Professional Applications & Engineering Value
These precision shoulder screws are engineered to address critical alignment and durability challenges in industrial applications. Made from 360 Brass, they offer excellent corrosion resistance and are non-magnetic, making them perfect for electronics, medical devices, and machinery where electrical properties matter. The 1/4" shoulder diameter and 3/8" shoulder length with precise tolerances ensure components are accurately positioned, reducing wear and misalignment. The 10-32 UNF fine thread and Class 2A fit provide a secure, vibration-resistant connection, essential for high-stress environments. With a socket head design and hex drive, installation is efficient, minimizing downtime in assembly lines and maintenance operations.
Specification Summary & Compliance
This shoulder screw adheres to Class 2A thread fit and UNF fine thread standards, ensuring dimensional accuracy and reliable performance. The shoulder diameter is precisely 1/4" with a tolerance of -0.002" to 0", and shoulder length is 3/8" with a tolerance of 0" to 0.003". It complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and REACH (EC 1907/2006), meeting environmental and safety regulations for industrial use.
