I have never really liked the use of eye-bolts in rocketry as most off the shelf hardware is extremely bulky with no concern for weight.
These are designed to remedy a lot of those issues.
Machined from 7075 Aluminum, they have a tensile strength comparable to steel, but at a fraction of the weight. (Only 2.33g!) They are also only 0.25" tall.
I've run these through FEA, and they look to have a max load of around 700lbs before deforming. A welded eye-bolt is 800lb for reference.
The main through hole is sized for 1/4-20 rod/nut, and the secondary mount point is for a #6-32 screw/bolt.
Since these are not a closed loop like an eye-bolt, they can be attached directly to a sewn Kevlar loop and also eliminate a quick link.
I have an initial run I would like to send out to volunteers for test flights. Shoot me a PM if you are interested.
Please keep in mind this is beta hardware, and while I have done preliminary analysis to ensure their performance, you should take additional precautions and an extra dose of common sense with their implementation.
Any other comments/questions/suggestions are welcome.
