Value Collection 409222BR Set Screw 3/4-10 X 5-1/2in Cup Point

Product Description

The VALUE COLLECTION 409222BR is a cup point set screw designed for mechanical assemblies requiring a secure, non-protruding fastener. Manufactured from Grade 2 alloy steel with a 3/4-10 UNC thread and a length of 5-1/2 inches, this set screw uses a square drive for positive torque engagement and minimal cam-out. Cup point geometry creates an indentation in the mating shaft or surface, locking the fastener in place under load. Machinists, millwrights, and mechanical contractors install this type of fastener in collars, hubs, pulleys, and similar shaft-retention applications.

This set screw is suited for industrial and commercial mechanical assemblies where a flush or recessed fastener is required. The 3/4-10 coarse thread pitch offers strong engagement in standard tapped holes, making it appropriate for medium-to-heavy duty shaft collars, sprocket hubs, and power-transmission components. Installation is performed with a square drive wrench or bit sized to the drive socket of this fastener.

Key Features

• Cup point geometry seats into the mating surface for positive shaft retention under dynamic load
• Square drive allows high torque input with reduced risk of drive recess damage
• 3/4-10 UNC coarse thread provides strong engagement in standard tapped steel or cast iron
• Grade 2 alloy steel construction offers solid mechanical strength for general industrial use
• 5-1/2-inch length accommodates deep or thick hub engagement requirements
• Fractional inch sizing and UNC thread standard align with common North American mechanical specifications

Compatibility

Designed as a standard UNC-thread cup point set screw for use in any tapped 3/4-10 hole requiring a square drive fastener in shaft collars, pulleys, hubs, or similar mechanical components.

Installation Notes

Installation and removal should be performed by a qualified millwright, machinist, or mechanical technician using a properly sized square drive tool. De-energize and lock out all rotating equipment before servicing any shaft-retention fastener. Apply thread-locking compound or anti-seize as required by the application and governing maintenance specifications. Do not exceed the rated torque capacity of the drive recess to avoid fastener damage.
