Value Collection NT-3816-375-AS Set Screw 3/8-16

Product Description

The VALUE COLLECTION NT-3816-375-AS is a 3/8-16 x 3/8 inch hex-drive set screw with a soft nylon tip point, manufactured from Grade 8 alloy steel. Set screws of this type are used to secure a component — such as a collar, pulley, gear, or sprocket — against a shaft without a protruding head. The hex socket drive accepts a standard hex key for installation. The nylon tip protects the mating shaft surface from galling or marring while still delivering adequate holding force. Grade 8 alloy steel provides the high tensile strength required for demanding mechanical assemblies. Licensed trades and industrial maintenance technicians install these fasteners routinely across HVAC, plumbing, and mechanical system applications.

This set screw is suited for use in light to heavy mechanical assemblies where shaft protection is a priority. The nylon soft tip is particularly appropriate in applications where the shaft finish must be preserved or where vibration could damage a metal cup-point contact. The UNC and UNF thread standard compatibility makes this fastener adaptable across common inch-series threaded bores. Typical applications include motor shaft collars, fan hubs, valve stems, and similar rotating or fixed mechanical components found in residential and commercial mechanical systems.

Key Features

• 3/8-16 thread size with 3/8 inch thread length for compact, flush installation
• Nylon soft tip protects shaft surfaces from galling and cosmetic damage
• Grade 8 alloy steel construction provides high tensile and proof load strength
• Hex socket drive for precise torque application with a standard hex key
• Compatible with UNC and UNF thread standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies using 3/8-16 inch-series threaded bores requiring a soft-tip set screw.

Installation Notes

Installation is performed by mechanical and maintenance technicians using a properly sized hex key. Always de-energize and lock out any rotating equipment before installing or adjusting set screws. Do not overtighten — excessive torque can deform the nylon tip and reduce holding effectiveness. Verify thread engagement is clean and free of debris before seating the fastener.
