Ultra-Drop™ Drop-In Anchors
USA ENGINEERED
Description
The Ultra-Drop™ Drop-in Anchor is an internally threaded,
ush mount, expansion anchor designed for use in solid
concrete, stone, and solid block based materials. The
Ultra-Drop features a knurled body that increases friction
between the anchor body and the internal walls of the hole.
Options include: standard, coil thread, lipped and mini. The
standard drop-in anchors are also available in 304SS and 316SS.
Standard and Coil Thread
Key Features & Benets
Easy to install using a hammer (or mallet) and a setting tool
Internally threaded anchor allows easy bolt removability
and service work
Two-piece anchor comprised of internally threaded anchor
body and an expansion cone insert
– Case hardened expansion cone insert prevents
galling and binding during expansion
Tapered bottom lip provides maximum depth
and holding power
Anchor design oers consistent holding power
in shallow embedment
Eliminates requirement for rod couplings
in overhead applications

Installation Information
Instructions
1. Drill the hole perpendicular to the work surface at the required
embedment depth. To assure full holding power, do not ream
the hole or allow the drill to wobble.
2. Clean the hole using compressed air and a nylon brush.
3. Place the anchor into the hole. Make sure that the top of the
anchor is ush with, or below, the level of the work surface.
4. Insert the setting tool into the threaded end of the anchor and
expand the anchor by striking the end of the setting tool with a
hammer. The anchor is set (fully expanded) when the shoulder
of the setting tool touches the anchor. Full expansion is
necessary for proper anchor performance.
5. The anchor is now ready to accept threaded hardware.
NOTE: Always wear safety glasses. Follow the drill manufacturer’s safety instructions. Use only
solid carbide-tipped drill bits meeting ANSI B212.15 diameter standards.
