The VALUE COLLECTION NT-51618-375-SS is a 5/16-18 x 3/8 inch hex-drive set screw with a soft nylon tip point, manufactured from Grade 18-8 stainless steel. Set screws in this configuration are used to secure a component — such as a collar, gear, or pulley — onto a shaft without a protruding head. The hex socket drive accepts a standard hex key (Allen wrench), and the nylon tip protects the mating surface from marring or scoring during tightening. This combination of corrosion-resistant stainless steel body and soft tip point suits installations where shaft surface integrity and resistance to moisture or mild chemicals are both priorities.
This set screw is suited for light industrial, mechanical, and HVAC-adjacent applications where a non-damaging tip is required against a hardened or finished shaft. Typical installation scenarios include motor shaft collars, fan hubs, valve stems, and equipment assemblies in commercial or residential mechanical rooms. The UNC/UNF-compatible 5/16-18 thread standard provides broad fitment across common threaded components.
Designed as a standard 5/16-18 UNC hex-drive soft-tip set screw for use in mechanical assemblies requiring a non-marring fastener in a corrosion-resistant stainless steel body.
Installation is typically performed by a millwright, HVAC mechanic, or general maintenance technician using a properly sized hex key. De-energize and lock out any equipment before removing or installing set screws on rotating components. Do not overtighten — the nylon tip can deform or extrude if excessive torque is applied. Ensure the mating threaded bore is clean and free of debris before installation.
