DUO-TAPTITE® Thread Rolling Screws
TAPTITE®
screws were the leap forward in high production assembly using threaded
fasteners. DUO-TAPTITE® screws represent the refinement of the
TRILOBULAR™ principle for specific demanding applications.
DUO-TAPTITE®
screws have generous lobulation at the screw point for easy entry and
optimum thread forming action plus reduced lobulation in the screw body
holding area. A stabilizing threaded dog point insures ready, aligned
entry, with easy pick-up requiring minimal starting end load.
Advantages
- High vibrational resistance
- Good axial alignment
- Low end load
- High strip-to-drive ratio
- High prevailing torque
- Good torque tension relationship
DUO-TAPTITE®
fasteners, and/or their manufacture according to REMINC specifications,
covered by one or more of the following patents: 6,089,806, 6,089,986,
6,261,040.
Note: All screws were tested in unthreaded weld
nuts of uniform hardness (Rockwell B 82-84) having 7.1mm hole
diameters. End pressure was manually developed, measured and recorded by
an electronic load cell and recorder. Drive, prevailing and strip
torque values, and torque-tension values were measured with a GSE torque
cell and recorded on a BLH electronic recorder. All test data is based
on 5/16 - 18 or M8 x 1.25 screws.

thread rolling screws are used to create strong, uniform load carrying
internal threads into untapped nut members upon installation. When
REMINC developed the original TAPTITE® TRILOBULAR™ shape thread rolling
screw, it revolutionized the use of threaded fasteners in high
production assembly. Assembly efficiency and joint performance, along
with lower in-place fastening cost, have been the benefits of using
TAPTITE® screws. DUO-TAPTITE® screws and bolts continue these benefits
along with meeting the quality and performance needs of the future.
Lower In-Place Fastening CostsOnly
15% of the total in-place cost of a fastening is the cost of the screw
or bolt. DUO-TAPTITE® screws and bolts lower the cost of the remaining
85%. The following is a list of some of the cost-savings advantages of
using DUO-TAPTITE® thread rolling screws.
- Elimination of separate tapping operations and associated costs.
- Built-in resistance to vibrational loosening eliminates the need for lock washers, adhesives, or plastic patches and plugs.
- Generates
stronger mating threads with uninterrupted grain flow due to work
hardening of the nut for higher stripping resistance.
- Accepts larger pilot hole variations than drilled and tapped holes.
- Works in punched, drilled, cored and extruded holes in many different metals.
- With
use of CORFLEX® metallurgy, can be provided in grade strengths of high
tensile bolts for use in structural applications in deep thread lengths
of engagement.
- No assembly line cross threading.
- Prevailing torque often equals or exceeds locking screw standards.
- Manufactured
to REMINC standards all over the world by over 68 of the world's
leading fastener, fastener processing and tooling companies.
