Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw with a Black Oxide finish is engineered to address critical challenges in precision assembly and machinery. The Class 3A thread fit and standardized shoulder diameter provide exact positioning, reducing misalignment in pivots, gears, and linkages. Its coarse 5-40 UNC thread ensures rapid installation and robust clamping force, while the knurled socket head with a hex drive prevents tool slippage during high-torque fastening. Ideal for industrial applications such as automotive components, electronic enclosures, and conveyor systems, this screw offers exceptional corrosion resistance and mechanical strength, minimizing downtime and maintenance costs in demanding operational environments.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a precise Class 3A fit for tight tolerances. The shoulder diameter and length maintain standard fits with specified tolerances (e.g., shoulder diameter: -0.004" to -0.002"). 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 various industrial and export requirements.
