Value Collection BT-3816-250-AS Set Screw 3/8-16x1/4

Product Description

The VALUE COLLECTION BT-3816-250-AS is a 3/8-16 UNC alloy steel set screw with a soft brass tip point, rated Grade 8. Set screws are headless fasteners threaded along their full length and driven with a hex key. They seat into a tapped hole and apply axial clamping force against a shaft, hub, or mating surface. The brass tip protects softer shaft materials from scoring during tightening. At 1/4 inch in thread length, this screw is suited for compact clamping applications where a low-profile fastener is required. Licensed mechanics, millwrights, and maintenance technicians are the primary installers.

This set screw is used in mechanical assemblies where a rotating or sliding component must be locked to a shaft without a protruding fastener head. Typical applications include shaft collars, pulleys, sprockets, gears, and hand wheels. The soft brass tip makes it appropriate for use on hardened or finished shafts where marring must be avoided. It is suitable for both light industrial and heavy-duty mechanical assemblies that require the holding strength of a Grade 8 alloy steel fastener.

Key Features

• Grade 8 alloy steel construction provides high tensile and proof load strength
• Soft brass tip protects shaft surfaces from scoring or galling during installation
• 3/8-16 UNC thread for wide compatibility with standard tapped holes
• Headless hex-drive design sits flush or below the mating surface
• Full-thread length of 1/4 inch for compact, low-profile clamping

Compatibility

Designed as a standard UNC thread replacement or new-installation set screw for mechanical assemblies requiring a 3/8-16 tapped hole and a soft-tip point to protect shaft surfaces.

Installation Notes

Installation requires the appropriately sized hex key for the drive socket. Ensure the mating tapped hole is clean and free of debris before threading in the screw. Torque to the assembly specification for the application — do not overtighten, as brass tip deformation can reduce holding force. Always de-energize and lock out any rotating machinery before servicing fasteners on shaft-mounted components.
