Professional Applications & Engineering Value
This 10-32 UNF shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, extending service life in demanding conditions like assembly jigs, rotating shafts, and precision machinery. The 1" shoulder length with precise tolerances ensures accurate positioning of components, reducing wear and misalignment. Combined with a low socket head profile and slotted drive, it facilitates easy installation in confined spaces while maintaining a secure hold. The UNF fine thread enhances grip in materials prone to vibration, making it a reliable choice for automotive, aerospace, and electronic equipment where precision shoulder screws are essential for operational efficiency.
Specification Summary & Compliance
This shoulder screw adheres to Class 2A thread fit for consistent engagement and meets standard UNF threading specifications. The shoulder features a diameter of 1/4" with a tolerance of -0.001" to 0" and a length of 1" with a tolerance of 0" to 0.002" for precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
