S-97345A367 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Enhanced durability and load capacity from 70,000 psi tensile strength and 35,000 psi shear strength, ensuring reliable performance under stress.
• Precise assembly and secure fit with Class 3A thread fit and UNC coarse threads, reducing the risk of cross-threading and improving installation efficiency.
• Non-slip, easy manual adjustment thanks to the knurled head texture, providing better grip during handling without specialized tools.
• Space-saving and versatile mounting with a standard hex socket drive (3/32"), allowing access in confined spaces and compatibility with common tools.
• Stable alignment and reduced wear due to the precision shoulder diameter and length tolerances, maintaining component positioning in mechanical assemblies.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries and international markets.

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address common industrial challenges such as corrosion, misalignment, and mechanical failure. The UNC coarse threads with Class 3A fit provide quick, secure fastening in applications like machinery, automotive systems, and electronic enclosures, where vibration resistance is critical. The knurled head enhances grip for manual adjustments, while the hex socket drive ensures torque efficiency in tight spaces. Made from corrosion-resistant 316 stainless steel, it excels in humid or chemical-exposed environments, reducing maintenance costs and extending service life. Ideal for precision assemblies requiring high tensile strength and reliable shoulder support, this screw delivers consistent performance in demanding B2B settings.
