Value Collection 121196PR Set Screw 1/2-13 X 3/4 in Cone Point

Product Description

The VALUE COLLECTION 121196PR is a cone point set screw designed for secure, positive locking in shaft and collar assemblies. Manufactured from Grade 8 alloy steel, it delivers high tensile strength and resistance to vibration-induced loosening. The 1/2-13 UNC thread and 3/4-inch overall length make it suitable for medium-to-heavy-duty fastening applications. A 1/4-inch hex drive accepts a standard hex key for installation. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for both industrial and mechanical trade applications where code-compliant hardware is required.

Cone point set screws are commonly used in power transmission components such as shaft collars, hubs, pulleys, and sprockets. The cone point bites into or seats within a mating dimple on the shaft, providing a strong resistance to rotational and axial movement. This part is suited for mechanical assemblies in HVAC equipment, pumping systems, and general industrial machinery where a permanent or semi-permanent hold is needed.

Key Features

• Cone point geometry seats into shaft dimples for strong rotational and axial hold
• Grade 8 alloy steel construction for high tensile strength and durability
• 1/2-13 UNC thread for compatibility with standard inch-series tapped holes
• 1/4-inch hex drive for use with common hex keys and allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Fractional inch sizing for straightforward measurement and specification

Compatibility

Designed as a standard inch-series set screw for use in any application requiring a 1/2-13 UNC tapped hole with a cone point fastener, including shaft collars, hubs, and mechanical couplings.

Installation Notes

Installation is performed using a 1/4-inch hex key. De-energize and lock out any rotating equipment before servicing shaft or collar assemblies. Ensure the mating shaft has an appropriate dimple or flat to accept the cone point and prevent shaft damage. Follow applicable mechanical and equipment manufacturer guidelines for set screw seating procedures.
