It features a 5\/8-11 UNC thread and measures 4.5 inches in length under the head. Constructed from Grade 8 alloy steel with a zinc trivalent chromate finish, this bolt delivers strong corrosion resistance alongside the elevated tensile strength required by SAE J429. The square neck below the domed head locks into place as the nut is tightened, preventing rotation without a wrench on the bolt itself. This makes it a practical choice wherever a clean, low-profile head is needed on the fastened surface.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is suited for wood-to-metal and metal-to-metal connections in construction framing, equipment mounting, and general fabrication work. The fully threaded shank allows the nut to be positioned anywhere along the thread length, offering flexibility in joint thickness. Grade 8 alloy steel construction makes it appropriate for load-bearing connections where standard zinc-plated hardware is insufficient. It is commonly installed by maintenance technicians, millwrights, ironworkers, and general contractors working to inch-standard specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets SAE J429 for high-tensile fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc trivalent chromate finish provides corrosion resistance without hexavalent chromium compounds\u003c\/li\u003e\n  \u003cli\u003eSquare neck under the dome head resists rotation during nut installation\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank allows nut positioning anywhere along the 4.5-inch thread length\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread standard ensures broad compatibility with inch-standard hardware\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging suitable for individual replacement or low-quantity purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series carriage bolt compatible with any 5\/8-11 UNC nut and washer hardware used in structural, framing, or fabrication assemblies requiring Grade 8 tensile strength.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this carriage bolt by inserting it through the pre-drilled hole and seating the square neck firmly into the material to prevent rotation. Tighten the nut from the opposite side using a standard wrench or socket. Power down or de-energize any adjacent equipment before working in the installation area.
