4-40 x 5/16 Nylon Tip 18-8 Stainless Steel Socket Set Screw is a tip-style 18-8 stainless socket set screw for assemblies where surface condition matters. For light contact on finished components, the nylon tip shifts wear toward the replaceable screw end.
Lead screws, ball screws, and rack adjustments use this style where a bare point would be too aggressive. Internal socket access keeps the screw headless for compact adjustment points.
Check the 4-40 x 5/16 thread, threaded length, tip length, tip diameter, mating material, and drive access against the drawing. Because the tip is added to the working end, the 3A thread fit remains available for close-fitting tapped holes. With stainless collars, moderate drive speed and suitable anti-seize can help reduce galling.
