Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
- Precise component alignment ensured by the 3/8" shoulder diameter with tight tolerances, reducing wear and misalignment in assemblies.
- High-strength performance delivering 70,000 psi tensile and 35,000 psi shear strength for reliable load-bearing in demanding applications.
- Secure, non-slip fastening facilitated by the knurled socket head and hex drive, allowing for high-torque installation without stripping.
- Exceptional thread reliability with Class 3A fit and 10-32 UNF fine thread, providing vibration resistance and secure connections.
- Enhanced durability from Rockwell B55 hardness, maintaining integrity under repeated stress and mechanical forces.
- Regulatory peace of mind with compliance to ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards are met.
Professional Applications & Engineering Value
This stainless steel shoulder screw is engineered to address critical alignment and strength challenges in industrial applications. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for machinery, automotive, and electronics where exposure to moisture or chemicals is common. The 10-32 UNF fine thread and Class 3A thread fit ensure tight, vibration-resistant fastening, reducing the risk of loosening in dynamic systems. Combined with a knurled socket head for secure tool engagement, this screw provides reliable performance in precision assemblies, such as pivots, gears, and rotating shafts, where exact shoulder diameter and length tolerances prevent component shift and extend equipment lifespan.
Specification Summary & Compliance
This shoulder screw features a 10-32 UNF thread with Class 3A fit for high precision, a shoulder diameter of 1/4" with tolerance of -0.004" to -0.002", and shoulder length of 3/8" with tolerance of -0.005" to 0.005". It meets ASME B18.3 specifications for dimensional consistency and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances for safe use in various industries.
