Whether you are maintaining a desktop FDM printer or tuning a CNC router, the locking torsion spring in your belt tensioner is the small component that keeps everything running true. This pack of 10 GT2 timing belt tensioner locking torsion springs is designed for builders and repair technicians who need a reliable stock of spares on hand.\u003c\/p\u003e\n    \u003cp\u003eEach spring is engineered to fit GT2 belt tensioner assemblies with belt widths of 6 mm to 6.5 mm (approximately 0.24 in to 0.26 in). The coil body diameter is typically 4–6 mm (0.16–0.24 in) and the wire diameter is typically 0.5–0.8 mm (0.02–0.03 in). Springs are supplied in a pack of 10, giving you enough units for multiple machines or future maintenance cycles.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include replacing worn tensioner springs on Ender 3, CR-10, Voron, and similar GT2-belt-driven 3D printers; restoring proper belt preload on CNC routers and laser engravers; and stocking a maker workshop or repair bench with GT2 tensioner spare parts for rapid turnaround.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for GT2 timing belt tensioner assemblies with 6 mm–6.5 mm belt width.
