Installing Standard Hex-Head Bolts
- A ½″ socket and ratchet wrench, and ½″ combination wrench.
- 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.
- 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.
- Insert a washer on the other end of the bolt followed by the nut and tighten down.
- Add a pair of our ribbed sign saver plates that prevents the possibility of sign dimpling during bolt tightening.
