It features a 3mm hex socket drive and an M8x1 thread, providing a reliable mechanical connection that keeps the clamp properly seated during cutting operations. This small but critical component prevents clamp movement under the vibration and cutting forces common in lathe and turning center applications. Installation requires only a standard 3mm hex key. Licensed machinists, tooling technicians, and CNC operators typically handle this hardware as part of routine insert and clamp maintenance.\u003c\/p\u003e\n\u003cp\u003eThis lock pin is used in indexable turning tool assemblies where CKM41-style clamps are specified. It is suited for both manual lathe and CNC turning center setups in production and job shop environments. Because clamp hardware is subject to wear and thread fatigue over time, keeping replacement lock pins on hand reduces downtime during insert changes. The M8x1 thread pitch is a fine-thread designation, making proper thread engagement and torque control important during installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3mm hex socket drive for standard hex key installation and removal\u003c\/li\u003e\n  \u003cli\u003eM8x1 fine thread for precise clamp engagement in indexable toolholders\u003c\/li\u003e\n  \u003cli\u003eCompatible with CKM41 clamps used on indexable turning tools\u003c\/li\u003e\n  \u003cli\u003eLightweight hardware at 0.02 pounds for easy handling and stocking\u003c\/li\u003e\n  \u003cli\u003eSold individually per package; minimum order quantity of 5 units supports shop inventory replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CKM41 clamps on indexable turning tools, as specified in the product data.

Disengage the machine and ensure the spindle is fully stopped before servicing any clamp or insert hardware. Use a calibrated torque wrench with a 3mm hex bit to achieve proper seating without over-stressing the M8x1 thread. Inspect threads on both the pin and the clamp receiver for wear or damage before reinstalling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Socket Size\u003c\/strong\u003e: 3mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp Compatibility\u003c\/strong\u003e: CKM41\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: 5\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: 31162400\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1021539\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739856732466,"sku":"1021539","price":142.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d18f41f1c017641ba56c64f16d6d35ad_d7a8660e-9a85-4b3c-8267-349517642337.jpg?v=1788819720","url":"https:\/\/voomisupply.com\/products\/kennametal-1021539-lock-pin-3mm-hex-socket-m8x1","provider":"Voomi Supply","version":"1.0","type":"link"}
