It uses a T20 Torx drive and a 10-32 thread, providing reliable clamping force to keep carbide or cermet inserts seated during machining operations. The overall length is 0.75 inches and the head diameter measures 0.35 inches. Installed by machinists and toolroom technicians, this screw is a direct consumable in high-cycle CNC and manual turning, milling, and boring setups where insert retention is critical to dimensional accuracy and tool life.\u003c\/p\u003e\u003cp\u003eThis lock screw is suited for use in production machining environments where indexable tooling systems are standard. It is compatible with insert holders designed around an inscribed circle size of 0.625 inches. Typical applications include turning centers, vertical and horizontal machining centers, and boring bars that accept indexed insert pockets requiring a 10-32 threaded retention screw with a T20 Torx interface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eT20 Torx drive for positive engagement and reduced cam-out risk during tightening\u003c\/li\u003e\n\u003cli\u003e10-32 thread size for use in standard indexable insert pocket threaded bores\u003c\/li\u003e\n\u003cli\u003e0.75 inch overall length suits typical insert pocket depths in production toolholders\u003c\/li\u003e\n\u003cli\u003e0.35 inch head diameter provides broad clamping contact across the insert face\u003c\/li\u003e\n\u003cli\u003eCompatible with inserts having a 0.625 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds — minimal impact on toolholder balance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or spare lock screw for indexable insert toolholders requiring a 10-32 threaded Torx-drive retention screw with a T20 drive size and an insert inscribed circle of 0.625 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLock screw installation and replacement should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine before accessing the toolholder pocket. Use a calibrated T20 Torx key or driver to seat the screw — do not use impact drivers or substitute drive sizes, as this can damage the screw head or strip the threaded bore. Inspect the threaded bore in the toolholder for wear or contamination before installing a new screw.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Lock Screw for Indexables\u003c\/li\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: Torx\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorx Size\u003c\/strong\u003e: T20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 0.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware Compatibility\u003c\/strong\u003e: Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TGS-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706792902962,"sku":"TGS-3","price":26.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e308c35fcaa0f3a7214685e0cf61a6e.jpg?v=1788436649","url":"https:\/\/voomisupply.com\/products\/value-collection-tgs-3-indexable-insert-lock-screw-t20","provider":"Voomi Supply","version":"1.0","type":"link"}
