The 3/8-16 x 3/8 size serves shaft, hub, collar, and adjustment assemblies that need an internal hex socket set screw in 18-8 stainless steel. Cone point versions use a cone tip that can indent the mating shaft for strong axial holding in fixed settings, especially when a prepared dimple is part of the design.
Common application reviews include commercial equipment, adjustment assemblies, and fixture plates. For maintenance replacement, the exact thread, length, point style, and hex key size should all match the service record or the original component drawing.
18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material referenced to ASTM F880, used for general atmosphere, moisture exposure, and clean appearance. Cold Headers has supplied specialty socket fasteners since 1962 and supports exact-size sourcing for hard-to-find socket products.
