Professional Applications & Engineering Value

This Nylon 6/6 plastic shoulder screw is engineered to address common industrial challenges like corrosion, electrical insulation, and lightweight assembly requirements. Its socket head design with a hex drive ensures secure tool engagement, reducing slippage during installation in automated or manual settings. The 1 1/2" shoulder length provides a stable bearing surface for rotating components, such as in machinery, pivots, or spacers, preventing misalignment and extending equipment life. Made from temperature-resistant Nylon 6/6, it performs reliably in environments ranging from freezing to moderate heat, while the UNC coarse threads offer quick assembly and high vibration resistance. Ideal for precision applications in electronics, automotive, and packaging industries, this screw enhances durability without the weight or conductivity of metal alternatives.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder diameter tolerance is -0.012" to -0.002", and shoulder length tolerance is -0.015" to 0.015", ensuring precise assembly. It is manufactured in compliance with RoHS 3 (2015/863/EU) regulations, confirming it is free of hazardous substances, and operates effectively within a -40° to 185° F temperature range for broad industrial use.
