S-95735A114 M12 x 20 mm JIS B 1189 Type 2 JIS High-Strength Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Corrosion-resistant zinc-plated steel construction provides enhanced durability and longevity, minimizing maintenance needs in harsh industrial environments.
• Flanged head design eliminates the need for separate washers, simplifying installation and providing a larger bearing surface for improved load distribution.
• Class 10.9 strength grade guarantees high mechanical properties, making it suitable for critical assemblies requiring superior bolt integrity.
• Extra fine 1.25mm pitch thread offers superior vibration resistance and precise clamping force, ideal for applications where loosening is a concern.
• Fully threaded shank allows for maximum grip length and adjustability, ensuring secure fastening across varying material thicknesses.
• External hex drive enables easy installation and removal with standard tools, reducing assembly time and labor costs.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M12 hex head flange screw addresses common challenges such as vibration-induced loosening and corrosion in machinery, automotive, and structural assemblies. The zinc-plated steel material provides a protective barrier against environmental factors, while the Class 10.9 strength rating and Rockwell C32 hardness ensure it withstands high tensile and shear loads without deformation. The flanged design integrates a washer-like base, distributing clamp load effectively and preventing surface damage, which is critical in repetitive disassembly scenarios. With its extra fine metric thread and fully threaded body, it delivers consistent preload and enhanced grip in precision equipment, reducing downtime and maintenance costs for B2B clients.
