Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, automation systems, and heavy-duty assemblies. The 1/2"-13 UNC coarse threads provide robust fastening in high-vibration environments, while the precisely machined 1/2" shoulder diameter ensures accurate component positioning, reducing wear and misalignment. The knurled head and 1/4" hex drive facilitate quick, secure installation in confined spaces, making it ideal for applications like rotating shafts, pivots, and jigs. With its high tensile and shear strength, this shoulder screw delivers reliable performance in demanding industrial settings, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Key dimensions include a shoulder diameter of 1/2" (tolerance: -0.004" to -0.002") and shoulder length of 1/4" (tolerance: -0.005" to 0.005"), ensuring precise assembly. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmental and safety regulations in global industrial applications.
