This screw features a 1\/4-28 thread size and a 1\/8 inch hex socket drive, providing secure clamping force to hold indexable inserts firmly in place during cutting operations. The overall length is 0.25 inches with a right-hand thread length of 0.53 inches and a left-hand thread length of 0.50 inches. Machinists and toolroom technicians install this hardware as part of indexable insert toolholders, boring bars, and milling bodies where precise, repeatable insert clamping is required.\u003c\/p\u003e\n\u003cp\u003eThis differential screw is suited for use in production machining environments, tool crib replenishment, and toolholder maintenance. It is compatible with clamp-style indexable toolholders that accept a 1\/4-28 differential screw with a 1\/8 inch hex socket drive. The dual opposing thread design allows a single rotation to apply significant clamping load, making insert changes faster and more consistent on the shop floor. This part is sold individually and is ordered in multiples of 10.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 thread size for precise torque and clamping engagement\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch hex socket drive for standard hex key installation\u003c\/li\u003e\n  \u003cli\u003eDifferential screw design applies high clamping load with minimal rotation\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread length of 0.53 inches and left-hand thread length of 0.50 inches\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.02 pounds for easy handling during insert changes\u003c\/li\u003e\n  \u003cli\u003eIndustry standard number LS-33 for cross-reference and replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or spare differential screw for clamp-style indexable toolholders that accept a 1\/4-28 thread differential screw with a 1\/8 inch hex socket drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians using a calibrated hex key or T-handle driver sized to 1\/8 inch. Always remove the toolholder from the machine spindle and ensure the machine is powered down and locked out before servicing insert clamping hardware. Do not overtighten, as differential screw threads can be damaged by excessive torque; follow the toolholder manufacturer torque guidance. Inspect the screw threads and seating surface for wear or damage before reinstalling an indexable insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Differential Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Socket Size\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRight-Hand Thread Length\u003c\/strong\u003e: 0.53 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeft-Hand Thread Length\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware Compatibility\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LS-33\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722297213234,"sku":"LS-33","price":69.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dfea15812099d676aa40943309301bb.jpg?v=1788588849","url":"https:\/\/voomisupply.com\/products\/value-collection-ls-33-differential-screw-1-4-28-1-8-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
