The body is drop forged from micro alloy steel and then quenched and tempered to deliver an optimal balance of tensile strength and ductility. The screw pin is also alloy, heat treated and tempered. A 6:1 design factor is built into the working load limit rating. Working load limit and traceability codes are permanently marked on the shackle body, supporting inspection and load accountability on the job site. Licensed riggers, ironworkers, and marine contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe mc651g is suited for residential and commercial rigging, crane picks, and below-the-hook load attachment where a galvanized finish is required to resist corrosion. The anchor shackle bow geometry accommodates multi-leg sling connections and angular loading better than a chain shackle. The screw pin design allows for quick installation and removal in applications where the shackle is not subject to rotation that could back out the pin. This shackle is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDrop forged micro alloy steel body with quenched and tempered heat treatment for maximum strength and ductility\u003c\/li\u003e\n  \u003cli\u003eAlloy screw pin, also heat treated and tempered\u003c\/li\u003e\n  \u003cli\u003e6:1 design factor built into the rated working load limit\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish for corrosion resistance in outdoor and marine environments\u003c\/li\u003e\n  \u003cli\u003ePermanent markings on body display size, working load limit, and traceability codes\u003c\/li\u003e\n  \u003cli\u003eShackle shows major deformation before failure, providing visible warning prior to any catastrophic event\u003c\/li\u003e\n  \u003cli\u003eOptional CM Smart ID RFID tracking available at time of order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw pin anchor shackle meeting dimensional requirements of federal specification RR-C-271 and exceeding its performance requirements.

Always verify the working load limit marked on the shackle body is appropriate for the intended load before use. The screw pin must be fully threaded and then backed off one quarter turn to seat correctly; never use a screw pin shackle in applications where pin rotation may occur. Inspect the shackle body, pin, and threads for deformation, cracks, or corrosion before each use and remove from service if any defects are found.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShackle Type\u003c\/strong\u003e: Anchor (Bow)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Style\u003c\/strong\u003e: Screw Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Micro alloy steel, drop forged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Treatment\u003c\/strong\u003e: Quenched and tempered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesign Factor\u003c\/strong\u003e: 6:1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: RR-C-271 (meets dimensional, exceeds performance requirements)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelling Unit\u003c\/strong\u003e: Each\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: COLUMBUS MCKINNON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mc651g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLUMBUS MCKINNON","offers":[{"title":"Default Title","offer_id":51525287510322,"sku":"MC651G","price":43.71,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/544c00dae3960426ba03a22e2f13a558.webp?v=1785469605","url":"https:\/\/voomisupply.com\/products\/columbus-mckinnon-mc651g-5-8-in-galvanized-anchor-shackle","provider":"Voomi Supply","version":"1.0","type":"link"}
