1/4-20 x 1/2 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.
In food and beverage machinery adjustments, changeover stops, and equipment guards, the internal hex drive allows adjustment from the end of the tapped hole. If an all-metal holding feature is preferred, review Knurled Point 18-8 Socket Set Screws for mechanical ratchet-style grip.
Cold Headers installs the locking pellet in-house on supported socket set screw sizes, with odd-size requests handled through quoting. 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.
