Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw with a 10-32 UNF fine thread is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The precise shoulder fit (1/4" diameter with tight tolerances) ensures accurate component positioning in assemblies like rotating shafts, linkages, and bearing supports, reducing friction and extending service life. Its low-profile socket head and right-hand thread facilitate quick installation in compact machinery, while the fine thread spacing enhances grip in high-vibration settings. Made from durable stainless steel, it resists rust and chemicals, making it suitable for automotive, aerospace, and electronics applications where reliability and regulatory compliance are critical.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit per UNF standards, ensuring precise dimensional accuracy. The shoulder diameter is 1/4" with a tolerance of -0.001" to 0", and the shoulder length is 1/8" with a tolerance of 0" to 0.002" for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
