Everyone knows that a safe is only as secure as its fastening system. Unless you have a built in wall or floor safe, consider bolting your safe into concrete to ensure that no thieves will be able to walk off with the whole safe where they can break it open at their leisure and without the pressure of being unwanted in another person’s home. This description is from ConFast—our preferred concrete fastening service provider:
Technical Information:A Drop-In anchor consists of a zinc plated steel tubular expansion shield and a solid, cone-shaped expander plug. The expander plug is case hardened and tempered to prevent galling and binding during expansion. The shield has four equally spaced slots for a portion of its length and the bottom part may be knurled. The shield also has a smooth, flangeless top that allows for either flush or countersunk installation. The bottom lip of the shield is tapered to allow maximum depth and holding power.
Drop-In concrete anchor/fastener - Installation:
- Drill a hole in the concrete using a hammer drill and a carbide tipped masonry drill bit conforming to ANSI B94, 12-77, matching the bit size with the outside diameter of the drop-in anchor being used. Make sure the hole depth exceeds the minimum embedment.
- Clear the hole of all debris.
- Drive the anchor into hole until it is flush with the surface of the concrete.
- Using the proper-sized setting tool for the anchor, expand the anchor by inserting the setting tool into the anchor and set with several solid hammer blows. The anchor is set properly when the shoulder of the setting tool is flush with the top of the anchor. To set anchor below surface:Drill the hole deeper than the anchor length. Thread the bolt into the anchor. Hammer the drop-in anchor into the hole until the bolt head is at desired depth. Remove the bolt and set the anchor with the proper-sized setting tool as described above.
