Value Collection 703373PR Set Screw 1/4-20 X 3/4 in Flat Point Ss A2

Product Description

The VALUE COLLECTION 703373PR is a 1/4-20 UNC flat point set screw manufactured from austenitic Grade A2 stainless steel. At 3/4 inches in overall length, it is driven with a 1/8-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F880 standards. Grade A2 stainless provides solid corrosion resistance for applications where mild to moderate chemical or moisture exposure is present. The flat point design distributes clamping force against a shaft without marring the contact surface, making it well-suited for precision or finish-sensitive assemblies. This fastener is sold individually but carries a minimum order quantity of 10 units.

This set screw is used in light to medium-duty mechanical assemblies wherever a threaded collar, hub, or fitting must be locked to a shaft or mating component without a protruding head. Typical applications include HVAC equipment collars, pump shaft retainers, electrical enclosure hardware, and general industrial assemblies requiring a flush or recessed fastener. The 1/4-20 UNC thread size is one of the most common fractional thread forms, making this screw a frequent maintenance and replacement item across trade and light manufacturing environments.

Key Features

• 1/4-20 UNC thread, 3/4 inches overall length for precise sizing in standard fractional-inch applications
• Flat point tip prevents shaft marring and distributes load evenly against the contact surface
• Grade A2 austenitic stainless steel provides corrosion resistance in wet or chemically active environments
• 1/8-inch hex drive compatible with standard hex keys and Allen-type drivers
• Conforms to ASME/ANSI B18.3 and ASTM F880 for dimensional and mechanical compliance
• Sold individually; minimum order quantity of 10 units

Compatibility

Designed as a standard 1/4-20 UNC flat point set screw suitable for any assembly specifying ASME/ANSI B18.3 or ASTM F880 compliance in a 3/4-inch length with a 1/8-inch hex drive.

Installation Notes

Installation is performed with a 1/8-inch hex key or Allen driver; ensure the driver is fully seated before applying torque to avoid rounding the drive cavity. Power down and de-energize any equipment before accessing rotating shafts or live assemblies. Follow applicable mechanical and electrical codes for the equipment being serviced. Do not over-drive the screw, as stainless fasteners are susceptible to galling if excessive force is applied without lubrication.
