3/8-16 x 3/4 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert gives a stainless, internal-hex set screw option for collars, hubs, and adjustments. One interface helps hold the collar or hub against movement; the other adds friction in the thread so vibration is less likely to loosen the screw. Slight magnetism from cold working can be normal for 18-8 stainless, so verify the material requirement against the actual assembly.
For packaging equipment, indexing stops, or machine adjustments, check point contact, threaded engagement, and drive access before installation. If an all-metal holding feature is preferred, review Knurled Point 18-8 Socket Set Screws for mechanical ratchet-style grip. For chloride-heavy exposure, 316 stainless with nylon insert should be reviewed as a non-catalog request rather than assumed from this 18-8 listing.
Nylon inserts are installed in-house at the Cold Headers Chicago facility for supported set-screw 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.
