Value Collection 63881 Flat Socket Cap Screw 1/2-13 X 3/4 in 25pk

Product Description

The VALUE COLLECTION 63881 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Sized at 1/2-13 UNC thread with an overall length of 3/4 inches, this screw is manufactured from 18-8 stainless steel, providing solid corrosion resistance in wet, outdoor, or chemically exposed environments. The 82-degree flat head seats flush into a countersunk hole, while the 5/16-inch hex socket drive allows secure torque application with a standard hex key or Allen driver. Sold in a package of 25, this fastener is suitable for assembly, fabrication, and maintenance tasks across mechanical, plumbing, and equipment installation work.

This flat socket cap screw fits into countersunk applications in both residential and commercial settings. Common use cases include equipment panel assembly, pump and valve bracket mounting, and general structural fastening where a flush head profile is required. The UNC thread standard makes it compatible with the most widely used inch-series tapped holes found in standard trade and manufacturing applications. The 18-8 stainless steel construction makes it a practical choice for environments where mild to moderate corrosion exposure is expected, such as HVAC equipment enclosures, plumbing panel work, or poolside mechanical installations.

Key Features

• 18-8 stainless steel construction offers corrosion resistance in damp or outdoor conditions
• Pack of 25 units per package, minimum order quantity of 1

Compatibility

Designed for use in standard inch-series countersunk applications requiring a 1/2-13 UNC flat socket cap screw with an 82-degree head angle.

Installation Notes

Installation is typically performed by mechanics, millwrights, plumbers, or HVAC technicians using a 5/16-inch hex key or Allen driver. Ensure the mating hole is properly countersunk to 82 degrees before installation to allow full flush seating of the head. De-energize or shut off all relevant systems before fastening into any live equipment enclosure or mechanical assembly. Do not overtighten stainless steel fasteners, as galling can occur — applying anti-seize compound to the threads is a common preventive measure.
