It features a 3\/4-10 UNC thread with a 2-3\/4 inch length under head and a square neck that locks the bolt in place when drawn into a mating hole, preventing rotation during installation. The uncoated bright finish leaves the steel surface bare, making it suitable for applications where additional plating or coating will be applied. This bolt is fully threaded along its shank and conforms to SAE J429 standards. It is a single-unit fastener suited for structural, mechanical, and fabrication work requiring a high-grade, reliable connection.\u003c\/p\u003e\n\u003cp\u003eCarriage bolts in this size and grade are commonly used in heavy structural assemblies, timber connections, machinery mounting, and industrial fabrication. The Grade 8 rating makes this bolt appropriate for high-load, high-stress applications where a standard Grade 5 fastener would be insufficient. Professionals working in construction, steel fabrication, and equipment maintenance regularly specify this bolt configuration for joints that demand consistent clamping force and shear resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC fully threaded shank for full thread engagement\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inch length under head for precise fitment in structural assemblies\u003c\/li\u003e\n  \u003cli\u003eSquare neck design prevents bolt rotation during nut tightening\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish compatible with post-installation coating or plating\u003c\/li\u003e\n  \u003cli\u003eConforms to SAE J429 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC carriage bolt for use in structural and mechanical assemblies requiring a 3\/4-10 thread pattern and Grade 8 alloy steel strength rating.

Power down and de-energize any adjacent equipment before beginning fastener work in mechanical assemblies. The square neck must be fully seated into the mating material to prevent spinning during torque application. Always use a Grade 8 compatible nut and hardened washer to match the bolt grade and avoid joint slippage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated \/ Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 218168MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695839248690,"sku":"218168MSC","price":19.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94ee77dad00547d98ed0becb32696267_93ff8b8d-0f8a-4876-a166-fae894de407a.jpg?v=1788338682","url":"https:\/\/voomisupply.com\/products\/value-collection-218168msc-carriage-bolt-3-4-10-2-3-4-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
