Value Collection 88547344 Set Screw 5/16-18 X 5/16 in Cup Point 25pk

Product Description

The VALUE COLLECTION 88547344 is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies where a flush or recessed installation is required. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to shear forces. The 5/16-18 UNC thread and 5/16-inch overall length make it well suited for shaft-to-hub connections, collars, and similar applications. The 5/32-inch internal hex drive accepts a standard hex key for controlled installation torque. Sold in packs of 25, this SKU is appropriate for service stock, production runs, or repair kits.

Cup point set screws are widely used across HVAC equipment, pump assemblies, fan wheel hubs, and general mechanical equipment. The cup point geometry bites into the mating surface to resist rotational and axial movement without requiring a through-hole or nut. This geometry is preferred when moderate holding power is needed and slight marking of the shaft surface is acceptable. Installation is performed by maintenance technicians, millwrights, and HVAC service professionals using a 5/32-inch hex key.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• Cup point geometry provides reliable grip on shaft or mating surface
• 5/16-18 UNC thread standard for broad tool and tap compatibility
• 5/32-inch internal hex drive accepts standard hex keys and T-handle drivers
• 5/16-inch overall length suits shallow boss and collar applications

Compatibility

Designed as a standard 5/16-18 UNC cup point set screw suitable for use in mechanical assemblies, shaft collars, fan hubs, pulleys, and similar components requiring a headless fastener with internal hex drive.

Installation Notes

Installation is performed using a 5/32-inch hex key or Allen driver. Ensure the mating shaft and collar threads are clean and free of debris before installation. De-energize and lock out all rotating equipment before accessing set screw locations. Do not exceed the torque rating of the fastener or the thread engagement depth of the receiving component.
