These machine bolts are designed to adhere facing materials and prevent shear movement across a range of structural connections. The hot-dip or electro-galvanized zinc coating provides corrosion resistance suited for both indoor and outdoor environments. Grade 2 classification makes them appropriate for most general-purpose fastening tasks where high-strength alloy hardware is not required. Each bolt features a standard hex head for use with common wrenches and sockets.\u003c\/p\u003e\u003cp\u003eThese bolts are applicable in wood-to-wood, wood-to-metal, and metal-to-metal assemblies. Typical use cases include framing connections, joist hangers, equipment mounting, and structural panel attachment in light commercial and residential construction. The 50-piece pack quantity supports job-site or shop inventory for repetitive fastening tasks. They are appropriate for use by carpenters, millwrights, general contractors, and maintenance tradespeople working with standard structural materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 2 galvanized construction provides corrosion resistance for general-purpose indoor and outdoor use\u003c\/li\u003e\n\u003cli\u003e3\/8 inches by 4 inches sizing suits medium-duty structural fastening applications\u003c\/li\u003e\n\u003cli\u003eHex head design accepts standard wrenches and sockets for fast installation\u003c\/li\u003e\n\u003cli\u003ePrevents shear movement in wood-to-wood, wood-to-metal, and metal-to-metal connections\u003c\/li\u003e\n\u003cli\u003e50-piece pack quantity reduces restocking frequency on active job sites\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Grade 2 hex nuts and washers of matching finish in standard 3\/8-inch clearance holes across wood, light steel, and structural panel assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePre-drill clearance holes before installation to avoid splitting wood substrates or misaligning metal panels. Use washers and nuts of a similar grade and finish to maintain consistent load distribution and corrosion performance across the joint. A standard ratchet or wrench is sufficient for installation; avoid power-driving beyond snug-tight without a torque reference appropriate to the application. Always consult applicable building codes for structural fastener requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 3\/8 inches x 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 bolts per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 63.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HILLMAN FASTENERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 811590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51558699827506,"sku":"811590","price":476.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f0a9d190dd2d7a92d7e0c27d7eec0e7_8f736ce7-3231-426b-81a7-2d50fa1f42da.jpg?v=1786418345","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-811590-galvanized-hex-bolts-3-8x4-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
