Measuring 5\/16 inch in diameter and 5 inches in length, this fastener is constructed from non-magnetic, passivated stainless steel that resists atmospheric corrosion over the long term. Each bolt ships with two stainless steel hex nuts included. The safe working load is rated at 115 pounds, making it suitable for moderate load-bearing tasks in exposed environments. Tradespeople and contractors working on docks, marine structures, outdoor enclosures, or similar corrosive-environment installations will find this fastener suited to those demands.\u003c\/p\u003e\n\u003cp\u003eThis hook bolt is intended for marine settings and other outdoor applications subject to moisture, salt air, and atmospheric exposure. The passivated stainless steel construction makes it appropriate for coastal installations, waterfront structures, pool equipment mounting, and exterior mechanical or electrical enclosure work where standard carbon steel fasteners would corrode prematurely. The package contains 10 pieces, making it practical for small-batch jobs or service van stocking. It ships in bulk format without individual retail packaging.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction passivated for enhanced corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eNon-magnetic material suitable for sensitive or marine-grade installations\u003c\/li\u003e\n  \u003cli\u003eSafe working load of 115 pounds\u003c\/li\u003e\n  \u003cli\u003eIncludes two stainless steel hex nuts per bolt\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch diameter by 5 inch length for standard hook-bolt applications\u003c\/li\u003e\n  \u003cli\u003ePackaged 10 pieces per unit, bulk format\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for marine and outdoor applications requiring a 5\/16 inch hook bolt with atmospheric corrosion resistance.

Confirm the mounting surface and load path are appropriate for the 115-pound safe working load before installation. Do not exceed the rated working load. In corrosive or submerged environments, verify that all mating hardware is also stainless steel or compatible non-ferrous material to prevent galvanic corrosion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnetic Properties\u003c\/strong\u003e: Non-magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafe Working Load\u003c\/strong\u003e: 115 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: Two stainless steel hex nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Format\u003c\/strong\u003e: Bulk\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N221-713\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51560188117298,"sku":"N221-713","price":70.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d80c3899fbfccd78dab1bfbaa2b763e1.jpg?v=1786448691","url":"https:\/\/voomisupply.com\/products\/national-mfg-n221-713-ss-hook-bolt-5-16x5-inch-115lb","provider":"Voomi Supply","version":"1.0","type":"link"}
