Installation Tips
1.Always use a 5/32" carbide Tapcon bit — standard bits won't create proper thread engagement
2.Drill 1/4" deeper than the screw length to avoid bottoming out
3.Do not reuse holes — threads cut into concrete are damaged on removal
4.Use stainless steel Tapcons for exterior applications
