Guide & full description

Complete guide: Set of 4 screws 3x5mm

These fixing screws are among the small parts that a functional tattoo machine depends on. The set includes 4 spare pieces, with a diameter of 3 mm and a length of 5 mm, used for securing small components during assembly or service. It's exactly the kind of part that's good to always have in your maintenance kit: small, easy to lose, but essential for holding the machine together.

How to use

Turn off and disconnect the machine, then disassemble the targeted area on a clean surface — ideally a tray (preferably magnetic), to avoid losing small parts.
Compare the missing or worn screw with one from the set and confirm the fit: diameter 3 mm, length 5 mm.
Choose the correct tool for the screw head (hex/Allen key or suitable screwdriver) and use the exact size to avoid damaging the head.
Start threading by hand, a few gentle turns, to catch the thread straight and avoid cross-threading.
Tighten firmly, but without excessive force — enough to secure the component well, without forcing and damaging the thread.
Visually check that all components are securely fastened and that nothing has loosened.
Reassemble the machine and test it briefly before an actual session.
Store the remaining screws from the set in your maintenance kit as spares.

Tips from us

Always keep a spare set in your kit — a single lost screw during service can interrupt an entire session.
Work on a magnetic tray or in a small container; 3 mm parts easily jump and get lost on the floor.
Use the exact tool size for the screw head to avoid rounding the head and getting stuck with a seized screw.
For screws exposed to vibrations, you can apply a drop of medium-strength thread locker (blue variant); avoid the high-strength red variant, which makes later removal very difficult.
Periodically recheck the tightness — machine vibrations can loosen screws over time.

Warning: These are mechanical machine parts, not items that touch the client's skin, so they pose no skin hygiene issues. It is important to assemble the machine completely and correctly: ensure all screws are properly tightened before starting a session, so that no component loosens during work. Do not overtighten — forcing can damage the component's thread.

Frequently asked questions

What are the dimensions of the screws in the set?▾

Each screw has a diameter of 3 mm and a length of 5 mm. The set contains 4 identical pieces, with a total weight of approximately 6 g.

Are they compatible with my machine?▾

Check the dimensions of the existing screws on your machine before ordering. If they have a diameter of 3 mm and a length of 5 mm, and the head type matches your tools, the screws are compatible. Since assemblies vary from model to model, the safest way is to compare with an existing screw.

How many screws do I receive?▾

The set contains 4 screws of the same size (3x5 mm). This usually covers the needs of a typical service and leaves you with spare parts. If you frequently service multiple machines, it might be worth ordering more sets.

What tool do I need to install them?▾

It depends on the screw head type: for a hex/Allen head, use a hex key of the correct size; for a Phillips head, use a suitable Phillips screwdriver. Always use the exact correct size to avoid damaging the screw head.

How do I maintain and keep them clean?▾

As they are machine parts that do not touch the skin, no special skin hygiene procedure is required. Wipe off ink or disinfectant residues after service, store them in a dry, clean place, and periodically check the tightness during assembly, as vibrations can loosen them over time.

Why are the screws on the machine often lost?▾

This is common: constant vibrations can loosen the tightness over time, repeated disassembly for cleaning increases the risk of losing a part, and their small size makes them easy to misplace. That's why it's useful to always have a spare set and work on a tray during service.

Product description

The set contains 4 screws for some rotary machines. Length: 5 mm Thickness: 3 mm The 4-Piece 3x5mm Screw Set is a precision screw pack with M3 dimensions (3mm diameter) and 5mm length, designed for assembly and fastening of components on tattoo machines — both coil and rotary. These compact dimensions are frequently used at fastening points where space is limited but clamping must be firm and reliable: contact spring mounting, small component attachment to the frame, adjustment plate securing, and other precision assemblies. Manufactured from stainless steel or quality steel with protective coating, the screws offer high mechanical strength at reduced dimensions, corrosion resistance in the studio environment (humidity, disinfectant, ink exposure), and precise threading that ensures consistent tightening without premature wear of the component's internal thread. The screw head (hexagonal, Allen, or Phillips, depending on variant) allows controlled tightening with appropriate tools. The M3x5 size is a standard in modern tattoo machine miniaturization, where every gram counts for ergonomics and every millimeter influences functional geometry. The 4-piece set covers the needs of a complete service operation and provides spare parts for future replacement of lost or worn screws. Basic consumables that should always be available in the professional tattoo artist's maintenance kit. Frequently Asked Questions
