- Reliable fastening performance with Class 2A thread fit and UNF fine thread design, reducing vibration loosening
- High strength under load with 70,000 psi tensile strength and Rockwell B55 hardness for demanding mechanical assemblies
- Easy installation and removal using standard 1/8" hex drive socket head, saving time in maintenance and assembly
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries
Professional Applications & Engineering Value
This precision shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision instruments. The 18-8 stainless steel base material combined with a TiCN coating provides exceptional resistance to corrosion and abrasion, making it suitable for environments exposed to moisture, chemicals, or repetitive motion. The 10-32 UNF fine thread and Class 2A fit ensure secure, vibration-resistant connections, while the precisely machined shoulder (1/4" diameter and length) allows for accurate component positioning in assemblies like rotating shafts, bearings, and linkages. This design minimizes misalignment and wear, reducing downtime and maintenance costs in industrial applications.
Specification Summary & Compliance
The screw features a Class 2A thread fit per UNF standards, with shoulder diameter tolerance of -0.002" to 0" and shoulder length tolerance of 0" to 0.003" for precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
