Value Collection 604307PR Set Screw 3/8-16 X 1-1/4 in Cone Point

Product Description

The VALUE COLLECTION 604307PR is a 3/8-16 UNC cone point set screw designed for secure, positive locking in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to shear forces in demanding industrial and trade applications. The cone point geometry bites into the mating surface for a firm, vibration-resistant hold. At 1-1/4 inches in overall length with a 3/16-inch hex drive, it meets ASME/ANSI B18.3 and ASTM F912 standards. Installers drive it with a standard 3/16-inch hex key, making it compatible with common hand tools found in any shop or field kit.

This set screw is suited for use in shaft-to-hub connections, collars, sprockets, pulleys, and similar mechanical assemblies found in HVAC equipment, pump systems, conveyor rigs, and general industrial machinery. The cone point style is the appropriate choice when a permanent or semi-permanent locking action is needed and the mating shaft can accept a small cone-shaped indent. Machinists, millwrights, HVAC technicians, and maintenance professionals commonly install this fastener wherever a reliable set screw connection is required.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• Cone point geometry provides firm bite into mating shaft for vibration resistance
• Grade 8 alloy steel construction for high tensile and shear strength
• 1-1/4 inches overall length suits medium-depth collar and hub applications
• 3/16-inch hex drive works with standard hex keys and L-wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard 3/8-16 UNC cone point set screw for use in any tapped hole meeting ASME/ANSI B18.3 specifications at this thread size and length.

Installation Notes

Install using a 3/16-inch hex key, ensuring the tapped hole is clean and free of debris before threading. De-energize or lock out any equipment before servicing assemblies that contain this fastener. The cone point will indent the mating shaft surface, so confirm the shaft material and application allow for this before installation.
