Product Description

The 1/2-13x1-1/8 Fastener is a 1/2-13 UNC Bolt featuring a 1-1/8 Hex Head Screw design, engineered for robust mechanical applications in construction, automotive assembly, and heavy machinery. This fastener combines a 1/2-inch nominal diameter with a coarse 13-thread-per-inch UNC pattern, offering superior grip and tensile strength. The 1.125-inch (1-1/8) shank length ensures secure fastening in medium-thickness materials like steel plates or structural beams. Its hex head design enables compatibility with standard wrenches and sockets, accommodating torque ranges up to 85 lb-ft for reliable installation. Constructed from grade-5 hardened steel, it maintains integrity in temperatures from -50°F to 450°F (-45°C to 232°C) with optional zinc plating for corrosion resistance. While excelling in load-bearing scenarios, its non-electrical nature excludes communication interfaces or power requirements. The hex head's 1.125-inch across-flat dimension provides optimal torque transmission, though it requires adequate clearance space during installation. Typical applications include industrial equipment frames, structural bracing systems, and hydraulic component assemblies where vibration resistance and shear strength are critical.
