Determining the Correct
KWIK-CON II+ Fastener & Hole Depth
The Hilti KWIK-CON II+ masonry
fastening system consists of the KWIKCON II+ fastener, the KWIK-CON II+
drive tool, and a TKC or TKB matched
tolerance carbide-tipped drill bit.
onsistent performance and maximum
C
pullout strength can be assured only
when all three elements of the system
are properly used.
Fastener Length
The length of the KWIK-CON II+
fastener to be used is determined by
combining the thickness of the fixture
being attached (A) with the desired
depth of embedment in the masonry
material (B). It is recommended that a
minimum of 1" and a maximum of
1-3/4" embedment be used in
determining fastener length.
KWIK-CON II+ fasteners are available in
1/4" and 3/16" diameters. The diameter
of the fastener and the depth of
embedment affect pullout strengths.
Application strength requirements and
safety factors should be considered
when determining the depth of
embedment and fastener diameter. For
assistance, contact your local Hilti Sales
Representative.
Hole Depth
A TKC matched tolerance carbide
tipped drill bit is supplied with each box
of KWIK-CON II+ fasteners. The correct
hole depth (B+C) can normally be
obtained by drilling the full length of this
bit. In all cases, the hole must be at
least 1/2" deeper than the depth of the
fastener embedment.
Hole Diameter
The diameter of the drilled hole is also
important to the performance of the
KWIK-CON II+ masonry fastening
system. Using Hilti TKC (concrete) or
TKB (block) matched tolerance carbidetipped bits will help assure consistent
astener performance and maximum
f
pullout strength.
