2.0 USES

The Hilti KH-EZ, KH-EZ SS316, KH-EZ P, KH-EZ PM,

KH-EZ PL, KH-EZ C, KH-EZ C SS316, KH-EZ E, KH-EZ I

and KH-EZ CRC screw anchors are used as anchorage in

cracked and uncracked normal-weight and lightweight

concrete having a specified strength, f′

of 2,500 psi to

8,500 psi (17.2 MPa to 58.6 MPa); and cracked and

uncracked normal-weight or sand-lightweight concrete over

steel deck having a minimum specified compressive strength,

f′

, of 3,000 psi (20.7 MPa) to resist static, wind and seismic

(Seismic Design Categories A through F) tension and shear

loads.

The Hilti KH-EZ, KH-EZ SS316, KH-EZ P, KH-EZ PM, KH-

EZ PL, KH-EZ C, KH-EZ C SS316, KH-EZ E, KH-EZ I and

KH-EZ CRC screw anchors are an alternative to anchors

described in Section 1901.3 of the 2021, 2018 and 2015 IBC

and Sections 1908 and 1909 of the 2012 IBC. The anchors

may also be used where an engineered design is submitted

in accordance with Section R301.1.3 of the IRC.

3.0 DESCRIPTION

3.1 KH-EZ:

The KH-EZ anchors are comprised of a body with hex washer

head. The anchor is manufactured from carbon steel and is

heat-treated. It has a minimum 0.0003-inch-thick (8 μm) zinc

coating in accordance with DIN EN ISO 4042. The anchoring

system is available in a variety of lengths with nominal

diameters of

-inch,

-inch and

-inch.

The KH-EZ is illustrated in Figure 2.

The hex head is larger than the diameter of the anchor and

is formed with serrations on the underside. The anchor body

is formed with threads running most of the length of the

anchor body. The anchor is installed in a predrilled hole with

a powered impact wrench or torque wrench. The anchor

threads cut into the concrete on the sides of the hole and

interlock with the base material during installation.

3.2 KH-EZ I:

The KH-EZ I anchors are comprised of a body with a long

internally threaded (

-inch,

-inch, or

-inch internal

thread) hex washer head. The anchor is manufactured from

carbon steel and is heat-treated. It has a minimum

0.0003-inch-thick (8 μm) zinc coating in accordance with DIN

EN ISO 4042. The KH-EZ I is illustrated in Figure 3.

The over-sized hex head is larger than the diameter of the

anchor and is formed with serrations on the underside. The

anchor body is formed with threads running most of the

length of the anchor body. The anchor is installed in a

predrilled hole with a powered impact wrench or torque

wrench directly to the supporting member surface. The

anchor threads cut into the concrete on the sides of the hole

and interlock with the base material during installation.

Shear design values in this report for the KH-EZ I are for

threaded inserts with F

equal to or greater than 125 ksi. For

use with inserts with F

less than 125 ksi, the shear values

are multiplied by the ratio of F

of insert and 125 ksi.

3.3 KH-EZ P, KH-EZ PM and KH-EZ PL:

The KH-EZ P, KH-EZ PM and KH-EZ PL anchors are

comprised of a body with round pan style head with an

indented area in the top of the head with a six point star

configuration. The KH-EZ P, KH-EZ PM and KH-EZ PL have

different size pan style heads: small (P), medium (PM) and

Large (PL). The anchor is manufactured from carbon steel

and is heat-treated. It has a minimum 0.0003-inch-thick

(8 μm) zinc coating in accordance with DIN EN ISO 4042.

The KH-EZ P, KH-EZ PM and KH-EZ PL are available in

-inch diameter. The KH-EZ P, KH-EZ PM and KH-EZ PL

are illustrated in Figure 4.

When drilling dust is not removed after hole drilling, make sure to drill deep enough to achieve hnom, taking into account the depth of debris remaining in the hole. If dust and debris is removed from the drilled hole with the Hilti TE-YD or TE-CD Hollow Drill Bits or compressed air, vacuum, or a manual pump, hnom is achieved at the specified value of h0.
