A little noisy, but function fine.

I bought two pairs of these for porch swings. Three of the four had bolts that were a little too long, preventing me from using 1/2" hardware without driving the bolt in crooked. I put 1/2" hardware on the bolt side and 3/8" hardware on the nut side. I guess I could have ground off the end of the bolt, but decided 3/8" hardware would handle the weight. Each pair has on noisy one and one quiet one, so I can always tell from inside the house that they are in use - and I have 8" thick walls...
