Sold as an individual part, not a set of two nuts.
The easiest way to secure a forward 1010 rail button when a centering ring isn't an option. These Rail Button Nuts conform to the diameter of the specified airframe, and include a tapered side (which faces aft) to reduce the chance of snagging the recovery train on deployment. The Rail Button Nut arrived preassembled with the 8-32 T-nut securely in place. Simply drill a hole in the airframe, and install the railbutton and rail button nut.
Fits popular airframe sizes from 38mm to 6 in diameter.
No airframe, rail button or screw included.
Conformal Rail Button Nuts (8-32, ea)
Printed from a professional grade PETG plastic with a high Tg (Glass transition) of 76 deg C (169 deg F), so it will hold up to the most extreme flying site conditions. All parts are solid (100% infill), so no internal voids or honeycombs.
