Value Collection 121013PR Set Screw 5-40 X 1/4 in Cone Point

Product Description

The VALUE COLLECTION 121013PR is a cone point set screw designed for secure, positive locking in mechanical assemblies where a firm bite into the mating surface is required. Sized at 5-40 UNC thread by 1/4 inch overall length, it is driven with a 1/16 inch hex key. Manufactured from alloy steel to Grade 8, it delivers high tensile and torsional strength suitable for demanding industrial and mechanical applications. It conforms to ASME/ANSI B18.3 and ASTM F912 standards. Typical installers include maintenance machinists, mechanical assemblers, and industrial technicians working with set screw collars, shaft hubs, or similar components.

This set screw is used in applications requiring a positive cone point engagement to lock a collar, gear, pulley, or hub to a shaft. The cone point digs into the shaft surface or seats into a matching dimple, resisting axial and rotational movement under load. Suitable for light to medium duty shafting in general industrial equipment, small motors, and precision mechanical assemblies. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• Cone point geometry provides positive shaft engagement and strong axial holding force
• 5-40 UNC thread by 1/4 inch overall length for compact, low-profile installations
• Grade 8 alloy steel construction for high tensile and torsional strength
• 1/16 inch hex drive for use with standard hex keys or Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-fit set screw for mechanical assemblies using 5-40 UNC threaded set screw seats with cone point specifications per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 1/16 inch hex key. Ensure the mating shaft or hub is clean and free of debris before seating the cone point. De-energize and lock out any rotating equipment before servicing components secured by set screws. Do not exceed the rated torque capacity for the thread size, and follow applicable machinery safety standards during assembly.
