S-90324A034 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
• Enhanced assembly precision through Class 3A thread fit, ensuring reliable, vibration-resistant connections.
• High mechanical strength with 70,000 psi tensile and 35,000 psi shear ratings for demanding applications.
• Secure, non-slip fastening thanks to the knurled hex socket head design for improved tool grip.
• Left-hand thread functionality prevents loosening in rotating machinery where right-hand threads may fail.
• Durable performance backed by Rockwell B55 hardness, resisting wear and deformation.
• Environmental compliance with RoHS 3 and REACH standards, meeting global regulatory requirements.

Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw is engineered to address critical challenges in precision assemblies, such as in machinery, automation, and electronic enclosures. The left-hand UNC coarse thread and Class 3A fit provide exceptional resistance to unintentional loosening under counter-clockwise motion, while the 1/4" shoulder length ensures accurate component alignment and spacing. The knurled hex socket head enhances torque application, reducing slippage during installation. With high tensile and shear strength, it supports heavy-duty operations, making it a reliable choice for industrial applications requiring durability and compliance with RoHS and REACH standards.
