1/2-13 x 5/8 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert helps address both component slip and screw back-out in one specified item. This double-lock arrangement separates the shaft-holding role of the cup point from the thread-locking role of the nylon insert. For final material selection, consider moisture, cleaning exposure, mating material, and whether 18-8 is suitable for the service conditions.
This size is often reviewed for pulleys and sprockets in humid plants, light drives, and hub retention when stainless material and thread locking are both specified. For 316 stainless with a nylon insert, treat the requirement as a non-catalog request that Cold Headers can quote.
Cold Headers supports hard-to-find socket set screw sourcing, including uncommon lengths and nylon-insert configurations. Review the thread size, length, hex key size, point style, and set-screw pellet location before matching the part to a service record or drawing.
