Value Collection R63008642 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION R63008642 is a flat socket cap screw designed for precision fastening applications where a flush or countersunk profile is required. Sized at 2-56 UNC with an overall length of 3/8 inches, it features an 82-degree flat head and a hex socket drive. The fastener is manufactured from 18-8 stainless steel, providing solid corrosion resistance suitable for general-purpose mechanical and structural assemblies. This screw is commonly installed by machinists, maintenance technicians, and trade professionals working on equipment panels, brackets, and assemblies requiring a low-profile fastening solution.

This flat socket cap screw suits light-duty mechanical assemblies where a countersunk seating surface is needed and the fastener head must sit flush with or below the material surface. The 2-56 thread size places this fastener in the small-screw range, making it appropriate for instrument enclosures, electronics housings, precision fixtures, and similar fine-thread applications common in commercial and industrial maintenance environments.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• Hex socket drive for positive torque engagement with Allen-style keys
• 18-8 stainless steel construction resists corrosion in wet or humid environments
• 2-56 UNC thread standard for compatibility with inch-system tapped holes
• Overall length of 3/8 inches suits thin-material and close-tolerance assemblies

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any tapped hole conforming to 2-56 UNC thread specifications.

Installation Notes

Installation requires a correctly sized hex key or Allen wrench matched to the socket drive. Ensure the mating hole is countersunk to 82 degrees for proper head seating before driving the fastener. Power down and de-energize any equipment before performing fastener replacement or assembly work on electrical or mechanical enclosures. Avoid overtightening in small-thread applications, as the 2-56 thread form has limited torque capacity.
