Professional Applications & Engineering Value
This 18-8 Stainless Steel Shoulder Screw is engineered to address critical alignment and pivot point challenges in precision machinery. The 5-40 UNC Class 3A thread provides a secure, high-tolerance fit that resists loosening under vibration, a common failure point in automated systems. The integral shoulder, with its tight diameter tolerance, acts as a precise locating dowel for gears, bearings, and linkages, eliminating the need for additional components and reducing assembly time. The combination of a knurled head and 5/64" hex drive ensures a firm grip during installation, even in confined spaces. Made from corrosion-resistant stainless steel, it delivers long-term reliability in demanding environments such as food processing, packaging, and medical equipment, where durability and compliance are non-negotiable.
Specification Summary & Compliance
This precision shoulder screw adheres to UNC (Unified Coarse) thread standards with a high-precision Class 3A thread fit for superior engagement. The shoulder diameter is manufactured to a tight tolerance of -0.004" to -0.002". The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for regulated markets and environmentally conscious supply chains.
