Frequently Asked Questions
- Can TAPTITE 2000® screws cross-thread at assembly?
- Absolutely not, TAPTITE 2000® fasteners form
their own threads in untapped nut members as they are being installed.
This lowers the overall cost of assembly as pre-tapping the nut members
is not required.
- Can TAPTITE 2000® fasteners be used in pre-tapped
nut members?
- Yes, the TAPTITE 2000® thread form was designed
so that it would fit the envelope of a 6H (metric) or 2B (inch) nut member.
Although TAPTITE® fasteners are designed to form internal
nut threads at assembly, there are circumstances where TAPTITE® fasteners
are used in pre-tapped nut members.
- Can a machine screw be installed into a tapped hole
created by a TAPTITE 2000® fastener?
- Yes, the TAPTITE 2000® thread form
was designed so that a 6g (metric) or a 2A (inch) standard thread form
would fit within its envelope.
- Can TAPTITE 2000® fasteners be
installed into unthreaded holes that are filled with paint?
- Yes, holes contaminated by paint or weld splatter will
not prevent a TAPTITE 2000® fastener from forming
its internal threads.
- If a tapped hole is contaminated with paint and will
not allow a machine screw to be inserted, would a
TAPTITE 2000® fastener
work?
- Yes, a TAPTITE 2000® product will
force its way through the paint. Also, our KLEERTITE® product
will scrape away the paint as it is being driven to provide good electrical
conductivity.
- In a machine screw application where the screw is constantly
coming loose, what would REMINC suggest?
- POWERLOK® fasteners would be recommended
for this application. POWERLOK® is our all metal TRILOBULAR™ fastener
for use in tapped nut members. The POWERLOK® screw achieves
enhanced locking ability through the combination of a novel 60° -
30° thread form and a TRILOBULAR™ thread body. The 30° tip
penetrates the root of the nut threads as the thread form locking feature.
POWERLOK® screws resist vibration even when unseated as
the locking feature extends the entire length of the fastener; therefore
POWERLOK® fasteners make excellent adjusting screws.
- A locking screw is to be installed into a tapped hole,
but the tapped hole is contaminated with paint. What product might be
used?
- KLEERLOK® is a fastener specifically
designed for this type of application. It is a POWERLOK® fastener
with a paint-clearing feature added to the point to completely scrape
away the paint as it is driven. The POWERLOK® threads provide
a vibration resistant assembly.
- What are the enhancements made to TAPTITE 2000® that
make it a better performing fastener than the TAPTITE II® or
DUO-TAPTITE® fastener?
- TAPTITE 2000® fasteners were developed
with two goals in mind. First, was to maintain the low thread forming
torque of TAPTITE II® fasteners, and second, was to maintain
or increase the high failure torque and other structural characteristics
attained with DUO-TAPTITE® fasteners. A stabilizing point
thread feature was used to lower the end load required to start thread
forming and a unique Radius Profile™ thread form was
developed to achieve efficient torque-tension relationships. All of the
above features provide a performance level superior to any other thread
forming fastener on the market.
- What are the differences between POWERLOK® and
TAPTITE 2000® fasteners?
- POWERLOK® fasteners are designed for
use in tapped holes as a locking feature and TAPTITE 2000® fasteners
form their own threads in untapped nut members, as they are being installed.
- Can a TAPTITE 2000® fastener manufactured
from stainless steel form threads in stainless steel or steel nut members?
- No, TAPTITE 2000® fasteners manufactured
from stainless steel are not recommended for thread forming into stainless
steel or steel.
- Can a TAPTITE 2000® fastener manufactured
from stainless steel, form threads in nonferrous metals, such as copper,
brass, aluminum, etc.?
- Yes, TAPTITE 2000® fasteners manufactured
from stainless steel will thread form into nonferrous metals, such as
those listed.
- Can TAPTITE 2000® fasteners be
reinstalled or do they re-tap?
- TAPTITE 2000® fasteners can be
reinstalled and will not re-tap, as the fastener will find the internal
thread path due to the point tapered lead.
- Can TAPTITE 2000® fasteners be
used more than once in a tapped hole?
- Yes, TAPTITE 2000® fasteners can
be reused repeatedly in a tapped hole, and still retain a level of resistance
to vibrational loosening.
- Does a TAPTITE 2000® fastener require
more torque than a machine screw to be installed?
- Yes, a TAPTITE 2000® fastener requires
more torque than a machine screw due to the fact that the screw forms
its own threads in an untapped hole eliminating the need and extra cost
of pre-tapping.
- Because of the TRILOBULAR™ cross section, does
a joint assembled with a TAPTITE 2000® fastener rust
more quickly than a joint assembled with a machine screw?
- Based on testing performed by an accredited independent
lab, it was generally concluded through extensive corrosion testing that
the performance of TRILOBULAR™ fasteners was no more adversely affected
than that of machine screws.
- Does a TAPTITE 2000® fastener strip
more easily than a machine screw because the cross section of a TAPTITE 2000® fastener
is TRILOBULAR™ in shape?
- A TAPTITE 2000® fastener has reduced
lobulation on the body, is very close to round, and is slightly larger
in diameter than machine screws, and in fact have slightly greater cross
section than machine screws. Based on these facts, a TAPTITE 2000® fastener
typically strip at a higher values than a machine screw.
