M2x4 Nylon Screws (x20)

Nylon screws M2x4 mm: lightweight and electrical insulation for your slot preparation

When aiming to minimise weight in a slot chassis or avoid any risk of short circuit in critical assembly areas, conventional metal screws fall short. These M2x4 nylon screws from Sloting Plus meet that need exactly: the same fastening function, without the weight or conductivity of metal.

Main features

• Material: high-strength nylon, non-conductive.
• Metric: M2 x 4 mm.
• Weight per unit: 0.025 g, practically negligible on the scale.
• Contents: bag of 20 units.
• Sloting Plus reference: SP158004.

Function and performance

Nylon offers two key advantages over steel or brass in slot applications: it does not conduct electricity and weighs significantly less. In areas where a metal fastening could create an unwanted electrical bridge —near the braids, motor mount, or electronic components— replacing it with a nylon screw eliminates the risk without compromising the fastening of plastic or resin components.

In club racing preparations, every tenth of a gram counts. At 0.025 g per screw, even using several of them in the same chassis has a minimal impact on total weight, making it easier to reach the target weight without sacrificing fastening points.

Compatibility and applications

The M2x4 mm metric is one of the most common in the slot world: it fits a multitude of plastic chassis, tuning parts, and mounts from various brands. It is frequently used to secure guides, body clips, braid supports, or small body elements. As it is a standard screw size, its compatibility is broad, although it is always advisable to check the thread pitch and depth of the housing in each specific application.

Assembly and preparation

Nylon is softer than metal, so it is advisable not to overtighten to avoid deforming the head or damaging the thread in very tight housings. It is recommended to use a screwdriver with a tip suitable for the size of the screw head and to apply only the necessary force to secure the part. In through holes or nylon nuts, the combination is particularly effective for fastenings that do not require a high torque.

Frequently asked questions

Do these screws hold as well as metal ones?

In low torque applications —which are common in slot chassis and modelling parts— nylon provides more than sufficient fastening. They are not designed for points of high mechanical stress, but for lightweight fastenings where electrical insulation or weight reduction is paramount.

How many screws come in the bag?

The bag contains 20 units of M2x4 mm nylon screws.

Are they reusable?

They can be disassembled and reassembled carefully, although nylon is more susceptible to thread wear than metal with repeated use. If the thread starts to not grip properly, it is advisable to replace the screw.

What tool is used for assembly?

A standard screwdriver of the appropriate size for the screw head. No special tool is needed, although it is recommended not to use electric screwdrivers at full power to avoid overtightening.

Can they be combined with metal nuts?

Yes, they can be used with M2 metal nuts without issue. However, if the goal is complete electrical insulation, it is most advisable to combine them with nylon nuts of the same thread pitch.
