M4 x 45mm Nylon Thumb Screws for RC Models

These M4 nylon thumb screws measure 45mm in thread length and 55mm overall. The pack contains ten pieces designed as fastener hardware for radio-controlled airplanes, cars, and boats. The spade head allows hand-driven installation without tools.

Hand-Tightened Nylon Limits Torque

The plastic construction prevents the high clamping force achievable with metal screws and may strip under excessive tightening. Nylon softens at elevated temperatures, so these fasteners are unsuitable for engine mounts or high-friction areas. The M4 metric thread fits only matching tapped holes or nuts.

Replaces Lost or Stripped Metal Hardware

Switching to these screws reduces weight and eliminates corrosion on canopy latches, battery straps, or wing bolts. The change is worthwhile when frequent field removal is needed and the joint sees vibration rather than structural load. They do not suit high-stress airframe connections requiring metal strength.
