Value Collection 88547542 Set Screw 7/16-14 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION 88547542 is a Grade 8 alloy steel cup point set screw in a 7/16-14 UNC thread, 1/2 inch overall length. Set screws are headless fasteners used to secure a component — such as a pulley, gear, or collar — against a shaft by biting into the shaft surface with the cup point tip. The Grade 8 alloy steel construction provides high tensile strength suited for demanding mechanical assemblies. Drive engagement is made with a 7/32 inch hex key inserted into the socket head. This fastener is installed by machine maintenance technicians, millwrights, and mechanical contractors across a wide range of industrial and commercial applications.

Cup point set screws like the 88547542 are commonly used in rotating machinery, conveyor systems, motor shaft collars, and mechanical drive components where a firm, vibration-resistant grip on a shaft is required. The cup point geometry creates a small indentation in the mating shaft surface, increasing resistance to rotational movement. This style is among the most widely used set screw point types in industrial maintenance and original equipment assembly work.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding applications
• Cup point tip seats into shaft surface to resist rotation and axial movement
• 7/16-14 UNC thread for compatibility with standard inch-series tapped holes
• 1/2 inch overall length suits medium-depth engagement in shaft collars and hubs
• 7/32 inch internal hex drive accepts standard hex keys and L-wrenches
• Sold in a package quantity of 13 with a minimum order quantity of 1

Compatibility

Designed as a standard-dimension replacement or stock fastener for any application requiring a 7/16-14 UNC, 1/2 inch length, cup point set screw with a 7/32 inch hex drive in Grade 8 alloy steel.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 7/32 inch hex key or Allen wrench. De-energize and lock out any rotating equipment before installing or adjusting set screws. Thread the screw into the tapped hole by hand to avoid cross-threading before applying torque with the hex key. Avoid over-driving, which can damage the shaft surface or strip the socket drive.
