The VALUE COLLECTION 581627PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assembly, tooling, and structural fabrication. Featuring a 9/16-12 UNC thread size and a 4.5-inch length under head, this screw is partially threaded for secure clamping force. The 7/16-inch hex drive accommodates a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and reduced light reflection in finished assemblies. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it a dependable choice for precision and load-bearing applications.
This screw is suited for industrial maintenance, machine shops, OEM assembly, and general manufacturing environments. The 9/16-12 UNC coarse thread is widely used in ferrous metal applications where quick assembly and strong thread engagement are required. The partial threading allows for shank-to-hole contact that helps resist shear loads. Installers in fabrication, millwright, and equipment maintenance trades commonly use this fastener for fixture building, press frames, conveyor systems, and heavy machinery.
Designed as an OEM-style and maintenance-replacement hex socket cap screw for industrial machinery, fixtures, and structural assemblies requiring 9/16-12 UNC threaded fasteners.
Installation requires a 7/16-inch hex key or T-handle Allen wrench; torque to the specification listed in the equipment service documentation for the applicable joint grade. Always inspect the mating threaded hole for damage or contamination before installation. Apply thread lubricant or anti-seize as required by the application or service manual. Follow applicable ASME or equipment manufacturer torque and fastener-replacement guidelines.
