The VALUE COLLECTION 581611PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and structural connections. It features a 9/16-12 UNC thread size with a 1-1/2 inch length under head and is fully threaded along its entire shank. The 7/16 inch hex drive accepts a standard Allen or hex key for installation. Constructed from alloy steel with a black oxide finish coating, this fastener delivers corrosion resistance and a clean, low-reflectance appearance. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding load and torque requirements in industrial and trade settings.
This screw is used wherever high-tensile socket cap fasteners are required, including machine tool frames, hydraulic components, jig and fixture assemblies, and general industrial fabrication. The fully threaded design maximizes thread engagement across the clamped material stack. It is appropriate for both original equipment manufacturing and maintenance or repair operations across a broad range of metalworking and mechanical service environments.
Designed as a standard 9/16-12 UNC hex socket cap screw for use in any application requiring ASME/ANSI B18.3 and ASTM A574 compliant fasteners.
Installation is performed with a 7/16 inch hex key or Allen driver. Ensure mating threads are clean and free of debris before driving. Do not exceed the torque capacity of the alloy steel fastener, and always follow applicable mechanical design specifications for the assembly. Replacement or installation in structural or pressure-bearing assemblies should be performed by a qualified mechanic or maintenance technician.
