Installing Standard Hex-Head Bolts

Tools required:

  1. A ½″ socket and ratchet wrench, and ½″ combination wrench.

Installation instructions:

  1. Place the sign on the square post where it meets your height requirement and line up the mounting holes with the holes on the post.
  2. Using the appropriate size bolts, insert a washer over the 5/16″ bolts and then insert the bolts into the mounting holes of the sign and through the post.
  3. Insert a washer on the other end of the bolt followed by the nut and tighten down.

Optional:

  1. Add a pair of our ribbed sign saver plates that prevents the possibility of sign dimpling during bolt tightening.
