Guide & full description
Complete guide: Set of 4 screws 4x5mm
A set of four M4 (4 mm diameter, 5 mm length) stainless steel spare screws, used mainly for fixing the grip vice system and other mechanical assemblies on coil tattoo machines. They are the small parts that keep the machine 'tight' within parameters — and losing one during a service is much more common than you'd think. The set is useful for any tattoo artist working with traditional machines who wants to always have spare parts in their service kit.
How to use
- Check the size of the existing screws on your machine: the set fits only in the fixing points that use M4 thread with a length of 5 mm.
- Choose the appropriate tool for the screw head — Allen key, Phillips screwdriver, or hex wrench, depending on the model.
- Remove the worn screw (or prepare the seat for the lost one), keeping the machine stable on the workbench.
- Thread the new screw by hand first to ensure the thread engages correctly — if you feel resistance from the first turns, remove it and start over, do not force it.
- Tighten firmly with the tool, then only an additional quarter turn: enough to eliminate play and prevent loosening under vibration, without overstressing the thread of the receiving component.
- Check the assembly: the grip should have no play, and the screw should not protrude beyond the material.
- Keep the remaining screws in your service kit, in a closed and labeled container, as a reserve for future interventions.
Tips from us
- Stainless steel has a tendency to gall under excessive tightening — tighten firmly, not 'to the max'; the practical rule is firm tightening plus a quarter turn.
- The vibrations of a coil machine can loosen the fixing screws over time: make it a habit to check the tightness periodically, ideally before each session.
- Do not replace with longer screws without checking the available space — the 5 mm length is calibrated for the standard thicknesses of machine construction materials.
- Keep other common sizes in your kit (on tatuat.ro you can find, for example, M3x5mm as well), to cover all the fixing points of the machine.
- If a thread seat repeatedly 'strips', the problem is with the receiving component, not the screw — do not compensate by tightening harder, check the thread of the part.
Frequently asked questions
Are these screws compatible with my machine?▾
The M4x5mm size is a common standard in the coil tattoo machine industry, used by most manufacturers especially for fixing the grip vice. The safest test: check the existing screws on your machine — if it uses M4 with a length of 5 mm, the set is compatible. If the machine uses a different size at that point, the screws are not interchangeable.
What is the difference compared to 3x5mm screws?▾
The difference is the thread diameter: M3 (3 mm) vs M4 (4 mm). M4 screws are more robust and are used in fixing points that bear higher mechanical loads, such as the grip attachment, while M3 appears on smaller components. They are not interchangeable — an M4 will not fit into an M3 seat, and an M3 will have play in an M4 seat. Check the required size before ordering.
Do they withstand sterilization and how do I sanitize them?▾
Yes, being made of stainless steel, the screws withstand both chemical disinfection and autoclaving at 134°C/2 bar, without degradation of the thread or mechanical strength. For regular use, wiping with 70% isopropyl alcohol when cleaning the machine is sufficient; autoclaving is for situations where you sterilize the assembly they are part of. The stainless steel also resists repeated contact with common studio disinfectants without corrosion.
Why are there 4 screws in the set, how many do I actually need?▾
Fixing the grip vice typically requires 1-2 M4x5mm screws, depending on the machine design. The set of 4 covers a complete service operation and leaves you with 2-3 spare pieces — useful because losing such a small screw during disassembly is extremely common. Practically, a single set provides both the current replacement and a reserve in your kit.
What tool do I need to tighten them?▾
It depends on the head type: Allen key for internal hex head, Phillips screwdriver for cross head, or a wrench for external hex head. The screws are compatible with standard service tools — just make sure the tool size is exactly the right one, because an improper tool will round the screw head and complicate later removal.
Can I use a longer screw if I don't have a 5 mm one on hand?▾
It is not recommended. The 5 mm length is calibrated for the standard thicknesses of machine construction materials: enough for the thread to engage firmly, but short enough not to protrude beyond the part. A longer screw can interfere with internal components (mechanical locking), deform the material inside, or come out the other side, creating a dangerous sharp point. Use a longer length only if you have verified that there is space.
