Professional Applications & Engineering Value
This 3-48 UNC shoulder screw in 316 stainless steel is engineered to address critical challenges in precision machinery, such as alignment and load distribution. The hex socket head and knurled texture provide secure tool engagement, reducing slippage during installation in tight spaces. Its Class 3A thread fit and coarse thread design ensure consistent performance in high-vibration environments, like robotics and automotive assemblies, where loosening can lead to failure. The shoulder diameter and length tolerances allow for exact positioning, minimizing wear on moving parts. Ideal for industrial applications requiring corrosion resistance and strength, this screw supports long-term reliability and reduces maintenance needs.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise thread engagement. Dimensions include a thread size of 3-48, head diameter of 0.25", and drive size of 5/64". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufactured to maintain tight tolerances, such as shoulder diameter tolerance of -0.004" to -0.002", it supports consistent performance in regulated industrial settings.
