Value Collection R63064128 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R63064128 is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. The 82-degree flat head seats fully into a mating countersink, leaving a smooth surface when properly installed. Sized at 1/4-20 x 1/2 inches overall length with a UNC thread standard, this screw is driven by a 5/32-inch hex socket (Allen) key. The body is machined from 18-8 stainless steel, offering solid corrosion resistance in wet, chemical, or outdoor environments. This fastener is sold individually per manufacturer part number, with a minimum order quantity of 100 pieces.

This screw is suited for mechanical assemblies, equipment enclosures, fixtures, and structural components where a low-profile or flush fastener head is required. The UNC 1/4-20 thread size is one of the most common inch-series fastener specifications, making this screw a standard replacement or build-stock item for maintenance technicians, millwrights, and fabricators working on light to medium-duty assemblies. The 18-8 stainless steel construction makes it appropriate for food-service equipment, marine hardware, HVAC sheet metal, and similar corrosion-sensitive applications.

Key Features

• 82-degree flat head seats flush into standard countersunk holes for a clean, low-profile finish
• 5/32-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 1/4-20 UNC thread is a widely used inch-series standard for broad parts availability
• 18-8 stainless steel construction resists corrosion in wet and mildly chemical environments
• Overall length of 1/2 inch suits shallow countersunk fastening applications

Compatibility

Designed as a standard inch-series flat socket cap screw for any assembly or fixture accepting a 1/4-20 UNC countersunk fastener with an 82-degree head angle.

Installation Notes

Install using a 5/32-inch hex key or Allen bit driver. Ensure the mating hole is machined or drilled to an 82-degree countersink angle to achieve full head seating. Hand-tighten before applying tool torque to avoid cross-threading. When working on energized equipment or pressurized systems, follow all applicable lockout/tagout procedures before accessing fastened panels or covers.
