Drop-In anchors are female concrete anchors designed for anchoring into concrete. Drop the anchor into the pre-drilled hole in the concrete. Using a setting tool expands the anchor within the hole in the concrete.

Drop-in anchors require a setting tool to install. If you do not have a setting tool, be sure to purchase one.

Drop-In Anchor

USES

• Drop-In anchors should only be used in solid concrete.
• Their main use is to insert threaded rod to suspend electrical cable trays, HVAC ductwork and fire sprinkler pipe and heads.
• They can be used in applications that require a flush mounted anchor and when a bolt needs to be inserted and removed.
• A setting tool is required to set the anchor in the concrete.

INSTALLATION

• As with all female type anchors, the designated diameter of the Drop-In anchor refers to the side diameter of the anchor.
• The outside diameter of the anchor is equal to the hole diameter required to be drilled in the concrete.
• Minimum embedment for each diameter of Drop-In anchor is the length of the anchor.
• The Drop-In Anchor requires the bottom of the hole to set the anchor.
• First, drop the anchor in the hole with the threaded open end up towards the surface, then insert proper setting tool and hit with a hammer until the Drop-In anchor is fully set.

HOLDING STRENGTH

• The holding values of the Drop-In anchor are mainly dependent on the psi of the concrete and on the depth of embedment. Other factors include if steel rebar is in the concrete and on the full expansion of the Drop-In anchor.
• The Drop-In anchor has sides that are smooth to allow for more surface area to be in contact with the concrete, thereby providing consistent holding values.

SIZES

• Drop-In anchor are manufactured in five diameters, each diameter has one length.
• The Drop-In anchor is not manufactured in diameters of 7/8" or 1".
• Every size of the Drop-In anchor is available in standard zinc plating, 304 stainless steel and 316 stainless steel.
• No diameter of the Drop-In anchor comes in a galvanized carbon steel.
