Value Collection 88547005 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 88547005 is a fully threaded hex socket cap screw designed for fastening applications that require a flush or low-profile head driven with an internal hex key. It carries a 1/2-13 UNC thread specification with a 2-inch length under head, giving it a solid grip range for medium-to-heavy structural and mechanical assemblies. The body is machined from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection in service environments. This fastener is a standard choice for machine builders, millwrights, pipefitters, and maintenance technicians across industrial and commercial settings.

This screw is suited for use in steel fabrication, equipment assembly, jig and fixture construction, and general mechanical fastening where a clean, recessed-drive fastener is preferred over a hex-head bolt. The 1/2-13 UNC coarse thread engages quickly and holds well in tapped steel and cast iron. It is driven with a 3/8-inch hex key or Allen-type driver, making it accessible in tight clearance situations where a wrench cannot reach. Sold in a package quantity of 3, it is appropriate for both repair work and light-volume production applications.

Key Features

• 1/2-13 UNC coarse thread for fast engagement in tapped steel and cast iron
• 2-inch length under head provides substantial grip depth for structural connections
• Fully threaded shank maximizes thread engagement along the entire fastener length
• Alloy steel construction delivers high tensile strength for demanding mechanical loads
• Black oxide finish offers moderate corrosion resistance and a low-glare appearance
• 3/8-inch hex drive allows installation in confined spaces with a standard hex key

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for use in any tapped hole or threaded insert conforming to the 1/2-13 UNC thread standard in steel, cast iron, or similar materials.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or mechanical assemblers using a 3/8-inch hex key or Allen driver. Always confirm the mating tapped hole conforms to 1/2-13 UNC tolerances before installation. Do not exceed the rated torque capacity of the alloy steel fastener, and avoid cross-threading by starting the screw by hand before applying tool force. Inspect the black oxide finish for damage before use in moisture-exposed environments, as the coating alone does not substitute for a dedicated corrosion-resistant fastener where wet or chemical exposure is sustained.
