S-90358A019 M6 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 in high-stress applications, reducing the risk of fastener failure.
• Ultra-low socket head profile allows for installation in tight spaces and provides a sleek, low-clearance design for streamlined assemblies.
• Black-oxide finish on alloy steel offers enhanced corrosion resistance, extending the screw's service life in demanding industrial environments.
• Precision Class 5g6g thread fit guarantees consistent engagement and reliable clamping force, minimizing assembly issues and improving joint integrity.
• Rockwell C32 hardness provides excellent wear resistance and durability, maintaining thread integrity through repeated use and high torque applications.
• Full threading along the 20mm length offers versatile fastening options and uniform load distribution across the entire engaged length.
• Strict length tolerance of ±0.127mm ensures dimensional accuracy for precise fitment and consistent performance in automated or high-volume assembly.

Professional Applications & Engineering Value

These M6 socket head cap screws deliver critical engineering value in applications where space constraints and high mechanical demands coexist. The ultra-low profile head solves clearance issues in compact machinery, while the black-oxide alloy steel construction withstands harsh operational environments without sacrificing strength. The Class 5g6g thread fit and coarse 1mm pitch ensure quick assembly and reliable performance in vibration-prone equipment, making them ideal for industrial automation, precision machinery, and heavy-duty manufacturing. Their fully threaded design provides maximum adjustability and clamping force distribution, addressing common challenges of load concentration and joint loosening in dynamic applications.
