Professional Applications & Engineering Value
These precision shoulder screws are engineered to solve critical alignment challenges in industrial machinery, automotive assemblies, and precision instruments. The 360 Brass construction offers excellent machinability and natural corrosion resistance, reducing downtime in humid or corrosive environments. With a Class 2A thread fit and fine 10-32 UNF threads, they provide secure, vibration-resistant fastening in applications requiring repeated adjustments. The 1/4" shoulder length and controlled diameter ensure exact component positioning, preventing misalignment in rotating parts or bearing mounts. This design is ideal for socket head configurations, allowing tight installations in confined spaces while maintaining high tensile strength and shear resistance for long-term reliability.
Specification Summary & Compliance
This product adheres to Class 2A thread fit standards for UNF fine threads, ensuring precise tolerances and interchangeability. The shoulder diameter is maintained within -0.002" to 0" tolerance, and shoulder length within 0" to 0.003" for consistent performance. It complies with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, confirming environmental safety and material integrity for global industrial use.
