Our improved kit includes two extra bolts. The longer 2.5” bolts are used for heavy-weight 2-pound posts. The shorter 1.5” bolts are used for the medium-weight 1.12-pound posts. Use the bolts that fits your post and recycle the other pair.
- DURABLE ZINC-PLATED STEEL: Bolts, nuts, and washers are made from zinc-plated steel that resists rust and won't break down outdoors.
- DUAL BOLT LENGTHS: Kit includes both 2.5" and 1.5" bolts for heavy-duty and standard u-channel posts; use the right pair and recycle the rest.
- UNIVERSAL FIT: 5/16" bolts match the 3/8" pre-drilled holes on our aluminum signs and work with u-channel, square, and round posts.
- ONE KIT, TWO POST WEIGHTS: Works for both 2 lb heavy-weight and 1.12 lb medium-weight u-channel posts, so you only need to stock a single kit.
- PACK CONTENTS: One kit with 4 zinc-plated steel bolts (two 5/16" x 2.5", two 5/16" x 1.5"), 2 nuts, 2 lock washers, and 2 nylon washers.

These were very helpful in securing the sign. It was helpful to have everything in one place. The kit included a plastic washer and a lock washer. There was one problem, the diameter of the bolt was larger than the standard hole that is in common U-shaped steel posts in the US. I had to drill the hole a little larger.
