Value Collection DHI-24200-006 Cup Point Set Screw 1/4-28

Product Description

The VALUE COLLECTION DHI-24200-006 is a cup point set screw designed to secure collars, hubs, pulleys, and similar components onto shafts without a protruding head. Manufactured from Grade 8 alloy steel, this fastener meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, ASTM A574, and MS16555 standards. The 1/4-28 UNF thread provides fine thread engagement for reliable holding force in applications where vibration resistance matters. The 1/8-inch hex drive accepts a standard hex key or Allen wrench. Weighing 0.012 pounds, this screw is sized for precision assemblies in mechanical, industrial, and maintenance applications.

This set screw is suited for use in mechanical power transmission assemblies, machine tool setups, and general industrial fabrication. The cup point geometry bites into the shaft surface to resist rotational and axial movement. At 1-1/4 inches in length with a 1/4-28 fine thread, it fits threaded bosses and tapped holes common in light-to-medium duty rotating equipment. Maintenance technicians, machinists, and millwrights will encounter this fastener in both OEM assemblies and field repair work across manufacturing and process industries.

Key Features

• Cup point geometry provides a positive bite into shaft material, resisting both rotational and axial movement
• Grade 8 alloy steel construction delivers high tensile strength suitable for demanding mechanical applications
• 1/4-28 UNF fine thread for consistent torque and vibration-resistant engagement
• 1/8-inch hex drive compatible with standard hex keys
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, ASTM A574, and MS16555 standards
• Headless design sits flush or below the surface for clearance-sensitive assemblies

Compatibility

Designed as a standard 1/4-28 UNF cup point set screw for use in any threaded hole conforming to ANSI B18.3 specifications for socket set screws.

Installation Notes

Installation requires a 1/8-inch hex key; ensure the key is fully seated in the drive recess before applying torque to avoid rounding. De-energize and lock out any machinery before servicing components secured by this fastener. Clean and inspect both the threaded hole and shaft surface prior to installation. Do not exceed the thread engagement capacity of the mating material, particularly in softer metals or plastics.
