Value Collection 605221PR Set Screw 1/4-20 3/16in Oval Point

Product Description

The VALUE COLLECTION 605221PR is a 1/4-20 UNC alloy steel set screw with an oval point, designed for use in mechanical assemblies where a component must be secured against a shaft or within a bore without a protruding head. At 3/16 inches in overall length and driven by a 1/8-inch hex key, this fastener is sized for tight spaces and precision applications. Manufactured to Grade 8 alloy steel and conforming to ASME/ANSI B18.3 and ASTM F912 standards, it delivers the clamping force and hardness required in demanding industrial and mechanical service environments. Machinists, millwrights, and maintenance technicians are the primary installers.

This set screw is suited for use in pulleys, collars, gears, couplings, and similar rotating or fixed components where flush or recessed fastening is required. The oval point contacts the mating surface with a rounded tip, reducing shaft damage compared to cup or cone point designs while maintaining reliable holding force. Applicable in general industrial, manufacturing, and mechanical maintenance settings across both light and heavy-duty equipment.

Key Features

• Oval point tip reduces shaft marring compared to cup or cone point alternatives
• 1/4-20 UNC thread for broad tooling and hardware compatibility
• Grade 8 alloy steel construction for high tensile and torsional strength
• 1/8-inch hex drive fits standard hex key sets
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows fully recessed installation flush with the mating component

Compatibility

Designed as a standard 1/4-20 UNC oval point set screw for use in any mechanical assembly that accepts a headless hex-drive fastener of this thread size and overall length.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/8-inch hex key or Allen wrench. Ensure the mating bore or tapped hole is clean and free of debris before threading. Disengage power and lock out all energy sources on rotating equipment before installing or adjusting set screws. Apply thread-locking compound if vibration service is expected and the application permits it.
