Value Collection NT-3816-750-AS Set Screw 3/8-16 X 3/4 in

Product Description

The VALUE COLLECTION NT-3816-750-AS is a Grade 8 alloy steel set screw with a 3/8-16 UNC thread and a 3/4-inch threaded length. It features a hex drive socket and a soft nylon tip point designed to secure components to shafts or housings without marring or damaging the mating surface. The nylon tip distributes clamping load across the contact area, making this fastener well suited for applications where surface finish or material hardness of the shaft must be preserved. Machinists, millwrights, and maintenance technicians working on rotating equipment, pulleys, collars, and precision assemblies are the primary installers of this type of fastener.

This set screw is used in light to medium industrial and mechanical applications where a non-marring hold point is required. The Grade 8 alloy steel body provides high tensile strength and resistance to shear forces in the thread engagement zone, while the replaceable nylon tip prevents galling on soft-metal or finished shafts. Typical installations include shaft collars, sprocket hubs, gear hubs, and adjustment mechanisms in both production machinery and HVAC equipment drive assemblies. Thread standard is UNC, compatible with standard inch-thread tapped holes.

Key Features

• Grade 8 alloy steel construction for high tensile and proof load strength
• Soft nylon tip point prevents marring or galling on shaft surfaces
• Hex socket drive for standard hex key installation and controlled torque application
• 3/8-16 UNC thread standard for compatibility with common inch-thread tapped holes
• Full 3/4-inch threaded length for solid thread engagement depth
• Non-marring tip suits use on finished, soft-metal, or coated shaft surfaces

Compatibility

Designed as a standard inch-thread set screw for use in any tapped hole with a 3/8-16 UNC thread specification. Compatible with shaft collars, hubs, and mechanical assemblies requiring a soft-tip, non-marring fastener in that thread size.

Installation Notes

Installation requires a hex key (Allen wrench) sized for the socket drive. De-energize and lock out all equipment before servicing rotating assemblies or drive components per applicable OSHA lockout/tagout procedures. Do not overtighten, as the nylon tip can deform or shear under excessive torque. Inspect the nylon tip for wear or compression set periodically and replace the fastener if the tip is damaged or missing.
