Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and electronic enclosures. The 2-56 UNC coarse thread with Class 3A fit provides rapid assembly and vibration resistance, while the 7/8" shoulder length acts as a precise spacer or pivot, maintaining alignment in rotating assemblies. The knurled socket head with 5/64" hex drive allows for high-torque installation without stripping, and the material's inherent corrosion resistance ensures longevity in humid or chemical-exposed settings. Ideal for industrial applications requiring reliable, high-strength fastening with minimal maintenance.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Dimensions include a thread diameter of 0.086", shoulder diameter of 3/32" (tolerance: -0.004" to -0.002"), and shoulder length of 7/8" (tolerance: -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 regulated industries.
