Why we like these:
There's one main feature we were looking for in a basic mil-spec castle nut: clear, deep cut staking notches.
There are a lot of castle nuts on the market with shallow stamped notched (see comparison photos). We wanted to make sure our basic castle nuts give you plenty of room to move material from the end plate into the castle nut.
