Metric Series DUO-TAPTITE® Fasteners

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.

Reduced In-Place Cost!!

DUO-TAPTITE® thread rolling screws reduce in-place fastener costs and provide vibration resistant assemblies.DUO-TAPTITE® 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 Costs

Only 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.
