Spikes should last forever but if your devices are placed on concrete they can lose their carbide tip. No worries! We have replacements!
Install with ¼" socket drive
Can be re-installed into existing holes.
If you need to install into a new spot a Center Punch starter hole (good), or a 1/8" drill (better) will make starting easier and reduce stress on the shank of the Stud. Your EBH device is made of tough material and doesn't act like wood - don't over-tighten or you'll twist the head of the Stud off!
