Value Collection R63064684 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION R63064684 is a flat socket cap screw designed for use in fastening applications that require a flush or countersunk head profile. Sized at 5/16-18 UNC thread with an overall length of 1-3/4 inches, this fastener features an 82-degree flat head and a 3/8-inch hex socket drive. It is manufactured from 18-8 stainless steel, providing corrosion resistance suitable for both indoor and outdoor service environments. Maintenance technicians, millwrights, and general tradespeople use this type of fastener when a standard cap screw head would protrude above the mating surface.

This flat socket cap screw is appropriate for mechanical assemblies, equipment panels, fixtures, and structural connections where a low-profile or flush-mount fastener is required. The UNC thread form is the standard inch-series coarse thread, making it compatible with the widest range of tapped holes and threaded inserts in that size class. It is well suited for general industrial, HVAC equipment, plumbing fixture, and electrical enclosure applications where stainless steel is specified for corrosion resistance.

Key Features

• 82-degree flat head seats flush or below the mating surface when used with a properly countersunk hole
• 3/8-inch hex socket drive for use with a standard hex key or Allen bit
• 18-8 stainless steel construction resists rust and corrosion in wet or humid service conditions
• 5/16-18 UNC thread — standard inch-series coarse thread for broad tap and insert compatibility
• Overall length measured as specified: 1-3/4 inches

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any tapped or threaded insert hole sized 5/16-18 UNC requiring an 82-degree countersunk flat head fastener.

Installation Notes

Installation requires a matching countersunk hole bored to 82 degrees for proper head seating. Use the appropriate 3/8-inch hex key or Allen drive bit and tighten to the torque specification listed in the applicable equipment service documentation. Power down or de-energize any equipment before fastener service on electrical or HVAC enclosures. Avoid cross-threading by starting the fastener by hand before applying drive torque.
