Value Collection NT-1213-750-SS Set Screw 1/2-13 X 3/4 in

Product Description

The VALUE COLLECTION NT-1213-750-SS is a hex-drive set screw designed for secure, damage-free clamping against shafts, rods, and similar components. It features a soft nylon tip that contacts the mating surface rather than a hardened point, protecting the workpiece from marring or scoring during tightening. The screw is manufactured from Grade 18-8 stainless steel, providing solid corrosion resistance for general industrial, marine-adjacent, and wet-environment applications. Thread size is 1/2-13 UNC with a full threaded length of 3/4 inches. This fastener is installed by machinists, maintenance technicians, and mechanical contractors working with collars, pulleys, and shaft-mounted components.

This set screw is suited for both light industrial and commercial mechanical assemblies where shaft or component surfaces must be protected from the fastener tip. Typical applications include shaft collars, set-collar assemblies, handwheels, and precision positioning fixtures where surface finish on the mating part must be preserved. The nylon tip also reduces the risk of loosening under vibration compared to cup-point or cone-point alternatives, making it a practical choice in rotating equipment maintenance.

Key Features

• Soft nylon tip protects shaft and mating surfaces from marring during installation
• Grade 18-8 stainless steel construction provides corrosion resistance in damp or outdoor environments
• Hex drive accepts standard hex keys for controlled tightening in tight clearances
• UNC 1/2-13 thread standard ensures broad compatibility with inch-series tapped holes
• Full 3/4-inch threaded length maximizes thread engagement in standard collar thicknesses

Compatibility

Designed as a direct-fit replacement or supplemental fastener for any 1/2-13 UNC tapped set screw application requiring a soft-tip or nylon-tip point style in inch-series mechanical assemblies.

Installation Notes

Installation is performed by machinists or mechanical maintenance technicians using a standard hex key or Allen driver sized for the hex socket. Always verify the tapped hole is clean and free of debris before threading in the screw. Apply only hand-snug torque until the nylon tip seats against the shaft to avoid extruding or damaging the tip. Replace the nylon tip insert if visible deformation or loss of tip material is observed during routine inspection.
