DUO-TAPTITE CORFLEX ?DUO-TAPTITE

Reduced In-Place Cost!!

TAPTITE II ? and DUO-TAPTITE ? thread rolling screws reduce in-place fastener costs and provide vibration resistant assemblies. TAPTITE II ? and 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 fasten-ing cost, have

been the benefits of using TAPTITE ? screws. TAPTITE II ? and 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. TAPTITE II ? and 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 TAPTITE II ? and 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 struc-tural 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.

Why TAPTITE II ? Over TAPTITE ?

Screws? TAPTITE II ? screws bring benefits to both fastener manufacturer and end user. TAPTITE II ? screws were designed to: - Provide a more efficient manufacturing method and tool design to result in a more consistent product.

- Be applicable to the quality and SPC

philosophies of today’s market by utilizing the capabilities of today’s state of the art tooling and fastener manufacturing equipment. - Provide more consistent torque performance, lower

thread forming torque and lower end load necessary to initiate thread forming, than

any other thread forming or thread rolling

screw including the original TAPTITE ? screw.

Behind the scenes, REMINC has provided its licensed manufacturers with a total quality system for manu-

facturing TAPTITE II ? fasteners. Included are design and processing failure mode and effects analysis pro-cedures, statistical in process control data collection

system, and improved inspection procedures and cri-teria. Although all REMINC products are designed for consistent manufacture and performance, TAPTITE II ? fasteners were physically re-designed to

meet the above quality system, to be the quality flag-ship of TRILOBULAR? products.

Note: TAPTITE II ? is often designated TYPE TT AND TT-II

“The Controllable Product ?”

Better starting stability – Axial Alignment

Less misalignment at start of driving operation . . . the self-aligning characteristic of DUO-TAPTITE ? screws reduces operator fatigue; eliminates interruptions in produc-tion; adds speed to every fastening opera-tion. Suitable for automated and robotic assembly. B – Higher prevailing torque Superior elastic action of a DUO-TAPTITE ? screw gives it better lock-ing characteristics than many fasteners specifically designed as

locking screws! Competitive round-

bodied, thread-forming fasteners have no

locking torque. Graph shows comparison of DUO-TAPTITE ? screw with IFI-124 minimum requirement for self-locking screws.

TYPICAL ANGULARITY

Lower starting end pressure

Lower starting end pressure combines with lower driving torque to reduce time and power costs right down the line. A –Higher strip-to-drive ratio The higher, more uniform, strip-to-drive torque ratio of DUO-TAPTITE

screws pro-vides a built-in safety factor against over-driving. Eliminates broken screws, dam-

aged mating threads and inferior fastenings.

Torque-tension comparison M8 x 1.25 DUO-TAPTITE ? vs.

TAPTITE ? Fastener

Superior tension at any given applied torque (with normal clamping pressure) is a major factor in the better holding capa-bility of a DUO-TAPTITE ? screw.

NOTE: All screws were tested in unthreaded weld nuts of uniform hardness (Rockwell B 82-84) hav-

ing 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 re-

corded on a BLH electronic recorder. All test data

is based on 5/16 - 18 or M8 x 1.25 screws.

Suggested hole sizes for TAPTITE II ? & DUO-TAPTITE

Screws and Bolts at various percentages of thread engagement

EXAMPLE - The shaded area

indicates that an M5 - 0.8 screw size in a 4.58 hole size provides 80% thread

engagement.

Because the above values are based on a linear relation between hole size and percentage thread engagement, the hole data becomes less accurate for engagements less than 70%.

Note also, these hole sizes are based on the U.S. basic thread depth of .6495 times the pitch and are calculated using nominal screw diameters.

Hole = D - (0.6495 x P x %), where D = nominal screw diameter.

(1) Pilot holes listed under 90% & 85% (Thread Percent) also recommended for single punch extruded holes.

See Page 11

For Pilot Hole Tolerance in terms of thread percentage, we suggest +5% to -10% of the nominal value, percent thread value.

EXAMPLE: If 80% is the percent thread for the nominal hole, the minimum hole would yield 85% thread and the

maximum hole would yield 70% thread.

自攻螺丝的扭力标准

自攻螺丝的扭力标准自攻螺丝是一种常见的紧固件，广泛应用于机械设备、家具制造、建筑工程等领域。在使用自攻螺丝时，正确的扭力标准是至关重要的。本文将就自攻螺丝的扭力标准进行详细介绍，希望能对大家有所帮助。首先，选择合适的扭力工具至关重要。通常情况下，我们会选择扭力扳手来拧紧自攻螺丝。扭力扳手是一种专门用于控制螺丝扭力的工具，能够确保螺丝拧紧的力度符合标准要求。在选择扭力扳手时，需要根据自攻螺丝的规格和材质来确定合适的扭力范围，以免因扭力过大而损坏螺丝，或者因扭力过小而导致螺丝松动。其次，了解自攻螺丝的扭力标准是非常重要的。一般来说，不同规格和材质的自攻螺丝都有相应的扭力标准。在拧紧自攻螺丝时，需要根据螺丝的规格和材质来确定合适的扭力值。通常情况下，扭力数值会根据螺丝的直径、螺距、材质等因素进行计算，以确保螺丝能够被正确地拧紧，并且能够承受相应的载荷。此外，正确的使用扭力扳手也是至关重要的。在使用扭力扳手时，需要确保扳手的调节和使用符合要求。首先，需要根据螺丝的规格和材质来调节扭力扳手的扭力数值，确保其与螺丝的扭力标准相匹配。其次，在使用扭力扳手时，需要确保施加力的方向和角度正确，以免因施加力的不当而导致扭力不准确。最后，定期检验和校准扭力扳手也是非常重要的。随着使用时间的增长，扭力扳手的精度可能会有所下降，因此需要定期对扭力扳手进行检验和校准，以确保其扭力输出的准确性和稳定性。只有保持扭力扳手的良好状态，才能确保自攻螺丝的扭力标准得到有效的控制。总之，自攻螺丝的扭力标准是确保螺丝正确拧紧的关键。正确选择扭力工具、了解扭力标准、正确使用扭力扳手以及定期检验和校准扭力扳手，都是确保自攻螺丝扭力标准的重要环节。希望大家在使用自攻螺丝时，能够严格遵守扭力标准，确保设备和构件的安全可靠。
