Built from carbon steel with a zinc finish coating, it delivers a holding capacity of 375 pounds (1,670 N) through a straight, red-handled actuator that travels 60 degrees to lock. The U-bar design with a fixed spindle provides a clear, adjustable hold-down point, while the flanged base allows secure four-point mounting to fixtures, jigs, and workholding surfaces. Licensed machinists, toolmakers, and production technicians are the primary installers of this clamp.\u003c\/p\u003e\n\u003cp\u003eThe 317-U is suited for light-to-medium duty clamping in machine shop fixtures, welding jigs, assembly stations, and quality inspection setups. The 185-degree bar opening gives operators wide clearance for part loading and unloading without obstruction. The flanged base mounts to flat surfaces using four holes spaced 0.63 inches (length) by 1 inch (width) on center, making it compatible with standard fixture plate layouts. The package includes two flanged washers, two nuts, and the spindle for a complete ready-to-mount assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e375 lb (1,670 N) holding capacity for reliable workpiece retention\u003c\/li\u003e\n  \u003cli\u003e60-degree handle travel for fast, low-effort locking and release\u003c\/li\u003e\n  \u003cli\u003e185-degree U-bar opening for wide part clearance during load and unload\u003c\/li\u003e\n  \u003cli\u003eFixed spindle with 5\/16-18 thread and 1.97 inches of spindle travel for clamping height adjustment\u003c\/li\u003e\n  \u003cli\u003eFour-hole flanged base for rigid, vibration-resistant fixture mounting\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction with zinc finish coating for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003eIncludes flanged washers, nuts, and spindle  -  no separate hardware required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit addition for standard vertical hold-down toggle clamp applications requiring a flanged base and U-bar configuration with a 375 lb holding capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using four mounting screws through the flanged base holes, sized to the 0.27-inch mounting hole diameter; verify the base is fully flush and fasteners are torqued evenly before applying clamping loads. Adjust the fixed spindle to the required clamping height using the 5\/16-18 threaded spindle prior to final mounting. Confirm the clamp locks fully over-center before putting the fixture into production  -  a clamp that does not reach its over-center position will not hold rated capacity. Follow applicable workplace safety and machinery guarding standards when integrating toggle clamps into automated or semi-automated fixtures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Capacity\u003c\/strong\u003e: 375 lb (1,670 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Orientation\u003c\/strong\u003e: Vertical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Movement\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Opening\u003c\/strong\u003e: 185 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Style\u003c\/strong\u003e: U-Bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar End Type\u003c\/strong\u003e: Fixed Spindle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Thread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Travel\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Style\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Mounting Holes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 0.27 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Distance Between Mount Holes\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Distance Between Mount Holes\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Under Bar\u003c\/strong\u003e: 2.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 5.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront of Base to Toggle Bar Tip\u003c\/strong\u003e: 2.53 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Width\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 2 Flanged Washers, 2 Nuts, Spindle\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: DE-STA-CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 317-U\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DE-STA-CO","offers":[{"title":"Default Title","offer_id":52120390959410,"sku":"317-U","price":46.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/426a3ffaee5b7895693414b7576a00aa.jpg?v=1790083727","url":"https:\/\/voomisupply.com\/products\/de-sta-co-317-u-hold-down-toggle-clamp-375-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
