Complete guide: Inkmachines nr. 45 - Retainer screw - 1pcs
The original Ink Machines retention screw (part no. 45) is the component that secures the needle bar in InkMachines rotary machines through controlled mechanical pressure instead of traditional rubber bands. It is sold individually and is a wear part: the thread, head, and tightening pressure degrade over time with each needle configuration. It is intended for tattoo artists who own an InkMachines machine and want an original replacement part with an exact fit in the retention assembly.
How to use
- Insert the needle bar into the machine and align it correctly with the cam before installing the screw.
- Screw in the retention screw manually, clockwise. Tightening is done exclusively by hand, without external tools.
- Tighten progressively and evenly until the needle bar is firmly secured on the lateral axis.
- Check the fixation: the needle bar should slide freely and smoothly on the vertical axis (needle stroke), but without any lateral play.
- Adjust the pressure according to your technique—tighter for linework where stability is needed, and more moderate for shading and blending where a bit of flexibility helps.
- Turn the machine on and listen: a uniform sound indicates correct fixation, while a clicking or abnormal vibration signals insufficient tightening—stop and adjust.
Tips from us
- Keep 2-3 spare pieces on hand so you don't get stuck mid-session if the thread fails.
- Clean the thread with isopropyl alcohol and a small brush during each deep machine cleaning to remove ink and pigment residue.
- A drop of tattoo machine maintenance oil on the thread every 2-4 weeks prevents seizing. Avoid silicone-based lubricants, which can migrate onto the needle bar.
- When ordering, verify the part number (no. 45) to ensure you receive the exact component from the retention system and not a similar part.
- Do not overtighten beyond the point where the needle bar is already secure—over-tightening prematurely wears the thread of both the screw and the machine body.
Frequently asked questions
Which machines is the retention screw no. 45 compatible with?▾
It is compatible with InkMachines Dragonfly machines (all versions, including X2) and InkMachines Stingray (all versions, including X2). The part belongs to the InkMachines retention system, designed to be interchangeable between these models. However, check the part number (no. 45) when ordering to ensure you receive the exact component needed.
What exactly is the role of part no. 45?▾
It is the retention screw that secures the needle bar in the machine through direct mechanical pressure: as you tighten it, it presses on the needle bar and locks it in axial position without restricting the vertical stroke of the needle. This system replaces traditional rubber bands and provides constant, repeatable pressure as well as easier hygiene maintenance.
How often should it be replaced?▾
It depends on how often you reconfigure the needle bar. A tattoo artist who works daily and changes needles frequently should check the screw's condition every 3-6 months. Replace it when the worn thread no longer holds the tightness, the deformed head no longer allows comfortable hand tightening, the screw loosens on its own due to vibrations, or the play on the needle bar has progressively increased.
How to tighten it correctly so there is no play on the needle?▾
Tighten exclusively by hand, without tools: align the needle bar with the cam, screw clockwise, and tighten progressively until the bar is firmly secured laterally. Final test: the needle bar should move freely vertically (stroke) but without any lateral play. When started, a uniform sound confirms correct fixation.
Can I use a generic screw instead of part no. 45?▾
It is not recommended. The original Ink Machines part is manufactured with strict tolerances—thread, diameter, length, and head geometry calibrated for InkMachines machines. A generic screw may have small dimensional differences, but enough to cause uneven tightening, damage to the machine's thread, vibrations, or premature loss of tightness. The original part protects a machine that costs significantly more.
Does it require maintenance?▾
Yes. Clean the thread with isopropyl alcohol and a small brush during each deep machine cleaning to remove ink and pigment residue. Every 2-4 weeks, apply a drop of tattoo machine maintenance oil to the thread to prevent seizing. Avoid silicone-based lubricants and visually inspect the thread and head for signs of wear.
