Value Collection BT-51618-1-AS Set Screw 5/16-18 X 1 in

Product Description

The VALUE COLLECTION BT-51618-1-AS is a Grade 8 alloy steel set screw with a soft brass tip point, designed for secure fastening applications where surface protection is a priority. Measuring 5/16-18 thread size by 1 inch in length with a UNC/UNF thread standard, this hex-drive fastener is used to lock components onto shafts or within housings without damaging the mating surface. The brass tip deforms slightly under load to grip without marring, making it well-suited for assemblies where the clamped part must be repositioned or protected. Grade 8 alloy steel construction provides high tensile strength for demanding mechanical applications.

This set screw is appropriate for use in mechanical assemblies across industrial, HVAC, and general trade applications. Typical installations include securing pulleys, collars, gears, and hubs to shafts in rotating equipment. The soft brass tip is especially useful when working with hardened or finished shaft surfaces where a cup or cone point would cause unacceptable surface damage. Machinists, millwrights, and general maintenance technicians routinely specify soft-tip set screws for these scenarios.

Key Features

• Grade 8 alloy steel for high tensile strength in demanding mechanical environments
• Soft brass tip protects shaft and mating surfaces from scoring or galling
• 5/16-18 UNC/UNF thread for broad compatibility with standard tapped holes
• Hex drive for precise torque application with standard hex keys
• 1-inch thread length suitable for medium-depth engagement in collars and hubs

Compatibility

Designed as a standard-fit replacement or supplemental fastener for 5/16-18 tapped set screw applications in mechanical assemblies requiring a soft-tip point style.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a properly sized hex key or Allen wrench. De-energize and lock out all rotating equipment before installing or adjusting set screws. Ensure the tapped hole is clean and free of debris before threading the screw in. Do not exceed the torque rating appropriate for the fastener grade and thread size as specified by applicable mechanical standards.
