Value Collection 604221PR Set Screw 1/4-20 X 3/16 in Cone Point

Product Description

The VALUE COLLECTION 604221PR is a 1/4-20 cone point set screw manufactured from Grade 8 alloy steel for high-strength clamping and locking applications. At 3/16 inches in overall length, this fastener uses a 1/8-inch hex drive and features a cone point tip that bites into mating surfaces to resist rotation and axial movement. It is manufactured to ASME/ANSI B18.3 and ASTM F912 standards, ensuring dimensional consistency and mechanical performance. Trades and maintenance professionals use this screw when positive locking force is required in collars, hubs, pulleys, and shaft assemblies across mechanical and industrial equipment.

This set screw is suited for use in light industrial, HVAC, plumbing, and general mechanical applications where a compact, headless fastener is needed to secure a component to a shaft or within a threaded bore. The cone point geometry concentrates clamping load at a single contact point, making it well suited for permanent or semi-permanent assemblies. The 1/4-20 UNC thread standard ensures broad compatibility with standard tapped holes found in common mechanical components.

Key Features

• Cone point tip concentrates load for strong shaft engagement and rotation resistance
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 1/8-inch hex drive accepts standard hex keys for installation in confined spaces
• 1/4-20 UNC thread fits widely used standard tapped hole sizes
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Compact 3/16-inch overall length suits shallow-bore and tight-clearance installations

Compatibility

Designed as a standard replacement or stock set screw for any application requiring a 1/4-20 UNC, 3/16-inch overall length cone point set screw with a 1/8-inch hex drive.

Installation Notes

Installation is performed with a calibrated 1/8-inch hex key or Allen wrench; ensure the key is fully seated before applying torque to avoid rounding the drive. Power down or de-energize any equipment before accessing rotating components such as pulleys, collars, or shaft hubs. Verify the mating shaft or bore surface is clean and free of debris before seating the cone point. Follow applicable ASME or equipment manufacturer guidelines for thread engagement and fastener reuse.
