The set features 1-1\/2 inch step block widths, a 7\/8 inch T-slot fit, and 3\/4-10 stud thread. Stud lengths range from 3 inches through 8 inches, providing flexibility across a variety of fixture heights and workpiece thicknesses. Nut width measures 1-1\/2 inches. At 58 pounds, the set delivers substantial mass and rigidity suitable for production and toolroom environments. Machinists and setup technicians use this set to secure workpieces to machine tables quickly and repeatably.\u003c\/p\u003e\n\u003cp\u003eThis step block clamp set is suited for use in machine shops, toolrooms, and production floor environments where workholding versatility is required. The range of included stud lengths — 3, 4, 5, 6, 7, and 8 inches — allows the set to accommodate stepped and irregularly profiled workpieces without requiring additional hardware. It is appropriate for both light fixturing tasks and heavier clamping applications where positive workpiece retention is critical during cutting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50 pieces included — step blocks, clamps, studs, nuts, and washers for a complete workholding setup\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch step block width fits standard machine table T-slots via 7\/8 inch T-slot engagement\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 stud thread for reliable clamping force and compatibility with common machine table hardware\u003c\/li\u003e\n  \u003cli\u003eSix stud length options (3, 4, 5, 6, 7, and 8 inches) to match varying workpiece heights\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch nut width for positive wrench engagement during tightening\u003c\/li\u003e\n  \u003cli\u003e58-pound set weight reflects heavy-duty steel construction appropriate for machine tool environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style workholding solution for machine tables equipped with standard T-slots accepting 7\/8 inch T-slot hardware and 3\/4-10 threaded studs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or machine tool operators. Before securing workpieces, confirm the machine table is clean and T-slots are free of chips and debris that could affect seating. Tighten studs and clamp nuts with appropriate wrenches — do not use impact tools, which can overstress threads or distort step blocks. Verify clamp alignment and contact points before initiating any cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiece Count\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStep Block Width\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eT-Slot Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Thread\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Width\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Lengths\u003c\/strong\u003e: 3, 4, 5, 6, 7, and 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 58 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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20218G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51738670399794,"sku":"20218G","price":473.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c8636c60fe986e9781785a09fdea8b9.jpg?v=1788802580","url":"https:\/\/voomisupply.com\/products\/gibraltar-20218g-50-piece-step-block-clamp-set","provider":"Voomi Supply","version":"1.0","type":"link"}
