Professional Applications & Engineering Value
These 3-48 UNC thread shoulder screws are engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making these screws suitable for applications in machinery, electronics, and automotive sectors where environmental factors are a concern. The hex socket drive allows for high torque application in confined spaces, while the knurled head enhances handling during installation. The Class 3A thread fit ensures tight tolerances and secure fastening, reducing the risk of loosening under vibration. This combination of features makes them ideal for use in pivots, rotating shafts, and guiding mechanisms, where the shoulder acts as a precise datum for components, improving overall assembly accuracy and longevity.
Specification Summary & Compliance
This shoulder screw features a 3-48 UNC coarse thread with a Class 3A fit for high precision, a shoulder diameter of 1/8" with tight tolerances, and a Rockwell B55 hardness. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety standards for industrial use.
