A Drop-In anchor consists of a 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, the bottom part may be knurled. The shield also has a smooth, flangeless top that allows either flush or countersunk installation. the bottom lip of the shield is tapered to allow maximum depth and holding power.

A two-piece, internally threaded expansion anchor with four equally-spaced longitudinal slots extending from the
bottom end of the outer
shield, inside of which sits a pre-assembled dilating plug. The bottom lip of the anchor is tapered. It is permissible
for a section of the
shield to be knurled, to increase the gripping action of the anchor.
Intended for flush mounted, medium to heavy-duty applications in solid materials such as stone and concrete. It
can be used in, but are
not limited to, overhead assemblies such as duct work and pipe hangers because the internal plug holds its
position. Can also be used
to anchor handrails and floor-mounted door stops.
Anchor body: AISI 12L14 cold rolled steel
Expander Plug: AISI 12L14/1215 cold rolled steel,
Anchor body: 303 Stainless steel
Expander Plug: 303 Stainless steel
Anchors should be installed a minimum of ten anchor diameters between each other and a minimum of five anchor
diameters from the edge.
Depth of Hole
Should be at least equal to the length of the anchor.
The suggested safe working load is one-fourth the average proof test loads shown in the above table.
