Self-Drilling Tapping Screw for Flat Panel Signs (ST1050-Z)
PSST Hardware
Signs, sign posts, and mounting bases all need to secure to something, and Xcessories Squared has the sign-mounting hardware to do that.
Bolts and Nuts
To secure a sign post to an anchor, we offer several sizes of corner bolts and nuts. When securing a square post to a heavy wall anchor, you need a flanged shoulder bolt and nut.
Rivets
- Drive rivets - Our drive rivets are available with pre-attached nylon washers to make sure they are in place to help protect the sign panel. We have 3⁄8” and 3⁄16” drive rivets; both are available in standard sign panel colors.
- Aluminum pop rivets - We also carry aluminum pop rivets for attaching a sign panel to a cantilever sign bracket.
4-Blade Sign System
One of the strongest sign panel mounting systems is a 4-blade sign system. For that we have sign mate rivets in several sizes.
Concrete Surface Base
We have several options for securing a sign base to a concrete surface.
