Harmony Brass Nut with Cap is a 10 pack of brass nuts with a nylon cap. These were used in some older Wilderness Systems rudder kits as well as the Carolina Thigh Brace kit. They can be used to cover the sharp ends of bolts that have a 10-32 thread.
Haven't installed yet, but look good (so only 4 starts until I try them). A nice-looking, hard-to-find product. Should keep your stuff from getting torn while stowing.
Does what I needed.
