S-92235A111 M4 x 12 mm Flanged Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Class 12.9 rating and 170,000 psi tensile strength, ideal for high-stress industrial environments
• Superior corrosion resistance and durability thanks to the black-oxide finish on alloy steel, extending service life in harsh conditions
• Precise and secure fastening with a 3mm hex drive and standard socket head, ensuring easy installation and reduced tool slippage
• Versatile full-thread design provides consistent grip along the entire 12mm length, accommodating various material thicknesses
• Enhanced load distribution from the integrated flange, minimizing surface damage and improving joint stability
• Compliance with international environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated industries
• Accurate metric threading (M4x0.7mm) with Class 6g fit for reliable engagement and vibration resistance in dynamic applications

Professional Applications & Engineering Value

Engineered for demanding industrial and mechanical assemblies, this M4 socket head cap screw delivers critical performance where failure is not an option. The black-oxide alloy steel construction combats rust and wear, while the Class 12.9 strength ensures it withstands extreme tensile and dynamic loads without stripping or shearing. Its fully threaded, right-hand metric design with a coarse pitch enables quick installation and robust holding power in metals, plastics, and composites. The flanged head eliminates the need for separate washers, reducing assembly time and providing a larger bearing surface to prevent embedding. Ideal for machinery, automotive components, and precision equipment, this screw addresses common pain points like loosening under vibration and corrosion in humid or chemically aggressive environments, ensuring long-term operational integrity.

Specification Summary & Compliance

This screw adheres to metric threading standards with an M4x0.7mm coarse thread and Class 6g tolerance for precise fit. Dimensions include a 12mm length, 7mm head diameter, and 9mm flange diameter. Manufactured from high-grade alloy steel with a Rockwell C39 hardness, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial applications.
