Differential screws use opposing thread directions on each end to create precise clamping force when tightened, securing indexable inserts firmly against the tool body. The LS-21 features a 10-32 thread size and a 3\/32 inch hex socket drive. Overall length is 0.87 inches, with a right-hand thread length of 0.50 inches and a left-hand thread length of 0.25 inches. This type of fastener is a standard consumable component in CNC and manual machining operations.\u003c\/p\u003e\n\u003cp\u003eThe LS-21 differential screw is used in machine shops and production environments where indexable toolholders require periodic insert changes. The clamp-compatible hardware design makes it suitable for standard indexable turning, milling, and boring tooling assemblies that rely on differential-thread clamping systems. Machinists and toolroom technicians replace these screws during routine maintenance or when thread wear reduces consistent clamping performance. Industry standard number LS-21 allows for straightforward cross-referencing with tooling catalogs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDifferential thread design generates precise clamping force on indexable inserts\u003c\/li\u003e\n  \u003cli\u003e10-32 thread size compatible with standard indexable clamp hardware\u003c\/li\u003e\n  \u003cli\u003e3\/32 inch hex socket drive for use with standard hex keys\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread length of 0.50 inches and left-hand thread length of 0.25 inches\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.87 inches for compact toolholder fitment\u003c\/li\u003e\n  \u003cli\u003eIndustry standard number LS-21 for easy catalog cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard LS-21 differential screw replacement for indexable toolholders using 10-32 thread clamp hardware with a 3\/32 inch hex socket drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or toolroom technician during insert indexing or toolholder maintenance. Disengage machine power and ensure the spindle is fully stopped before servicing any toolholder hardware. Use a properly sized 3\/32 inch hex key to seat and tighten the screw without over-torquing, which can cause thread damage in the toolholder body. Inspect the screw threads for wear or galling whenever indexable inserts are changed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\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: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.87 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRight-Hand Thread Length\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeft-Hand Thread Length\u003c\/strong\u003e: 0.25 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: 0.01 pounds\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-21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698435064114,"sku":"LS-21","price":69.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68503e4f20f4949d40e733d3d2a9ee94.jpg?v=1788362787","url":"https:\/\/voomisupply.com\/products\/value-collection-ls-21-differential-screw-10-32-3-32-hex","provider":"Voomi Supply","version":"1.0","type":"link"}
