S-90358A151 M12 x 20 mm Alloy Steel Ultra-Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 PSI ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life and maintaining integrity in harsh industrial environments.
• Precision thread fit (Class 5g6g) guarantees consistent engagement and secure fastening, minimizing assembly issues and improving joint reliability.
• Ultra-low socket head profile allows for installation in tight spaces, offering design flexibility and ease of use with a standard 6mm hex drive.
• High hardness (Rockwell C32) provides excellent wear resistance, ensuring the screw maintains its form and function through repeated use.
• Full threading and coarse pitch enable quick installation and strong holding power, ideal for applications requiring rapid assembly and disassembly.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global standards for hazardous substance restrictions.

Professional Applications & Engineering Value

This M12 socket head cap screw is engineered to address common industrial challenges, such as vibration loosening and space constraints. Made from black-oxide alloy steel, it offers enhanced durability and corrosion protection, making it suitable for machinery, automotive, and heavy equipment applications. The ultra-low head profile and coarse thread pitch facilitate easy access and fast installation in confined areas, while the Class 5g6g thread fit ensures precise alignment and reduces the risk of cross-threading. With a high tensile strength and full threading, it provides reliable clamping force in dynamic environments, minimizing maintenance needs and downtime for B2B users.
