The bolt features a 5\/8-11 thread with a fully threaded 2.5-inch shank, giving riggers and ironworkers a secure, positive engagement with the load-bearing structure. Constructed from C-1035 grade steel with a hot dipped galvanized finish, this eye bolt resists corrosion in demanding job-site conditions. It is suited for use by millwrights, rigging crews, and maintenance technicians working with hoists, cranes, and block-and-tackle systems where a permanently oriented straight-pull lift point is required.\u003c\/p\u003e\n\u003cp\u003eThe SP20503 is intended for straight vertical lifting only, which is the standard application for fixed shoulder eye bolts. The shoulder design seats flush against the load surface when fully torqued, distributing stress at the base and preventing rotation under load. This bolt is appropriate for use in structural steel, heavy equipment frames, machinery bases, and similar applications where a permanent or semi-permanent lift point is needed. It is sold individually and packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4,000 lb rated lifting capacity for vertical straight-pull applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded 2.5-inch shank with 5\/8-11 thread size for secure engagement\u003c\/li\u003e\n  \u003cli\u003eShoulder design seats flush against load surface to distribute stress at the base\u003c\/li\u003e\n  \u003cli\u003eC-1035 grade steel construction provides high tensile strength for demanding lift points\u003c\/li\u003e\n  \u003cli\u003eHot dipped galvanized finish for corrosion resistance in outdoor and industrial environments\u003c\/li\u003e\n  \u003cli\u003e1.375-inch inside eye diameter and 2.5-inch outside eye diameter accommodate standard rigging hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fixed shoulder eye bolt for use with standard 5\/8-11 threaded lift points on structural steel, machinery frames, and heavy equipment bases requiring a rated vertical lift anchor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified rigger or millwright familiar with applicable ASME B30.26 rigging hardware standards. Always ensure the receiving threaded hole is clean and the shoulder seats fully and flush before applying load. Fixed eye bolts are rated for straight vertical pulls only — angular loading without a swivel or swivel hoist ring will significantly reduce rated capacity and can cause failure. Never use a damaged, bent, or visibly corroded eye bolt; remove it from service immediately.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEye Bolt Type\u003c\/strong\u003e: Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Type\u003c\/strong\u003e: With Shoulder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifting Capacity\u003c\/strong\u003e: 4,000 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEye Inside Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEye Outside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder\/Base Diameter\u003c\/strong\u003e: 0.625 inches\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: C-1035\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Hot Dipped Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.78 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SP20503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51702029713714,"sku":"SP20503","price":98.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e77f4028e5ba0bdbfe279d2332985ec_c35a0fd8-a0e1-430d-a7b4-ebe864cb2b13.jpg?v=1788408382","url":"https:\/\/voomisupply.com\/products\/gibraltar-sp20503-fixed-shoulder-eye-bolt-4000-lb-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
