Value Collection 151330PR Set Screw 3/8-24 X 3/8 in Flat Point

Product Description

The VALUE COLLECTION 151330PR is a flat point set screw designed for secure, non-marring clamping and locking applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to shear forces. It features a 3/16-inch internal hex drive for use with a standard hex key. The 3/8-24 UNF thread provides fine-thread engagement for precise adjustment and superior holding power in metal-to-metal contact situations. Machinists, millwrights, and maintenance technicians install these screws into collars, hubs, pulleys, and shaft assemblies where a recessed, flush-mount fastener is required.

This set screw is suited for use in industrial machinery, HVAC equipment drive assemblies, motor shaft collars, and mechanical power transmission components. The flat point style applies clamping pressure over a broad contact area, making it appropriate for hardened or finished shaft surfaces where a cupped or cone point would cause damage. It is commonly specified in both original-equipment manufacturing and field-repair applications across light and heavy industrial environments.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• 3/8-24 UNF fine thread for precise torque control and tight engagement
• Flat point design distributes clamping load without marring shaft surfaces
• 3/16-inch hex drive accepts standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Overall length of 3/8 inches for compact, flush installation

Compatibility

Designed as a standard UNF set screw for use in any threaded bore or collar accepting a 3/8-24 thread. Confirm thread pitch, engagement depth, and point style requirements before installation.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated hex key or T-handle driver. Ensure the mating threaded bore is clean and free of debris before threading the screw. Apply thread-locking compound if vibration loosening is a concern, per the equipment manufacturer's specifications. Do not overtighten, as Grade 8 alloy set screws are strong but the mating bore threads may be softer material.
