Value Collection R63000263 Set Screw 1/4-20 X 1/2 in Cup Point Ss 316

Product Description

The VALUE COLLECTION R63000263 is a 1/4-20 UNC cup point set screw manufactured from Grade 316 stainless steel. Set screws are headless fasteners used to secure a component - such as a collar, gear, or pulley - against a shaft by applying direct clamping force at the point. The cup point configuration bites into the mating surface for positive retention. At 1/2 inch overall length, this fastener is suited for light to medium-duty clamping applications where corrosion resistance is a priority. Installation requires a 1/8-inch hex key. Grade 316 stainless steel provides strong resistance to chlorides and oxidizing environments, making this screw appropriate for marine, chemical, food-processing, and outdoor industrial settings.

This set screw is used across a wide range of mechanical assemblies requiring a flush, headless fastener in corrosive or wet environments. Typical applications include shaft collars, set collar assemblies, valve stems, pump components, and general mechanical hardware in HVAC, plumbing, and industrial installations. The 1/4-20 UNC thread is a common standard size found in both OEM equipment and field-fabricated assemblies. Sold individually, with a minimum order quantity of 100 pieces.

Key Features

• Cup point tip bites into mating shaft surface for positive, vibration-resistant retention
• Grade 316 stainless steel construction for superior resistance to chlorides and corrosion
• 1/4-20 UNC thread is a widely used standard size for broad compatibility
• 1/8-inch hex drive allows installation with a standard hex key in confined spaces
• Headless design sits flush with or below the surface of the parent component
• 1/2-inch overall length suits light to medium-duty clamping and positioning tasks

Compatibility

Designed as a standard 1/4-20 UNC cup point set screw suitable for use in any assembly that accepts a 1/4-20 headless fastener with a 1/8-inch hex drive.

Installation Notes

Installation is performed with a 1/8-inch hex key or Allen wrench; use a calibrated torque driver where the assembly specifies a torque value. Ensure the mating shaft or surface is clean and free of debris before seating the cup point. When installing in pressurized or rotating machinery, follow applicable equipment manufacturer guidelines and relevant industry codes before performing service. Grade 316 stainless fasteners should not be mixed with dissimilar metals in applications where galvanic corrosion is a concern.
