Professional Applications & Engineering Value
This Grade 2 Titanium shoulder screw is engineered to address critical challenges in precision machinery, aerospace, and medical devices where high strength-to-weight ratio and corrosion resistance are paramount. The 10-24 UNC coarse thread with Class 3A fit provides excellent engagement in metals and plastics, reducing the risk of stripping. The precisely machined 1/4" shoulder diameter and 1" shoulder length act as a reliable pivot or spacer, maintaining alignment in rotating assemblies and reducing wear. With a socket head and knurled texture, it ensures secure handling in tight spaces, making it ideal for applications demanding repeatable accuracy and long-term reliability under dynamic loads.
Specification Summary & Compliance
This shoulder screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for precise engagement. Key dimensions include a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and shoulder length of 1" (tolerance: -0.005" to 0.005"). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it meets stringent environmental and safety standards for industrial use.
