Metric M4 Nylon Thumb Screws

This pack supplies ten M4 thumb screws with a 20 mm thread length and 30 mm overall length. The spade heads allow hand tightening without tools. They are moulded from nylon for corrosion resistance and electrical insulation. The metric threads suit standard RC airframes, cars and boats.

Spade-Head Design

The wide spade profile lets you secure propellers, battery hatches or access panels by finger pressure alone. Nylon construction avoids galvanic corrosion when fastening into aluminium or carbon-fibre parts. The non-conductive material also prevents short circuits near electronics. No driver or wrench is required for field adjustments.

Ten-Piece Capacity

Ten screws cover a typical propeller set and several airframe access points on a single model. The M4 diameter limits use to airframes tapped for that thread size; larger or finer threads will not engage. Nylon threads can strip under high torque, so they are unsuited for structural loads or vibration-critical mounts.

Questions about this item

How often should the M4 nylon thumb screws be replaced on an RC model?

Nylon thumb screws can deform or strip after repeated tightening; inspect them each flying season and replace any that show thread wear or a rounded spade head.

What is the first limit reached when the screws are used continuously on a vibrating airframe?

The M4 thread engagement of 20 mm is the limiting factor; sustained vibration can loosen the joint before the nylon yields.

Do the nylon thumb screws get hot or make noise during all‑day operation?

Nylon is an insulator and produces no audible noise; the screws remain at ambient temperature even after extended use.
