Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life.
- Enhanced durability and wear resistance provided by the black oxide finish, which also reduces light reflection.
- High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength for reliable load-bearing in demanding applications.
- Precise and secure threading with Class 3A UNC coarse threads, ensuring excellent fit and vibration resistance.
- Easy installation and removal using the standard hex socket drive (3/32"), combined with a knurled head for improved grip.
- Accurate alignment and spacing due to the precisely machined shoulder with standard fit and tight tolerances.
- Compliance with major environmental regulations, including RoHS 3 and REACH, for safe and sustainable use.
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in industrial and mechanical assemblies, where corrosion resistance and high strength are paramount. The black oxide finish not only enhances durability but also minimizes galling and seizing in high-friction environments. Featuring UNC coarse threading and a Class 3A thread fit, it provides a secure, vibration-resistant connection that is essential for precision equipment, machinery linkages, and pivoting mechanisms. The knurled head and hex socket drive allow for efficient installation in tight spaces, reducing assembly time and improving operational reliability in applications such as automotive, aerospace, and heavy machinery.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Key dimensional tolerances include a shoulder diameter tolerance of -0.004" to -0.002" and a shoulder length tolerance of -0.005" to 0.005". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
