It delivers a 150 lb (665 N) holding capacity through a U-bar with a fixed spindle end. The clamp body and handle are constructed from carbon steel with a zinc finish coating, providing corrosion resistance in light industrial environments. The T-handle features a red grip for quick identification and confident actuation. With a 170-degree handle movement arc and a 90-degree bar opening, the 305-U locks and releases workpieces quickly during repetitive production cycles. Machinists, toolmakers, and fixture builders are the primary installers of this clamp.\u003c\/p\u003e\u003cp\u003eThe 305-U is suited for use in light-duty workholding applications on machining centers, welding fixtures, assembly lines, and inspection stations. Its flanged base with four mounting holes simplifies direct bolting to flat fixture plates or benchtop tooling. The compact overall footprint, measuring 2.21 inches in length and 1.43 inches in height, makes it practical in tight fixture layouts where multiple clamps are positioned close together. The M5x0.8 threaded spindle allows fine height adjustment to accommodate workpiece thickness variation, with 0.5 inches of spindle travel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e150 lb (665 N) holding capacity for light-duty workholding applications\u003c\/li\u003e\n\u003cli\u003eHorizontal T-handle with 170-degree movement arc for fast lock and release\u003c\/li\u003e\n\u003cli\u003eU-bar with fixed spindle and M5x0.8 thread, providing 0.5 inches of spindle travel\u003c\/li\u003e\n\u003cli\u003eFlanged base with four mounting holes for direct fixture plate installation\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction with zinc finish coating for durability\u003c\/li\u003e\n\u003cli\u003eIncludes one spindle, two nuts, and two washers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hold-down toggle clamp for use in standard fixture and jig tooling applications requiring a horizontal, flanged-base U-bar clamp with an M5x0.8 spindle thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by toolmakers or fixture engineers using standard hand tools. Mount the flanged base to a flat, rigid surface using four fasteners through the 0.18-inch diameter mounting holes before placing the clamp into service. Verify spindle height adjustment is locked with the provided nuts before applying clamping load. Inspect the toggle linkage and spindle threads periodically for wear when used in high-cycle production environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Capacity\u003c\/strong\u003e: 150 lb (665 N)\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: T-Handle\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\u003eBar Opening\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Movement\u003c\/strong\u003e: 170 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Thread Size\u003c\/strong\u003e: M5x0.8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Travel\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight Under Bar\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront of Base to Toggle Bar Tip\u003c\/strong\u003e: 1.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBar Width\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Mount Holes (Length)\u003c\/strong\u003e: 0.53 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Mount Holes (Width)\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Mounting Holes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eHandle Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Style\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 1 Spindle, 2 Nuts, 2 Washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162902\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 305-U\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DE-STA-CO","offers":[{"title":"Default Title","offer_id":51972026171698,"sku":"305-U","price":24.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd3487f41501ad98e7d2d5e3c40b433c.jpg?v=1789961364","url":"https:\/\/voomisupply.com\/products\/de-sta-co-305-u-toggle-clamp-150-lb-u-bar-flanged-base","provider":"Voomi Supply","version":"1.0","type":"link"}
