Value Collection 703363PR Set Screw 1/4-20 X 1/4 in Flat Point Ss A2

Product Description

The VALUE COLLECTION 703363PR is a 1/4-20 UNC flat point set screw manufactured from Austenitic Grade A2 stainless 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 direct contact pressure at the point. The flat point style distributes clamping force across a flat surface without marring the shaft, making it well suited for softer shaft materials or applications requiring a flush-seated hold. Driven with a 1/8 inch hex key, this fastener meets ASME/ANSI B18.3 and ASTM F880 standards. Licensed tradespeople and maintenance technicians working on mechanical assemblies, HVAC equipment, and rotating components are the primary installers of this fastener type.

This set screw is used in light to medium-duty mechanical assemblies across residential and commercial applications. Common install scenarios include securing shaft collars on blower wheels, locking pulleys on motor shafts, and fixing couplings in plumbing and HVAC systems. The 1/4-20 thread size and 1/4 inch overall length make this a compact fastener suited for tight clearance installations. A2 stainless steel provides good corrosion resistance, making this appropriate for damp or mildly corrosive environments such as equipment rooms, mechanical chases, and light outdoor enclosures.

Key Features

• Flat point tip distributes clamping load without damaging shaft surfaces
• Austenitic Grade A2 stainless steel provides solid corrosion resistance in wet or humid environments
• 1/8 inch hex drive for use with standard hex keys or Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and performance standards
• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• Compact 1/4 inch overall length suits tight-clearance shaft collar and coupling applications

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 1/4-20 UNC flat point set screw with a 1/8 inch hex drive.

Installation Notes

Installation is performed by qualified mechanical, HVAC, or maintenance technicians familiar with fastener torque requirements and shaft assembly procedures. De-energize and lock out all equipment before accessing rotating components or shaft assemblies. Use a correctly sized 1/8 inch hex key to avoid rounding the drive socket. Inspect the mating tapped hole for damage or contamination before installation to ensure full thread engagement.
