It delivers a 450 lb holding capacity through a straight-handle, horizontal actuation mechanism paired with a U-bar that allows workpiece contact across a controlled span. The flanged base provides four-point mounting for rigid fixture integration. Constructed entirely from carbon steel, the STC-HH20 is suited for production environments where repeatable, fast-cycle clamping is required. A pressure pad cap is included to protect workpiece surfaces during clamping. The overall length of 6.57 inches and height of 1.73 inches make it compact enough for close-clearance fixturing setups.\u003c\/p\u003e\n\u003cp\u003eThe STC-HH20 is used in light industrial and manufacturing settings for holding metal, wood, or composite workpieces during drilling, welding, routing, and assembly operations. The horizontal handle orientation is well suited for low-profile jigs and fixtures where vertical handle travel would interfere with tooling or adjacent clamps. The flanged base mounts directly to fixture plates, workbenches, or steel tables. This clamp is typically installed and set up by machinists, fabricators, fixture builders, or maintenance technicians working with production jigs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e450 lb holding capacity for secure workpiece retention in production cycles\u003c\/li\u003e\n  \u003cli\u003eHorizontal handle orientation with straight-handle style for low-profile fixture use\u003c\/li\u003e\n  \u003cli\u003eU-bar design with 0.98 inch clearance height under bar to accommodate varying workpiece thicknesses\u003c\/li\u003e\n  \u003cli\u003eFlanged base with four mounting holes for rigid, stable fixture mounting\u003c\/li\u003e\n  \u003cli\u003eFull carbon steel construction including handle, body, and bar for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003eIncludes pressure pad cap to protect workpiece contact surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hold-down toggle clamp for use in manual fixturing and jig applications requiring horizontal actuation and a flanged base mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or fixture builders using standard drill and fastener tooling. Power down or de-energize any associated machinery before mounting or adjusting clamp position on a fixture plate. Mounting hole diameter is 0.22 inches, so select fasteners accordingly and ensure the flanged base sits flush against the mounting surface for full holding capacity. Do not exceed the rated 450 lb holding capacity during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Capacity\u003c\/strong\u003e: 450 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Style\u003c\/strong\u003e: U-Bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Style\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.73 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Under Bar\u003c\/strong\u003e: 0.98 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Width\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar Thickness\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 0.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Distance Between Mount Holes\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Distance Between Mount Holes\u003c\/strong\u003e: 1.25 inches\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\u003eHandle Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Pressure Pad Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: BESSEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: STC-HH20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BESSEY","offers":[{"title":"Default Title","offer_id":51539558007090,"sku":"STC-HH20","price":47.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52d43f4a92f896829cb2269a3042dedb.jpg?v=1785843042","url":"https:\/\/voomisupply.com\/products\/bessey-stc-hh20-toggle-clamp-horizontal-450-lb-u-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
