Professional Applications & Engineering Value
This stainless steel shoulder screw is engineered to address common industrial challenges, such as component misalignment and wear in high-stress environments. The 18-8 stainless steel material combined with a black oxide finish provides excellent corrosion resistance, extending service life in applications like machinery, automotive systems, and precision instruments. The 10-32 UNF fine thread and Class 3A fit ensure tight, reliable connections that resist loosening under vibration, while the 1/4" shoulder diameter acts as a precise pivot or spacer, reducing assembly time and improving alignment in industrial shoulder screw uses. Its hex drive and knurled head facilitate quick installation, making it a versatile choice for engineers seeking durability and compliance in demanding settings.
Specification Summary & Compliance
This shoulder screw adheres to ASME B18.3 specifications, with precise dimensions including a 1/4" shoulder diameter and 1/4" thread length. Threads are manufactured to Class 3A fit under the UNF standard, ensuring high accuracy and reliability. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for industrial use without hazardous substances.
