- Easy and secure installation with a 3/8" hex drive and knurled head for improved grip during tightening.
- Durable thread engagement with UNC coarse threads and Class 2A fit, ensuring consistent fastening in high-vibration applications.
- Enhanced material hardness at Rockwell B55, providing excellent resistance to deformation and abrasion over time.
- Compliance with environmental standards including RoHS 3 and REACH, making it suitable for regulated industries.
Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw is engineered to address critical challenges in industrial applications where precision alignment and durability are paramount. The black oxide finish enhances corrosion resistance, extending service life in moist or chemically aggressive settings. With a high-strength 70,000 PSI tensile rating and 35,000 PSI shear strength, it reliably supports heavy loads in machinery, automation systems, and pivoting mechanisms. The 2 1/2" shoulder length with minimal tolerances ensures accurate positioning of components, reducing wear and maintenance costs. The coarse UNC threads and Class 2A fit facilitate quick assembly and secure fastening, even in high-vibration environments, while the hex drive and knurled head enable efficient installation with standard tools.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Dimensions include a 3/4"-10 thread size, 7/8" thread length, and shoulder diameter tolerance of -0.004" to -0.002". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances for safe industrial use.
