration resistance in assembled components
• Precision threading with Class 6g fit and M3 x 0.5 mm coarse pitch for quick assembly and consistent performance in metric systems
• Integrated flange design distributes clamping force evenly, reducing the need for separate washers and simplifying inventory
• Compliance with international standards including ISO 7380-2, RoHS 3, and REACH for global quality assurance and environmental safety

Professional Applications & Engineering Value

This M3 metric screw with Class 10.9 strength and black-oxide alloy steel construction addresses critical engineering challenges in industrial settings. The fully threaded design and coarse pitch (0.5 mm) enable rapid assembly and high vibration resistance, ideal for machinery, automotive, and electronic enclosures. The wide button head with 2 mm hex drive offers superior torque transmission, minimizing strip-out risks during high-stress fastening. Combined with the flange feature, it provides stable load distribution, preventing surface damage and ensuring long-term joint integrity. These attributes make it a reliable choice for heavy-duty applications requiring consistent performance under mechanical stress and exposure to corrosive elements.

Specification Summary & Compliance

This screw adheres to precise dimensional tolerances, including Class 6g thread fit per metric standards and ISO 7380-2 specifications for rounded head hex screws. It is manufactured from alloy steel with a black-oxide surface treatment and meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and suitability for global industrial supply chains.
