The bolt measures 3\/4 inches in length under the head with a head diameter ranging from 1.0000 to 1.0310 inches. Manufactured from 1006-1050 carbon steel with a zinc-plated finish, it resists corrosion in typical indoor and light industrial environments. This fastener conforms to ANSI\/ASME B18.5 standards, making it a reliable choice for engineers, maintenance technicians, and trade professionals who specify to standard dimensions.\u003c\/p\u003e\n\u003cp\u003eStep bolts are commonly used in steel construction, conveyor systems, and equipment mounting where a wide, low-profile head is needed to spread clamping load across a broad surface. This 5\/16-18 size is suited for light-to-medium duty assemblies in residential, commercial, and industrial settings. The UNC thread form is compatible with standard inch-series nuts and tapped holes. Installation is straightforward for millwrights, ironworkers, electricians, and general maintenance trades working with standard inch hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.5 step bolt standard for consistent dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003e1006-1050 carbon steel construction for reliable tensile strength in general-duty applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in dry and mildly humid environments\u003c\/li\u003e\n  \u003cli\u003eLarge head diameter (1.0000 to 1.0310 inches) distributes clamping load over a wider bearing surface\u003c\/li\u003e\n  \u003cli\u003eUNC thread form ensures compatibility with standard inch-series fastener hardware\u003c\/li\u003e\n  \u003cli\u003eWeighs approximately 0.034 pounds per unit, suitable for weight-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ANSI\/ASME B18.5 step bolt for use with 5\/16-18 UNC inch-series nuts and tapped components in general mechanical and structural fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eStep bolts should be installed by qualified tradespeople following applicable fastener torque guidelines for the 5\/16-18 thread class and joint material. Always verify mating hole diameter and thread engagement before final assembly. Zinc-plated fasteners are not recommended for prolonged submersion or highly corrosive environments without additional protective measures. Hand-tighten before applying final torque to avoid cross-threading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.0000 to 1.0310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.5\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: 1006-1050\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Zinc-Plated\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: 0.034 pounds\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: R52001113\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691266933042,"sku":"R52001113","price":1798.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81da27536f51c8ae20500bec7f6c71f7.jpg?v=1788282430","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001113-step-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
