Professional Applications & Engineering Value
This 18-8 Stainless Steel Shoulder Screw is engineered to address common challenges in precision mechanical assemblies, such as misalignment and component wear. Its Class 3A thread fit and standard shoulder ensure exact positioning in applications like rotating shafts, pivots, and guides, reducing vibration and improving operational accuracy. The UNC coarse threads and knurled head facilitate quick installation in tight spaces, while the high tensile and shear strengths support demanding loads in industrial machinery, automotive systems, and electronic enclosures. Made from corrosion-resistant 18-8 stainless steel, it excels in environments exposed to moisture or chemicals, offering long-term reliability and reducing maintenance costs for B2B buyers seeking durable mechanical fasteners.
Specification Summary & Compliance
This shoulder screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and UNC coarse threading. The shoulder diameter and length feature minimal tolerances (e.g., -0.004" to -0.002" for diameter) to ensure consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility. Manufactured to high-quality benchmarks, it meets common industrial specifications for strength and durability.
