Value Collection 88547310 Cup Point Set Screw 3/8-16

Product Description

The VALUE COLLECTION 88547310 is a cup point set screw designed for clamping and positioning applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, it delivers high tensile strength and resistance to shear forces in demanding industrial and trade environments. The screw features a 3/8-16 UNC thread with an overall length of 3/8 inches, driven by a 3/16-inch hex key. Cup point geometry bites into shaft surfaces to resist rotational and axial movement, making it a reliable choice for shaft collars, sprockets, pulleys, and similar components. Machinists, millwrights, and maintenance technicians are the primary installers.

This set screw is suited for use in general industrial machinery, conveyor systems, pump assemblies, and rotating equipment where a compact fastener must lock a shaft or component without a protruding head. The 3/8-16 UNC thread is a standard coarse-thread profile common across North American machinery and equipment. Its compact 3/8-inch length makes it appropriate for thin hubs and shallow threaded bores where a longer fastener would not seat correctly. Packaged in quantities of 13 per unit, it is appropriate for both single-repair and small-batch maintenance tasks.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• Cup point tip bites into shaft surface for positive locking without a protruding head
• 3/8-16 UNC coarse thread — standard North American thread profile
• 3/16-inch hex drive accepts standard hex keys and T-handle wrenches
• Overall length of 3/8 inches suits thin hubs and shallow threaded bores
• Package quantity of 13 supports small-batch maintenance and repair needs

Compatibility

Designed as a standard UNC coarse-thread set screw for use in any threaded bore or shaft collar accepting a 3/8-16 thread, including shaft collars, shaft couplings, sprockets, pulleys, and mechanical stops.

Installation Notes

Set screws of this type are installed by machinists and maintenance technicians using a 3/16-inch hex key or Allen wrench. De-energize and lock out all rotating equipment before servicing any shaft-mounted component. Apply thread-locking compound if vibration is a concern. Do not over-torque the fastener, as cup point set screws in alloy steel can strip threaded bores in softer host materials such as aluminum or brass if excessive force is applied.
