5/16-18 x 3/4 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert supports set-screw installations where no external head should project from the assembly. The cup point may leave a witness mark depending on shaft material and installation conditions, while the insert works in the threaded engagement. 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. The nylon element limits service temperature compared with an all-metal screw, so review the service conditions before selection.
Since 1962, Cold Headers has helped industrial buyers locate specialty socket products and replacement 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.
