S-92981A915 M10 ASTM A108 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional strength and durability with 140,000 psi tensile strength and Rockwell C32 hardness, ideal for heavy-duty industrial applications.
• Superior corrosion resistance provided by the black oxide finish, extending the screw's service life in demanding environments.
• Precise alignment and smooth rotation thanks to the 12mm shoulder diameter, ensuring accurate component positioning.
• Reliable and secure fastening with a Class 5g6g thread fit, minimizing the risk of loosening under vibration and load.
• Easy installation and removal using a standard 6mm hex key drive and a knurled head for enhanced grip.
• Broad industry compliance meeting ASTM A108 material specifications, RoHS 3, and REACH environmental standards.
• Optimized for metric assemblies with M10x1.5 coarse threads and a 16mm thread length for efficient engagement in various materials.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered from alloy steel to address critical challenges in precision machinery and automation systems. The black oxide finish not only enhances corrosion resistance but also reduces galling during installation, a common issue in high-cycle applications. The integral 12mm shoulder provides a precise pivot or bearing surface, eliminating the need for additional bushings and reducing assembly complexity in industrial equipment, jigs, and rotating mechanisms. With its hex drive and knurled head, it ensures secure tool engagement and manual adjustment, making it ideal for maintenance-heavy environments. The Class 5g6g thread fit guarantees consistent clamping force, preventing joint failure in heavy-duty applications subjected to dynamic loads and vibrations.

Specification Summary & Compliance

This metric shoulder screw features precise dimensional tolerances, including a shoulder diameter tolerance of -0.072 to -0.01 mm and a shoulder length tolerance of 0 to 0.25 mm. The M10x1.5 coarse thread conforms to standard metric thread specifications with a Class 5g6g fit for reliable performance. Manufactured in compliance with ASTM A108 for material consistency, it is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations.
