Anchor bolts are mechanical
fasteners that attach and secure
objects to concrete surfaces.
One end of the anchor bolt is
installed into the concrete and
the other end is visible above
the concrete. The end that is
exposed is typically threaded for
attaching equipment.

Anchor bolts are designed to make your
life easier by securing structures in place.
This includes structural and
nonstructural equipment. These versatile
bolts are used in many industries.
Common applications include:
•Chemical, petrochemical, and oil & gas
equipment supports
•Power and steel industry
•Construction industry
•Rail and aviation infrastructure
•Pharmaceutical and food processing plants

6. Types of
Anchor Bolts
Anchor bolts are
categorized into
two types:

Cast-in-place anchor
bolts: Set into wet
concrete and cured
in place. Common
examples include L
bolts and J bolts.

7. Drop-in anchor
bolts: Installed
into pre-cured
concrete using
a drilled pilot
hole. Common
examples
include wedge
anchors and
sleeve anchors

8. 1. Wedge Anchor
Bolts
Wedge anchors are
widely used for their
strength, corrosion
resistance, and ease of
installation. They
expand against the
concrete when
tightened, making
them ideal for heavy
loads and shear force
applications. Available
in zinc, galvanized,
and stainless steel

9. 2. Drop-in Anchor
Bolts
Drop-in anchors are
female-style
anchors that are
placed into pre-
drilled holes and set
with a setting tool.
Ideal for use with
threaded rod to
suspend equipment
such as ductwork,
cable trays, and fire
sprinkler heads.

10. Bolts
L bolts and J bolts
are bent-bar
anchor bolts set
into wet concrete.
Commonly used
afor structural
applications such as
signposts, shafts,
heavy hardware,
and tooling. They’re
designed to be
used with
compatible nuts
and washers

11. Bolts
Sleeve anchors
consist of a
threaded bolt with
an expander sleeve.
When the nut is
tightened, the
sleeve expands to
grip the concrete.
Available in a variety
of sizes and head
styles, perfect for
versatile fastening
applications.

12. 5. Strike Anchor
Bolts
Strike anchors
(hammer drive
anchors) are
impact-set fasteners
ideal for lightweight
fixtures. Insert into
pre-drilled holes
and strike the pin to
expand the anchor.
Not typically
removable once
installed.

13. 6. Split Drive
Anchor Bolts
Split drive anchors
feature a split base
that expands as it is
driven into
concrete. Ideal for
light-duty
applications in
concrete, brick, or
block

14. Anchors
Lag shield anchors
are female anchors
with ribbed sleeves
and used in
conjunction with
lag bolts. Insert into
pre-drilled holes
and expand by
threading in a lag
screw. Ideal where
vibration or
movement could
affect the
connection.

15. Which Anchor
Bolt is Right
for You?

To select the proper anchor bolt, consider the
following factors:
Hole diameter (larger holes = greater load
capacity)
Embedment depth (deeper = stronger)
Base material of the fixture
Environmental exposure (e.g., moisture,
corrosion risk)
Load type (shear, tension, vibration)
Concrete strength and type
Spacing and edge distance requirements
