4-40 x 5/16 Brass Tip 18-8 Stainless Steel Socket Set Screw is selected when a brass tip is needed to bear on a shaft, stop, or finished component with less marking risk. A brass tip can suit assemblies that need a nonferrous contact face with an 18-8 stainless screw body.
Electrical enclosure hardware and control-panel mechanisms use the headless form where covers need clearance. Internal socket access keeps the screw headless for compact adjustment points.
For maintenance, production, and distributor sourcing, Cold Headers can help verify size and tip data. Check the 4-40 x 5/16 thread, threaded length, tip length, tip diameter, mating material, and drive access against the drawing. When thread friction is needed instead of soft contact, 18-8 Set Screws with Nylon Insert solve a different task.
