Countersunk screw DIN 963 M2x14 + lock nuts (4 pcs)

Secure fastening in every assembly: DIN 963 M2x14 countersunk screw with lock nut

When working on preparing a chassis, mounting a body or assembling parts in a static model, the small details of fastening matter as much as any other component. A screw that gives way or a nut that vibrates and loosens can ruin hours of work. This pack of 4 units of DIN 963 M2x14 countersunk screws accompanied by their corresponding lock nut meets that need exactly: a clean, flush assembly that does not loosen.

Set features

• DIN 963 standard: flat countersunk head screw with straight slot, profile that is flush with the surface once tightened, without protrusions that interfere with the fit or aesthetics of the assembly.
• M2 × 14 mm metric: diameter of 2 mm and shaft length of 14 mm, common dimensions in modelling, slot and precision small-scale assemblies.
• Lock nut included: each unit comes with its lock nut, designed to resist loosening due to vibration or repeated movement, especially useful in slot car chassis that endure continuous impacts on track.
• Pack of 4 units: practical quantity for immediate replacement or addressing multiple fastening points in the same project.

Applications in the hobby

This type of small metric screw is constantly present in the enthusiast's workshop:

• Fastening bodies and subassemblies in slot car chassis of different scales.
• Mounting and securing parts in static models where a discreet and solid fastening point is required.
• Assembling bases, pedestals or structures in dioramas and figures.
• Any workshop application where a flat head screw that does not protrude from the surface is needed.

Assembly and recommendations

As it is a countersunk screw, the receptacle in the receiving piece must be chamfered so that the head sits correctly and is flush. With the M2 metric, it is advisable to use a suitably sized flat-head screwdriver to avoid damaging the slot during tightening. The lock nut should be tightened firmly but not excessively: in plastic or resin materials, the applied force should be controlled to avoid deformation.

Storing leftover screws and nuts in a labelled screw organiser greatly facilitates work on future assemblies, where this type of metric frequently appears.

Frequently asked questions

What is the difference between a lock nut and a standard nut?

The lock nut incorporates a retention element —usually a nylon insert or a deformation in the thread itself— that generates resistance to reverse rotation. This prevents the nut from loosening due to vibrations or repeated movements, which is especially valuable in slot cars that fit and rub continuously on track.

Is it compatible with any M2 screw?

Yes. The lock nut included in this pack is of standard M2 metric and is compatible with any standard pitch M2 screw, not just those in this pack.

Is the DIN 963 countersunk screw suitable for plastics?

It can be used in plastics as long as the piece has sufficient thickness and the receptacle is properly countersunk. In very thin or fragile materials, it is advisable to consider using a washer or reinforcement at the fastening point.

What tool do I need to tighten this screw?

A flat-head screwdriver of appropriate size for the M2 screw slot. For the lock nut, a 4 mm wrench or socket is needed, although in tight spaces fine-tipped pliers can also be used.

Why does it come in a pack of 4 units?

The quantity of 4 units allows for addressing multiple fastening points in the same project or having immediate replacements without the need to manage an additional order for a single piece.

DIN 963 M2x14 countersunk slotted screws with nylon lock nuts, pack of 4 units — a precise and reliable fastening solution for slot car chassis assembly, static model kits, dioramas and any fine-scale hobby application where a flush, vibration-resistant fixing is essential. Ideal for modellers, slot car enthusiasts and collectors working at 1:32 or 1:24 scale. Reference CXM366, available at Ministry of Hobby.
