It delivers a 7,500 lb (33,361.7 N) load capacity through a round, internally threaded plunger with a 1\/2-13 thread size and 4 inches of plunger travel. The flanged base with six mounting holes provides a rigid, stable platform for permanent fixture mounting. Constructed from carbon steel throughout, the 640 is built to handle repeated clamping cycles in demanding shop environments. A straight red handle gives the operator a clear grip and visual reference during operation.\u003c\/p\u003e\u003cp\u003eThis clamp is suited for production welding fixtures, machining jigs, and assembly stations where a high-capacity straight line clamping action is required. The flanged base design makes it appropriate for bench-top or plate-mounted fixture work in both light manufacturing and heavy fabrication settings. The internal plunger thread accommodates standard tip attachments for workpiece contact customization.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7,500 lb (33,361.7 N) load capacity for heavy-duty workholding\u003c\/li\u003e\n\u003cli\u003e4 inches of plunger travel with 1\/2-13 internal thread for tip compatibility\u003c\/li\u003e\n\u003cli\u003eFlanged base with six mounting holes for secure, permanent fixture installation\u003c\/li\u003e\n\u003cli\u003eRound plunger, 0.87 inches in diameter, with 1.25 inches centerline height\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction for durability in weld and fabrication environments\u003c\/li\u003e\n\u003cli\u003eStraight red handle for clear operator visibility and positive actuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style straight line action clamp suitable for industrial workholding fixtures requiring a flanged-base, six-hole mounting pattern and 1\/2-13 internal plunger thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by fixture builders or tooling technicians using standard fasteners through the six flanged mounting holes. Ensure the mounting surface is flat and rigid to prevent clamp deflection under load. Confirm all fasteners are fully torqued before applying clamping force. Disconnect or de-energize any associated pneumatic or hydraulic circuits before servicing or repositioning the clamp in automated fixture applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacity\u003c\/strong\u003e: 7,500 lb (33,361.7 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Travel\u003c\/strong\u003e: 4 inches (101.6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Thread Style\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Thread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.87 inches (22.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Centerline Height\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.65 inches (321.31 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 4.28 inches (108.71 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 8.53 inches (216.66 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Width\u003c\/strong\u003e: 3.0 inches (76.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Distance Between Mount Holes\u003c\/strong\u003e: 3.56 inches (90.42 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Distance Between Mount Holes\u003c\/strong\u003e: 2.13 inches (54.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 0.41 inches (10.41 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Mounting Holes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Style\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Straight\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\u003eWeight\u003c\/strong\u003e: 6.71 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112100\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: 640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DE-STA-CO","offers":[{"title":"Default Title","offer_id":52060393734450,"sku":"640","price":182.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b740d6c865b6cf32e9dcabed39349353.jpg?v=1790041051","url":"https:\/\/voomisupply.com\/products\/de-sta-co-640-straight-line-action-clamp-7500-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
