Value Collection 705368PR Set Screw 1/4-20 X 1/2 in Oval Point

Product Description

The VALUE COLLECTION 705368PR is a 1/4-20 x 1/2 inch oval point set screw manufactured from austenitic Grade A2 stainless steel. Driven by a 1/8 inch hex key, this headless fastener is designed to secure components onto shafts or within bores without protruding above the surface. The oval point tip seats into a mating depression or against a curved surface, distributing load and reducing the risk of shaft damage compared to cup or cone point styles. It conforms to ASME/ANSI B18.3 and ASTM F880 standards, making it a reliable choice for applications requiring dimensional and material traceability. Machinists, millwrights, and maintenance technicians are the primary installers.

This set screw is suited for light-duty shaft locking, collar positioning, and adjustment applications across industrial, HVAC, and mechanical systems where corrosion resistance is a priority. Grade A2 stainless steel performs well in moist or mildly corrosive environments, making it a practical choice over zinc or plain-steel alternatives in exposed or outdoor mechanical assemblies. The UNC 1/4-20 thread is one of the most common coarse-thread sizes in North American fastener applications, ensuring broad compatibility with standard tapped holes.

Key Features

• Oval point tip reduces shaft marring and seats securely in pre-drilled depressions
• Grade A2 austenitic stainless steel provides corrosion resistance in wet or mildly harsh environments
• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 1/8 inch hex drive for precise torque application with a standard hex key or Allen wrench
• Meets ASME/ANSI B18.3 and ASTM F880 standards for dimensional and material compliance
• Headless design sits flush or below surface level, eliminating protrusion hazards

Compatibility

Designed as a standard 1/4-20 UNC coarse-thread set screw for use in any tapped hole meeting that thread specification; suitable for shaft collars, pulleys, knobs, and mechanical assemblies requiring a headless oval point fastener.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/8 inch hex key or L-key. Always power down and de-energize rotating equipment before removing or installing set screws on shafts or couplings. Ensure the mating tapped hole is clean and free of debris before threading in the fastener. Do not exceed the recommended seating torque for the thread size and material as specified by applicable ASME standards.
