Value Collection 111187PR Set Screw 10-24 X 5/8 in Grade 8

Product Description

The VALUE COLLECTION 111187PR is a 10-24 x 5/8 inch knurled cup point set screw manufactured from Grade 8 alloy steel. Set screws of this type are headless fasteners used to secure a component - such as a collar, gear, or pulley - against a shaft by applying direct point pressure. The knurled cup point provides enhanced grip and resistance to loosening under vibration. Drive engagement is through a 3/32 inch internal hex socket, requiring a standard hex key for installation and removal. This fastener is manufactured to ASME/ANSI B18.3 and ASTM F912 standards, ensuring dimensional consistency and mechanical integrity across production lots.

This set screw is suited for mechanical assembly applications in HVAC, refrigeration, electrical, and general industrial equipment where shaft-mounted components must be held firmly in position. Typical use cases include securing blower wheel hubs, motor shaft collars, and similar rotating or stationary assemblies. The 10-24 UNC thread form is a common size in light-to-medium duty mechanical assemblies. The knurled cup point is particularly effective on shafts where a permanent or semi-permanent bite into the shaft surface is acceptable. These fasteners are sold in quantities consistent with the stated minimum order quantity.

Key Features

• Knurled cup point for improved torque resistance and shaft grip under vibration
• Grade 8 alloy steel construction for high tensile and torsional strength
• 10-24 UNC thread form - common in light and medium duty mechanical assemblies
• 3/32 inch internal hex drive compatible with standard hex keys
• Manufactured to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Overall length of 5/8 inch suits shallow-to-moderate engagement depth requirements

Compatibility

Designed as an OEM-style replacement or maintenance stock fastener for mechanical assemblies using 10-24 UNC threaded set screw positions with a knurled cup point specification.

Installation Notes

Set screws of this type are installed by qualified mechanical or HVAC technicians using a 3/32 inch hex key. Always de-energize and lock out the equipment before accessing shaft-mounted components. Do not overtighten - excessive torque can strip the internal hex socket or damage the mating shaft surface. Confirm thread engagement depth is sufficient for the assembly before applying final torque.
