Professional Applications & Engineering Value
This 18-8 Stainless Steel Shoulder Screw is engineered to address common industrial challenges, such as misalignment and component wear in machinery. The 4-40 UNC coarse thread and 5/32" thread length provide reliable fastening in precision assemblies, while the 1/8" shoulder diameter acts as a pivot or spacer, reducing friction and ensuring proper alignment in rotating parts. Made from corrosion-resistant stainless steel, it withstands exposure to moisture and chemicals, making it ideal for applications in automotive, aerospace, and electronic enclosures. The knurled socket head and hex drive facilitate secure installation, minimizing downtime in production lines and enhancing overall engineering efficiency.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit for high precision, with tolerances including shoulder diameter of -0.004" to -0.002" and shoulder length of -0.005" to 0.005". It adheres to UNC thread standards and 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.
