Sized at 3\/4-10 UNC thread with a 2-inch length under head, this bolt features a square neck that locks into place against the mating surface to prevent rotation during tightening. Manufactured from Grade 8 alloy steel with a bright uncoated finish, it meets SAE J429 standards for mechanical properties. Machinists, millwrights, maintenance technicians, and general contractors install this type of hardware where high-load, vibration-resistant connections are required.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is suited for heavy-duty structural assemblies in residential, commercial, and industrial settings. Typical applications include wood-to-wood connections, machinery mounting, conveyor frames, and equipment fabrication. The fully threaded shank provides maximum thread engagement across the full 2-inch length under head, making it well-suited for thin-stack assemblies or applications where adjustable clamping depth is needed. It is sold and packaged as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread size for high-load fastening applications\u003c\/li\u003e\n\u003cli\u003e2-inch fully threaded length under head provides full thread engagement throughout the shank\u003c\/li\u003e\n\u003cli\u003eSquare neck design resists rotation during nut installation without a secondary tool on the bolt head\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction meets SAE J429 mechanical standards\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for dry or controlled indoor environments\u003c\/li\u003e\n\u003cli\u003eInch-system dimensions for compatibility with standard UNC hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-fitment carriage bolt for any structural or mechanical assembly specifying a 3\/4-10 UNC, 2-inch, fully threaded, Grade 8 square-neck carriage bolt per SAE J429.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by maintenance technicians, millwrights, or construction tradespeople using standard hand or power tools. Always de-energize or lock out equipment before installing or removing fasteners in mechanical assemblies. The square neck must seat fully into the mating hole to prevent bolt rotation — use an appropriately sized square-hole plate or fitting where required.
