Uxcell M4 X 20mm Nylon Thumb Screw With T-Nut – Metric Spade Handle, 2-Pack, For RC Model Aircraft, Boats, Cars, DIY Fasteners

About This Product

These uxcell nylon thumb screws are a lightweight, non-conductive fastening solution perfect for RC models and other hobby applications.

Each pack comes with two M4 x 20mm screws and matching T-nuts.

The thread diameter is M4 (metric), with a 20mm thread length and a 30mm overall length.
The rod length is also 20mm, giving you good engagement depth.

The T-nut has three pins and is 6mm high, designed to grip securely into your mounting surface.
The spade handle on the thumb screw is ergonomic and makes hand-tightening easy—no tools required for quick adjustments on the fly.

They're made from high-grade nylon, so they're corrosion-resistant, chemically stable, and provide electrical insulation, which is crucial in some electronics-heavy builds.

The injection molding is precise, so you get consistent threads and a proper fit every time.

Great for RC airplanes, cars, boats, or even light-duty household repairs where you want a firm hold without metal-on-metal contact.

A simple, handy little set for hobbyists and tinkerers.
