Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in industrial assemblies. The 316 stainless steel material provides excellent resistance to corrosion from chemicals, saltwater, and extreme temperatures, making it ideal for marine, chemical processing, and food machinery applications. The black oxide finish not only adds an extra layer of corrosion protection but also reduces galling and wear during repeated disassembly. The hex socket drive allows for secure, high-torque fastening in tight spaces, while the precisely manufactured shoulder acts as a pivot, spacer, or bearing surface, ensuring accurate component alignment and reducing wear on mating parts. This combination of high tensile strength and Class 5g6g thread fit ensures reliable performance in dynamic and high-vibration environments, providing long-term operational stability and reducing maintenance needs.

Specification Summary & Compliance

This metric shoulder screw features an M5x0.8 mm coarse thread with a Class 5g6g thread fit for precise tolerance.
