Constructed from forged steel with a black oxide screw finish and zinc-plated steel spindle, it delivers 850 lb of clamping pressure across a maximum opening capacity of 1-1\/2 inches. The throat depth measures 1-1\/2 inches, providing clearance for typical workpiece thicknesses encountered in bench work and field installations. At 0.3 pounds, it is compact and easy to handle in tight spaces. HVAC, plumbing, and electrical tradespeople use this type of clamp to hold components, conduit, or sheet material firmly in place during assembly or repair.\u003c\/p\u003e\u003cp\u003eThis clamp suits residential and light commercial jobsite tasks where a reliable, small-format C-clamp is needed. It is appropriate for bench vise work, pipe fitting staging, electrical panel work, and general fabrication holddowns. The 1-1\/2-inch opening capacity makes it well-suited for clamping thinner stock, sheet metal, or smaller structural members. It is sold individually and is a standard addition to a professional tool bag or shop bench.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eForged steel body and clamp material for durability under repeated load cycles\u003c\/li\u003e\n\u003cli\u003e850 lb load capacity rated for light-duty clamping pressure\u003c\/li\u003e\n\u003cli\u003e1-1\/2-inch maximum opening capacity with 0-inch minimum for full range of thin workpieces\u003c\/li\u003e\n\u003cli\u003e1-1\/2-inch standard throat depth for adequate clearance on typical stock\u003c\/li\u003e\n\u003cli\u003eBlack oxide screw finish resists corrosion; zinc-plated spindle adds wear resistance\u003c\/li\u003e\n\u003cli\u003e5\/16-inch screw diameter provides positive grip without overtorque risk on light materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-depth C-clamp for general light-duty clamping tasks across trade and industrial applications where a 1-1\/2-inch opening capacity is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo power tools or electrical shutoff is required for clamp use. Ensure the workpiece and anvil contact points are clean and seated squarely before applying clamping pressure to prevent slippage. Do not exceed the rated 850 lb load capacity. Inspect the screw threads and swivel pad before each use and replace the clamp if threads are damaged or the spindle binds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 850 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Opening Capacity\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Opening Capacity\u003c\/strong\u003e: 0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThroat Depth Style\u003c\/strong\u003e: Standard Depth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Finish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Strength\u003c\/strong\u003e: Light-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILTON","offers":[{"title":"Default Title","offer_id":51716644667698,"sku":"21304","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cbf4cb544ffd443fff4fd8fd37864c8.jpg?v=1788529558","url":"https:\/\/voomisupply.com\/products\/wilton-21304-c-clamp-850-lb-forged-steel-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
