Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw delivers exceptional engineering value in precision assembly applications where alignment and corrosion resistance are critical. The 1/4"-20 UNC coarse threads provide excellent vibration resistance in machinery, automotive, and industrial equipment, while the 1 1/4" shoulder length with tight diameter tolerance ensures precise bearing surfaces and component positioning. The flat head with hex drive allows for flush mounting in confined spaces, and the Rockwell B55 hardness maintains dimensional stability under load. Ideal for rotating assemblies, pivot points, and precision guides, this shoulder screw solves alignment challenges while offering the durability needed for continuous operation in demanding environments.
Specification Summary & Compliance
This shoulder screw features precision Class 3A thread fit with UNC coarse thread spacing, ensuring reliable engagement in industrial applications. The shoulder diameter maintains tight tolerance of -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005" for consistent performance. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, this fastener is suitable for global manufacturing requirements while providing the mechanical properties necessary for heavy-duty applications.
