Sign Bolting Sets are the economical method for mounting traffic, parking, facility and property signs. Each set contains two 5/16” diameter hex-head bolts, two nuts, and four zinc coated washers. These bolts can be used to mount signs with 3/8” mounting holes on U-Channel posts, composite posts, and square posts. 2" bolts are required for 1.12 lbs./ft. U-Channel posts and our composite fiberglass posts. 2-1/2" bolts are required for 1-3/4” square posts and 2 lbs./ft. U-channel posts with or without the addition of our sign saver plates. 3” bolts are required to mount signs on 2” square posts. A 1/2" socket and ratchet wrench and 1/2" combination wrench will be needed to install these bolts.
