Slotted screw DIN 84 M2x3 (10pcs)

The screw that must not be missing from your toolbox

Small in size, essential in function. The DIN 84 M2x3 slotted screw is one of those references that every preparer, club driver, or modeller ends up needing sooner or later. Its standardisation under the DIN 84 norm guarantees standardised dimensions and a cylindrical head with a straight slot that fits the most common precision screwdrivers in the workshop.

Main features

• Standard: DIN 84 – cylindrical head with straight slot.
• Metric: M2.
• Length: 3 mm.
• Contents: pack of 10 units.
• Reference: CXM340.

Function and applications

The M2 metric is one of the most commonly used in the world of slot racing and precision modelling. This type of screw frequently appears in the fastening of motor mounts, guide supports, chassis covers, and numerous assemblies where space is limited and the fastening must be firm and repeatable. Having a small stock in the drawer prevents interruptions during preparation sessions or in the middle of a club competition day.

In static modelling and dioramas, they are also useful for anchoring small metal parts, structures, or accessories where an adhesive does not provide the rigidity or reversibility we need.

Assembly and usage recommendations

When working with M2 screws, it is important to use a flat-head screwdriver of the appropriate width for the slot to avoid damaging the head. Applying the correct torque —without overtightening— is particularly relevant when screwing into engineering plastics or resin chassis, where excessive force can cause cracks or deformations. If the screw will be exposed to vibrations (such as in a motor mount), a few drops of low-strength thread locker facilitate later disassembly without compromising the fastening during the race.

Frequently asked questions

What does the designation DIN 84 mean?

DIN 84 is a German standard that defines screws with a cylindrical head and straight slot. It establishes the dimensions of the head, length, and thread profile, ensuring total interchangeability between manufacturers that comply with this standard.

What screwdriver should I use with them?

You need a precision flat-head screwdriver whose width fits the M2 head slot. Watchmaker screwdrivers or the precision sets commonly found in slot workshops usually include the correct size.

Are they suitable for fastening motor mounts in slot cars?

Yes, the M2 metric is very common in this type of application. Check the thread pitch of your chassis housing beforehand to ensure it is compatible with M2 metric threads.

Can I reuse them after disassembly?

Under normal conditions, yes. If you have applied thread locker, clean them well before reassembling. Discard any screw that shows a damaged slot or crushed thread, as it may lose fastening or complicate future disassembly.

Why buy a pack of 10 units?

In slot preparation and modelling, it is common to need several screws of the same type in a single project, or simply to replenish those lost during disassembly. Having a small stock prevents unnecessary waiting when they are most needed.

The DIN 84 M2x3 slotted screw (pack of 10, ref. CXM340) is a precision metric fastener widely used in slot car preparation, static scale modelling, and diorama building. Compliant with DIN 84 standard, its cylindrical head and straight slot make it compatible with most precision screwdrivers. An essential workshop consumable for slot car racers, chassis builders, and hobbyists looking for reliable, standardised hardware at 1:32 and 1:24 scale.
