The square neck under the domed head resists rotation as the nut is driven, eliminating the need for a wrench on the bolt side. This fastener meets ASTM A307 standards and is suited for general-purpose structural and mechanical assembly work. Typical installers include carpenters, millwrights, and maintenance technicians working on wood-to-wood or wood-to-metal connections requiring a clean, low-profile bolt head.\u003c\/p\u003e\n\u003cp\u003eThis carriage bolt is used in light structural applications including wood framing, fence construction, playground equipment, and equipment mounting. The zinc plating provides baseline corrosion resistance for indoor and sheltered outdoor environments. The 1\/4-20 UNC thread is one of the most common coarse-thread fastener sizes in inch-standard construction and maintenance applications. Sold in multiples of 100 per minimum order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC coarse thread for broad tool and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head suits standard light-duty structural connections\u003c\/li\u003e\n  \u003cli\u003eSquare neck under head locks into wood or slotted material to prevent spinning during installation\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standard\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in sheltered and indoor environments\u003c\/li\u003e\n  \u003cli\u003eRounded dome head delivers a smooth, low-profile exterior face\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system carriage bolt suitable for general-purpose wood and light metal assembly applications requiring a 1\/4-20 UNC thread and 1-1\/2 inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires drilling a clean through-hole sized to the bolt shank diameter so the square neck seats flush and grips the material without spinning. A flat washer and hex nut are typically used on the bearing side; torque the nut with a standard wrench while the domed head bears against the surface. Power down or de-energize any associated equipment before fastening into panels or enclosures. Follow applicable building codes and project specifications for structural fastener placement and spacing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 1-1\/2 inches\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM A307\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161603\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: 489022PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711408341298,"sku":"489022PR","price":1559.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86ce2e5a60532bb496d4943f02f530dd.jpg?v=1788476311","url":"https:\/\/voomisupply.com\/products\/value-collection-489022pr-carriage-bolt-1-4-20-1-1-2-in-grade-2-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
