• High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength for demanding applications
• Secure, non-slip installation provided by the knurled head and 5/64" hex drive for reliable torque transfer
• Wide compatibility with UNC coarse threading and right-hand direction for common industrial uses
• Enhanced durability from Rockwell B55 hardness, maintaining performance under repeated stress
• Environmental compliance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing

Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and strength challenges in precision assemblies. The Class 3A thread fit and standard shoulder work together to minimize misalignment in machinery, pivots, and rotating components, reducing wear and maintenance costs. Its UNC coarse thread and knurled socket head allow for quick, secure fastening in tight spaces, while the high tensile and shear strength ensures reliability in high-stress environments like automotive, aerospace, and industrial equipment. The corrosion-resistant material further extends service life, making it a cost-effective solution for mechanical fasteners requiring long-term performance.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise thread engagement. Dimensions include a 2-56 thread size, 5/64" hex drive, and shoulder diameter of 3/32" with tight tolerances (e.g., shoulder diameter tolerance of -0.004" to -0.002"). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence for global supply chains.
