1/2-13 x 3/4 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert is selected where a stainless cup point set screw also needs a thread-locking pellet. This double-lock arrangement separates the shaft-holding role of the cup point from the thread-locking role of the nylon insert. Slight magnetism from cold working can be normal for 18-8 stainless, so verify the material requirement against the actual assembly.
In packaging equipment, indexing stops, and machine adjustments, the internal hex drive allows adjustment from the end of the tapped hole. For 316 stainless with a nylon insert, treat the requirement as a non-catalog request that Cold Headers can quote. Cup point contact can mark the shaft, so confirm that localized contact is acceptable for the mating surface.
For distributors, OEM sourcing, and maintenance work, Cold Headers can help match the thread, length, point style, material, and insert location. 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.
