Value Collection 409114BR Set Screw 5/8-11 X 1-1/2 Cup Point

Product Description

The VALUE COLLECTION 409114BR is a 5/8-11 UNC cup point set screw designed for mechanical fastening applications where a flush or below-surface installation is required. Manufactured from Grade 2 steel with a bright, uncoated finish, this fastener measures 1-1/2 inches in length, measured under head per standard fractional inch conventions. The square drive provides positive torque transfer and reduces the risk of cam-out during installation. This set screw is suited for securing collars, hubs, pulleys, and similar components to shafts in light-duty mechanical assemblies. Installation is performed by licensed machinists, millwrights, or qualified maintenance technicians.

This set screw is used in residential and light commercial mechanical applications where a recessed fastener is needed to lock rotating or stationary components onto shafts without protruding hardware. The cup point geometry bites into the mating shaft surface to resist rotation and axial movement. Typical installations include HVAC blower wheel hubs, pump impeller collars, fan shaft assemblies, and general industrial equipment maintenance where UNC 5/8-11 thread engagement is specified.

Key Features

• 5/8-11 UNC thread for broad compatibility with standard fractional inch threaded holes
• Cup point geometry bites into shaft surface to resist rotation and axial slip
• Square drive for positive torque engagement and reduced cam-out risk
• Grade 2 steel construction suitable for light-duty fastening loads
• Bright uncoated finish — 1-1/2 inches length measured under head

Compatibility

Designed as a standard UNC 5/8-11 cup point set screw for use in any application requiring a 5/8-11 threaded blind-hole fastener. Consult equipment manufacturer specifications to confirm thread engagement length and point type requirements before installation.

Installation Notes

Installation should be performed by a qualified technician using a properly sized square drive bit or wrench. De-energize and lock out all equipment before servicing any mechanical assembly. Apply appropriate thread-locking compound if vibration resistance is required per the equipment manufacturer's guidelines. Torque to the value specified by the equipment OEM — do not exceed the fastener grade rating.
