S-90128A299 M12 x 50 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capability with Class 12.9 strength rating and 170,000 psi tensile strength for reliable performance in high-stress environments
• Superior corrosion resistance provided by zinc plating on alloy steel, extending service life in demanding industrial conditions
• Precise torque transmission through 10mm hex drive socket design, preventing tool slippage and ensuring secure fastening
• Optimized thread engagement with Class 5g6g thread fit and M12 x 1.75mm coarse thread profile for quick installation and vibration resistance
• Versatile partial threading (36mm thread length on 50mm screw) allowing both clamping and alignment functions in assembly applications
• Consistent dimensional accuracy meeting DIN 912/ISO 4762 standards for reliable interchangeability and fit
• Enhanced durability with Rockwell C37 hardness maintaining structural integrity under repeated loading cycles

Professional Applications & Engineering Value

These M12 socket head cap screws deliver critical engineering solutions where standard fasteners fail. The zinc-plated alloy steel construction provides essential corrosion protection for automotive assemblies, heavy machinery, and industrial equipment exposed to harsh environments. The Class 12.9 strength rating ensures dependable performance in high-vibration applications, preventing joint failure in critical connections. The partially threaded design offers dual functionality - the unthreaded section acts as a precision pilot for alignment, while the coarse metric thread enables rapid assembly in production environments. The hex drive socket accommodates high torque applications where space constraints prevent conventional wrench access, making these socket head cap screws ideal for compact machinery designs and maintenance applications requiring reliable disassembly and reassembly.

Specification Summary & Compliance
