Value Collection 581347PR Hex Socket Cap Screw 12-24 Unc

Product Description

The VALUE COLLECTION 581347PR is a hex socket cap screw engineered for secure fastening in applications requiring high tensile strength and a low-profile head. Sized at 12-24 UNC with a 2.5-inch length under head, this screw is partially threaded and driven with a 5/32-inch hex key. Constructed from alloy steel with a black oxide finish, it resists corrosion and reduces light reflection in service environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and mechanical assembly work across industrial and commercial settings. Machinists, millwrights, and maintenance technicians are the primary installers.

This fastener is suited for machine assembly, fixture building, tooling, and general mechanical fabrication where a recessed drive and a clean head profile are required. The 12-24 UNC thread pitch is a common choice for medium-duty metal-to-metal connections in tapped holes on steel, aluminum, and cast components. The partial thread design allows for greater clamping force by keeping the unthreaded shank through the clearance hole. Minimum order quantity is 10 units, sold in single-piece package quantities.

Key Features

• 12-24 UNC thread size for common medium-duty tapped hole applications
• 2.5-inch length under head, partially threaded for improved clamping performance
• 5/32-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduced surface reflectivity
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard-dimension hex socket cap screw for use in tapped through-holes or blind holes machined to 12-24 UNC thread specifications in metal assemblies and fixtures.

Installation Notes

Installation is performed using a 5/32-inch hex key or Allen bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the torque capacity of the alloy steel screw or the base material. Follow applicable ASME and ASTM guidelines for fastener installation in structural or load-bearing assemblies.
