Professional Applications & Engineering Value
This 316 stainless steel shoulder screw with black oxide finish delivers critical corrosion protection in chemical processing, marine, and food equipment applications where moisture resistance is paramount. The Class 3A UNF fine threads provide superior vibration resistance in precision machinery, while the knurled socket head ensures secure tool engagement during assembly. The standard shoulder diameter maintains precise component alignment in rotating assemblies and bearing mounts, eliminating misalignment issues. With Rockwell B79 hardness and high tensile strength, this shoulder screw withstands heavy dynamic loads in automation equipment and industrial machinery, reducing maintenance frequency and downtime.
