S-90327A202 M12 x 50 mm DIN 7984 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated alloy steel construction, extending service life in harsh industrial environments
• High tensile strength of 110,000 psi and Class 8.8 rating for reliable performance in demanding mechanical applications
• Precision Class 6g thread fit ensures smooth assembly and secure fastening with minimal risk of cross-threading
• Low-profile socket head design with 8mm hex drive allows for easy installation in confined spaces with standard tools
• Partially threaded configuration provides optimal grip and clamping force distribution for structural integrity
• Rockwell C20 hardness maintains thread integrity and prevents deformation under high stress conditions
• Compliance with DIN 7984 standards guarantees dimensional accuracy and interchangeability in metric fastener systems

Professional Applications & Engineering Value

Engineered for precision machinery and heavy-duty equipment, these M12 socket head cap screws address critical challenges in industrial assembly. The zinc-plated alloy steel construction provides essential corrosion protection for components exposed to moisture or chemicals, while the Class 8.8 strength rating ensures reliable performance under vibration and dynamic loads. The low-profile socket head design enables flush mounting in tight spaces where standard hex bolts cannot be used, making them ideal for machine frames, automotive components, and production equipment. With coarse 1.75mm pitch threads and partial threading, these fasteners deliver faster installation and superior resistance to loosening compared to fine-thread alternatives.

Specification Summary & Compliance

This metric socket head cap screw features M12×1.75mm coarse threads with Class 6g thread fit tolerance per ISO standards, ensuring precise engagement in metric applications. The 50mm length provides 30mm of threaded engagement for secure fastening. Manufacturing complies with DIN 7984 specifications for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making these fasteners suitable for global industrial supply chains.
