Value Collection R63064486 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R63064486 is a flat socket cap screw designed for fastening applications that require a flush or countersunk finish. Manufactured from 18-8 stainless steel, it offers solid corrosion resistance in wet, humid, or mildly corrosive environments. The 1/4-20 UNC thread and 3/8-inch overall length make it a compact, reliable fastener for light structural, mechanical, and equipment assembly work. Drive engagement is through a 5/32-inch hex socket, and the 82-degree flat head seats flush into a standard countersunk hole. This screw is commonly installed by machinists, millwrights, HVAC technicians, and general trade professionals using Allen wrenches or hex-key drivers.

This fastener is suited for residential and commercial mechanical assembly applications where a low-profile, flush-mount fastener is required. Common installation scenarios include panel mounting, bracket attachment, equipment enclosures, and light-duty structural connections in corrosion-prone environments. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor use where mild chemical or moisture exposure is a factor. It follows the Unified National Coarse thread standard, making it broadly compatible with standard 1/4-20 tapped holes.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and humid environments
• 82-degree flat head profile seats flush into standard countersunk holes
• 1/4-20 UNC thread standard for broad compatibility with common tapped holes
• 5/32-inch hex socket drive for secure engagement with standard Allen wrenches
• 3/8-inch overall length suitable for shallow countersunk fastening applications

Compatibility

Designed as a standard-dimension replacement or service fastener for any application requiring a 1/4-20 UNC flat socket cap screw with an 82-degree countersink angle and 3/8-inch overall length in 18-8 stainless steel.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen wrench driver. Ensure the mating hole is properly countersunk to 82 degrees to allow the flat head to seat fully flush. Do not overtighten into soft or thin materials, as stainless steel threads can gall under high torque without proper lubrication. Follow applicable mechanical assembly standards and confirm thread engagement depth before final torque.
