The set uses M12x1.75 stud threads and is sized for 14 mm T-slots, making it compatible with a wide range of standard machine tool tables. Stud lengths range from 80 mm through 200 mm, giving machinists the flexibility to clamp workpieces and fixtures of varying heights. The set includes step blocks, serrated end clamps, T-slot nuts, studs, flange nuts, coupling nuts, a holder, and a T-slot cleaner, providing a complete clamping solution in a single kit. The total assembly weight is 24 pounds.\u003c\/p\u003e\u003cp\u003eThis set is suited for production machining and toolroom environments where consistent, repeatable workholding is required. It is used by machinists and tool-and-die professionals setting up parts for milling, boring, or drilling operations. The 25 mm step block width and 22 mm T-slot nut width are matched to medium-duty machine table configurations common in job shops and manufacturing cells. The included T-slot cleaner and organized holder support efficient setup and teardown between operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e52-piece complete step block and clamp set for machine tool workholding\u003c\/li\u003e\n\u003cli\u003eM12x1.75 stud thread size for secure clamping engagement\u003c\/li\u003e\n\u003cli\u003eFits 14 mm T-slots with 22 mm T-slot nut width\u003c\/li\u003e\n\u003cli\u003eSix stud lengths included: 80 mm, 110 mm, 125 mm, 150 mm, 175 mm, and 200 mm\u003c\/li\u003e\n\u003cli\u003eIncludes T-slot cleaner and holder for organized storage and fast setup\u003c\/li\u003e\n\u003cli\u003eSet includes studs, coupling nuts, flange nuts, serrated end clamps, step blocks, and T-slot nuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with machine tool tables equipped with 14 mm T-slots, including milling machines, drill presses, and surface grinders that accept M12 stud hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard workholding practices. Always power down and lock out the machine before setting up or adjusting clamps on the table. Ensure T-slots are clean and free of chips before inserting T-slot nuts — use the included T-slot cleaner for this step. Do not exceed the load ratings of the stud hardware, and verify that clamps are properly seated and torqued before initiating a machining operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Set Type\u003c\/strong\u003e: Step Block and Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Thread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eT-Slot Size\u003c\/strong\u003e: 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Block Width\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eT-Slot Nut Width\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Lengths Included\u003c\/strong\u003e: 80 mm, 110 mm, 125 mm, 150 mm, 175 mm, 200 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents\u003c\/strong\u003e: 24 Studs, 4 Coupling Nuts, 6 Flange Nuts, 6 Serrated End Clamps, 6 Step Blocks, 6 T-Slot Nuts, 1 Holder, 1 T-Slot Cleaner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 68003G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51693059899698,"sku":"68003G","price":276.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86712441e4aafb43bfd9f31fbf65ecd3.jpg?v=1788306781","url":"https:\/\/voomisupply.com\/products\/gibraltar-68003g-step-block-clamp-set-52-pc-m12x1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
