Drop-In Anchors Made in America
Published by Robert Carlisle on Mar 1st 2011
Purchase Drop-In Anchors
American made drop-in anchors can be purchased online from Concrete Fasteners The drop-in anchors are made in the United States and the steel used in their manufacturing process is melted in America. The American made certification is available with each order, and will be mailed or faxed upon request.
Applications
American made drop-in anchors can be used only in concrete. They are not designed and should not to be used in base materials such as block (CMU) or brick.
Types
American made drop-in anchors are manufactured from three different materials: zinc plated carbon steel, 304 stainless steel, and 316 stainless steel. To receive current prices on the different types of drop-in anchors, please call 216-357-7433 Monday through Friday between 8:00 AM and 5:00 PM Eastern Standard Time. The pricing on the website is listed for the imported drop-in anchor, which does not meet the Buy America Act.
Sizes
Drop-in anchors manufactured in the United States come in five diameters. The diameter of the drop-in anchor refers to the inside dimension, with threads that are national coarse threads.

Hole Diameter
The diameter of the hole that needs to be drilled into the concrete for the American made drop-in anchor is equal to the outside diameter of the anchor.

Anchor Length
Each American made drop-in anchor comes in only one length. The length of the anchor equals minimum embedment of the diameter of American made drop-in anchor.
Drill Bit
The drill bit that is used to drill a hole for the American made drop-in anchor must meet ANSI standards, have a carbide tip and be used with a hammer drill in the hammer and rotation mode. Hole size is critical, and, for the American made drop-in anchor to meet its designated holding strength, the hole must be drilled using a hammer drill. The hammer drill must be set in the hammer and rotation mode. The ANSI standard carbide bit will ensure that the tolerance requirement between hole diameter and anchor diameter are met.
Depth of Hole
Setting Tool
A setting tool is required to set the American made drop-in anchor in the concrete. Each diameter of American made drop-in anchor has a setting tool that is unique to that diameter. The setting tool is made from carbon steel and is zinc plated, with one setting tool capable of setting many anchors.

INSTALLATION VIDEO
1. Using the correct diameter carbide tipped bit that meets ANSI standards, drill hole in concrete with a hammer drill in the hammer mode for the diameter of American made drop-in anchor being installed.
2. Drill hole to a depth at least equal to the length of the American made the drop-in anchor.
3. Drop the anchor into the hole so that the top of the anchor is flush with the surface of the concrete.
4. Insert the setting tool into the threaded end of the American made drop-in anchor and strike with a hammer until the lip of the setting tool meets the lip of the anchor.
