Value Collection 63884 Flat Socket Cap Screw 1/2-13 X 1-1/2 in

Product Description

The VALUE COLLECTION 63884 is a flat socket cap screw designed for fastening applications that require a flush or countersunk finish. Sized at 1/2-13 thread with an overall length of 1.5 inches, this screw features an 82-degree flat head profile and a 5/16-inch hex socket drive. It is manufactured from 18-8 stainless steel, which provides solid corrosion resistance in mildly corrosive environments. The UNC thread standard ensures broad compatibility with standard inch-measurement tapped holes. Installers in HVAC, plumbing, electrical, and general mechanical trades use flat socket cap screws where a protruding head would interfere with mating surfaces or covers.

This screw is suited for residential and commercial mechanical assemblies where a low-profile fastener is required. The hex socket drive allows use in recessed or tight spaces where a standard wrench or screwdriver cannot seat properly. The 18-8 stainless steel construction makes it appropriate for indoor and light outdoor installations where mild moisture exposure is expected. It is sold in multiples of 25 units per minimum order quantity.

Key Features

• 82-degree flat head profile for flush and countersunk mounting surfaces
• 5/16-inch hex socket drive for use with standard Allen or hex keys
• 1/2-13 UNC thread size for compatibility with standard inch-series tapped holes
• 1.5-inch overall length suitable for moderate fastening depth requirements
• 18-8 stainless steel construction provides corrosion resistance in mildly corrosive environments

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 1/2-13 UNC thread and an 82-degree countersunk flat head seating surface.

Installation Notes

Installation is performed by mechanical and maintenance trades using a 5/16-inch hex key or Allen driver. Ensure the mating surface is properly countersunk to an 82-degree angle before driving the screw to avoid head deformation or improper seating. De-energize and depressurize any system before servicing fasteners on pressurized or electrically active assemblies. Do not overtighten stainless steel fasteners, as galling can occur; the use of an appropriate anti-galling lubricant is standard practice.
