S-8077A217 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Enhanced durability and wear resistance from the black oxide finish, which also provides a sleek, non-reflective appearance.
• Exceptional mechanical strength with 70,000 psi tensile and 35,000 psi shear strength, ensuring reliable performance under high-stress conditions.
• Precise thread engagement and reliability due to the Class 3A thread fit and coarse UNC thread, reducing the risk of cross-threading and assembly errors.
• Secure, non-slip fastening enabled by the knurled socket head and hex drive, allowing for high torque application and easy installation.
• Accurate component alignment and spacing with the 2" precision shoulder, maintaining consistent positioning in assemblies.
• Compliance with strict environmental standards, including RoHS 3 and REACH, ensuring safety and regulatory adherence for global markets.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and heavy-duty equipment. The black oxide finish not only enhances corrosion resistance but also minimizes galling and seizing in high-friction applications. With a Class 3A thread fit and coarse UNC thread, it ensures quick, secure fastening in dynamic environments where vibration resistance is paramount. The 2" shoulder length provides a stable bearing surface for rotating parts, reducing wear and maintaining alignment in assemblies such as pivots, linkages, and guides. Its knurled socket head design offers superior grip for efficient installation, even in confined spaces, making it a reliable choice for industries like aerospace, automotive, and industrial manufacturing.
