The set of 3 original Ink Machines Allen keys, part no. 51, is intended for servicing and maintaining Dragonfly and Stingray rotary machines. The keys cover the necessary metric sizes for the M2 and M3 screws in these machines and are made from heat-treated alloy steel. It is a workshop accessory for tattoo artists who maintain their own machine — from fine adjustments to deep cleaning.
What does the kit contain?▾
The set includes 3 original Ink Machines metric Allen keys, part no. 51, in the sizes needed for the M2 and M3 screws used in the construction of the Dragonfly and Stingray machines. They are made from heat-treated alloy steel to withstand repeated tightening without losing their shape.
Which machines are these keys used on?▾
The kit is designed for Ink Machines Dragonfly and Stingray rotary machines. The keys correspond to the hexagonal heads of the M2 and M3 screws in these machines; for other models, first check if the screws use the same metric sizes before using them.
Can I use generic Allen keys from the store?▾
Technically yes, but with risks. Generic keys may have wider tolerances, and at such small sizes even a slight difference can cause the key to slip and round off the internal edges of the hex head. Inch-system keys are particularly risky because they are close in size but not identical to metric ones. If you don't use the original kit, at least choose quality metric keys that fit firmly without play.
What operations do I need these keys for?▾
They are needed for routine service operations: changing the cam and adjusting the stroke, replacing wear parts, disassembly for periodic deep cleaning, adjustments to the retention mechanism, and diagnosing mechanical issues that require access to internal components.
How do I maintain the keys and do they wear out over time?▾
Wipe them after each use and keep them dry to prevent rust and keep the set complete. Even quality keys can wear out if used frequently for firm tightening — the hexagonal corners may gradually round off. When you notice a key no longer fits firmly or slips in the screw head, replace it, because a worn key damages the screws.
Why would I buy the kit separately if I received keys with the machine?▾
As a separate part, kit no. 51 is useful for replacing lost or worn keys, or as a dedicated spare set for a second studio or each machine. Having a spare set on hand eliminates the risk of being unable to perform urgent service due to a lost or damaged key.
