Value Collection 704474PR Set Screw 3/8-16 X 1 in Cone Point Ss

Product Description

The VALUE COLLECTION 704474PR is a cone point set screw designed for secure, positive locking in mechanical assemblies where the fastener must bite into or indent a mating surface. Manufactured from Austenitic Grade A2 stainless steel, this screw provides reliable corrosion resistance in wet, outdoor, or chemically exposed environments. The 3/8-16 UNC thread runs the full 1-inch overall length, and the 3/16-inch internal hex drive is engaged with a standard hex key. This fastener meets ASME/ANSI B18.3 and ASTM F880 standards, making it suitable for precision and industrial applications where dimensional conformance is required. Machinists, millwrights, and maintenance technicians are the primary installers.

Cone point set screws are used in shaft-to-hub connections, collar locking, and positioning applications across general industrial, HVAC equipment assemblies, and mechanical power transmission. The cone point geometry creates a permanent or semi-permanent indent in the mating shaft, preventing axial and rotational movement under load. This screw is appropriate for both new assembly work and field repair where the original fastener must be replaced with a corrosion-resistant equivalent. It is sold individually with a minimum order quantity of 5 pieces.

Key Features

• Cone point geometry bites into mating surface for positive axial and rotational locking
• Austenitic Grade A2 stainless steel construction for corrosion resistance
• 3/8-16 UNC thread form for broad compatibility with standard tapped holes
• 3/16-inch hex drive accepts standard hex keys and T-handle drivers
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and material standards
• 1-inch overall length suits medium-depth collar and hub applications

Compatibility

Designed as a standard 3/8-16 UNC cone point set screw replacement or new-installation fastener for mechanical assemblies requiring an ASME/ANSI B18.3 and ASTM F880 conforming stainless steel fastener.

Installation Notes

Installation requires a 3/16-inch hex key or Allen-style driver; ensure the driver is fully seated before applying torque to avoid rounding the drive recess. Verify the tapped hole is clean and free of debris before threading the screw in by hand to confirm proper thread engagement. Power down any rotating machinery and lock out energy sources before servicing set screws in shaft or collar applications. Do not reuse a cone point set screw that has been previously seated, as the point geometry may be deformed and locking effectiveness reduced.
