INSTALLATION INSTRUCTIONS (SOLID BASE MATERIALS)
InstallatIon InstructIons (solId base materIals)
PerMissiBle insTallaTion condiTions
Dry Concrete: cured concrete that, at the time of adhesive anchor installation, has not been exposed to water for the preceding 14 days.
Water-Saturated Concrete (wet): cured concrete that, at the time of adhesive anchor installation, has been exposed to water over
a sufficient length of time to have the maximum possible amount of absorbed water into the concrete pore structure to a depth equal to
the anchor embedment depth.
Water-Filled Holes (flooded): cured concrete that is water-saturated and where the drilled hole contains standing water at the time of
anchor installation.
hammer drIllIng
DrILLInG
1- Drill a hole into the base material with a rotary hammer drill tool to the size and embedment required by the selected steel hardware
element (reference installation specifications for threaded rod and reinforcing bar). The tolerances of the carbide drill bit must meet ANSI
Standard B212.15.
• Precaution: Use suitable eye and skin protection. Avoid inhalation of dust during drilling and/or removal.
• Note! In case of standing water in the drilled hole (flooded hole condition), all the water has to be removed from the hole (e.g. vacuum,
compressed air, etc.) prior to cleaning.
HoLE CLEAnInG (BLoW 4x, BrUSH 4x, BLoW 4x)
4X
2a- Starting from the bottom or back of the drilled anchor hole, blow the hole clean using a compressed air nozzle (min. 90 psi) or a hand
pump (supplied by Powers Fasteners) a minimum of four times (4x).
• Use a compressed air nozzle (min. 90 psi) or a hand pump (min. volume 25 fl. oz.) for anchor rod 3/8" to 3/4" diameter or reinforcing bar
(rebar) sizes #3 to #6.
• Use a compressed air nozzle (min. 90 psi) for anchor rod 7/8" to 1-1/4" diameter and rebar sizes #7 to #10. A hand pump shall not be used
with these anchor sizes.
4X
2b- Determine wire brush diameter (reference hole cleaning equipment selection table) and attach the brush with adaptor to a rotary drill tool
or battery screw gun. Brush the hole with the selected wire brush a minimum of four times (4x). A brush extension (supplied by Powers
Fasteners, Cat. #08282) should be used for holes drilled deeper than the listed brush length.
• The wire brush diameter must be checked periodically during use. The brush must be replaced if it becomes worn (less than D
min
, reference
hole cleaning equipment selection table) or does not come into contact with the sides of the drilled hole.
4X
2c- Finally, blow the hole clean again a minimum of four times (4x).
• Use a compressed air nozzle (min. 90 psi) or a hand pump (min. volume 25 fl. oz.) for anchor rod 3/8" to 3/4" diameter or reinforcing bar
(rebar) sizes #3 to #6.
• Use a compressed air nozzle (min. 90 psi) for anchor rod 7/8" to 1-1/4" diameter and rebar sizes #7 to #10. A hand pump shall not be used
with these anchor sizes.
When finished the hole should be clean and free of dust, debris, ice, grease, oil or other foreign material.

core drIllIng
DrILLInG
1- Drill a hole into the base material with a core drill tool to the size and embedment required by the selected steel hardware element (reference
installation table). The tolerances of the carbide drill bit must meet ANSI Standard B212.15.
• Precaution: Use suitable eye and skin protection. Avoid inhalation of dust during drilling and/or removal.
HoLE CLEAnInG (rInSE, BrUSH 4x, rInSE, BLoW 4x, BrUSH 4x, BLoW 4x)
RINSE
2a- Starting from the bottom or back of the drilled anchor hole, rinse/flush the hole clean with water (water line pressure) until clear water
comes out.
4X
2b- Determine brush diameter (see installation table) for drilled hole and attach the brush with adaptor to a rotary drill tool or battery screw
gun. Brush the hole with the selected wire brush a minimum of four times (4x).
• A brush extension (supplied by Powers Fasteners) must be used for holes drilled deeper than the listed brush length. The wire brush diameter
must be checked periodically during use ( f
brush
> D
min
, see hole cleaning equipment table). The brush should resist insertion into the drilled
hole, if not the brush is small and must be replaced with the proper brush diameter.
RINSE
2c- Repeat Step 2a again by rinse/flush the hole clean with water.
Following this remove all standing water completely (e.g. vacuum, compressed air, etc.) prior to further cleaning. To attain a dried borehole a
Powers compressed air nozzle is recommended.
4X
2d- Starting from the bottom or back of the drilled anchor hole, blow the hole clean (free of noticeable dust) a minimum if four times (4x).
Use a compressed air nozzle (min. 90 psi) for all sizes of anchor rod and reinforcing bar (rebar)
4X
2e- Repeat Step 2b again by brushing the hole with a wire brush a minimum of four times (4x).
4X
2f- Repeat Step 2d again by blowing the hole clean a minimum of four times (4x).
When finished the hole should be clean and free of dust, debris, ice, grease, oil or other foreign material.
