The VALUE COLLECTION 88547781 is a flat socket cap screw designed for applications requiring a low-profile, flush-mount fastener with high tensile strength. Manufactured from alloy steel with a black oxide finish, this screw features a 5/16-inch hex socket drive and a 1/2-13 UNC thread pattern. It is fully threaded along its 1-inch overall length, making it suitable for through-hole assemblies where full thread engagement is required. The black oxide finish provides mild corrosion resistance and reduces light reflection. This fastener is installed by maintenance technicians, millwrights, and mechanical contractors working on machinery, fixtures, and structural assemblies.
This flat socket cap screw is used in industrial and commercial applications where a countersunk, flush surface is needed. The hex socket drive allows for installation in recessed or tight-clearance locations using a standard hex key or Allen driver. Fully threaded construction suits thinner materials and through-bolt configurations. Typical applications include machine guards, brackets, enclosures, and equipment frames requiring a clean, snag-free fastener profile.
Designed as an OEM-style replacement or standard fastener for use in machinery, fixtures, and assemblies requiring a 1/2-13 UNC flat socket cap screw with a 1-inch overall length.
Installation requires a 5/16-inch hex key or Allen driver. A properly sized countersunk hole is required to seat the flat head flush with the mating surface. Verify thread engagement depth before final torque. Follow applicable mechanical and structural fastener standards for torque guidelines based on alloy steel grade and joint material.
