Professional Applications & Engineering Value
These 18-8 stainless steel shoulder screws with 3-48 UNC coarse threading are engineered to address critical alignment and pivot point requirements in machinery, automation, and precision equipment. The Class 3A thread fit minimizes backlash and ensures consistent clamping force, reducing maintenance needs in high-vibration settings. The knurled socket head enhances grip during installation, preventing cam-out and damage to the drive. With a Rockwell B55 hardness and robust 70,000 psi tensile strength, they withstand repetitive loads and corrosive conditions, making them ideal for use in robotics, conveyor systems, and electronic enclosures where reliability and dimensional accuracy are paramount.
Specification Summary & Compliance
This product adheres to UNC thread standards with a Class 3A thread fit for precise engagement. Shoulder diameter and length tolerances are tightly controlled (e.g., shoulder diameter tolerance: -0.004" to -0.002") to ensure consistent performance. Manufacturing and material compliance include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental and safety standards are met for industrial use.
