It's a nut. Works great.
Solid hardware. The website said that each nut purchased gets you 5 minutes of advice, so answer your email MG.
GREAT FIT... LOVE 'EM
perfectly fit for GL and all the braces. Might will secure the brace from making once it is tightened.
Not always in HD or Lowe's. Highly recommended to get it here for a perfectly fit.
