Professional Applications & Engineering Value
This 3-48 UNC coarse thread shoulder screw is engineered to address critical assembly challenges in precision machinery, automation systems, and electronic enclosures. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, making it suitable for humid or corrosive environments. Its hex socket head with a knurled texture ensures tool engagement remains firm, reducing cam-out and stripping risks during high-torque applications. The Class 3A thread fit and precise shoulder dimensions offer consistent alignment and load distribution, minimizing wear on mating parts. Ideal for use in industrial shoulder screws applications where reliability, dimensional accuracy, and compliance with RoHS and REACH are paramount for maintaining product integrity and operational efficiency.
Specification Summary & Compliance
This shoulder screw adheres to UNC coarse thread standards with a Class 3A thread fit for high precision. Dimensions include a thread diameter of 0.099", thread length of 5/32", and shoulder diameter of 1/8" with tight tolerances (e.g., shoulder diameter tolerance: -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 global industrial use.
