WHY A POWER FASTENER HOLDS

IN CONCRETE

The compression bond of the con-

crete to the power fastener accounts

for the majority of the holding power.

The power fastener displaces the con-

crete which tries to return to its original

form causing a squeezing effect.

Maximum holding power is achieved

when the depth of penetration pro-

duces a bond on the power fastener

equal to the strength of the concrete.

As a general rule, penetration should be approximately 1" to 1

into the base concrete. Make sure the concrete is at least three

times as thick as the intended power fastener penetration. NEVER

have the power fastener point protrude thru the concrete.

NOTE: Concrete needs to cure for 28 days before maximum

fastening holding power will be achieved.

WHY A POWER FASTENER HOLDS IN STEEL

Holding power in steel depends on

the elasticity of the steel. The steel

pushes back on the shank of the

power fastener.

Drop a marble into water; the water

parts, the marble continues down,

the water closes back. This is similar

to the reaction when a power fas-

tener penetrates steel.

In steel, the point of the power fastener must penetrate com-

pletely through for highest holding power. If the power fastener

does not penetrate, the spring action of the steel pushes back

on the point and tends to force the power fastener out.

Recommended applications are between 3/16-3/8" steel.

NOTE:

When fastening in steel be sure the point goes thru

the steel.
