It features a T6 Torx drive and a 2-56 inch thread, conforming to Industry Standard Number CS-120. The overall length measures 0.155 inches and the head diameter is 0.115 inches. Weighing 0.02 pounds per unit, this screw is a compact, precision fastener used by machinists and toolroom technicians to clamp indexable carbide inserts firmly in place during turning operations. Proper insert clamping directly affects tool stability, surface finish, and insert life.\u003c\/p\u003e\u003cp\u003eThis lock screw is intended for use in indexable turning toolholders that accept a CS-120 standard clamping screw. It is suited to CNC and manual lathe applications where indexable inserts must be locked securely before cutting.

Use a calibrated T6 Torx driver or key to seat and torque the screw — avoid impact tools on small-diameter insert screws. Ensure the insert pocket and screw threads are clean and free of chips before installation. Do not overtighten, as 2-56 thread screws are susceptible to shear at excessive torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorx Size\u003c\/strong\u003e: T6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.155 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 0.115 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CS-120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware Compatibility\u003c\/strong\u003e: Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00057668\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563671617842,"sku":"00057668","price":75.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61902b99cc676a2fb581d40aee3047b4.jpg?v=1786500872","url":"https:\/\/voomisupply.com\/products\/seco-00057668-lock-screw-t6-torx-2-56-thread-indexable","provider":"Voomi Supply","version":"1.0","type":"link"}
