常问的问题

POWERLOK®II^TM紧固件是设计用于螺纹孔的，它们的锁紧功能可以抗振防松。当装配TAPTITE®系列紧固件时，螺栓会在光孔中攻出对配螺纹。它们也具有出色的防松性能，并且可以作为很好的接地螺栓使用。TAPTITE PRO®螺栓作为默认的接地螺栓最近被写进一家主要汽车厂标准！

绝对不会！TAPTITE® 紧固件在安装时会在未攻丝的螺母组件中形成自己的螺纹。由于不需要在螺母组件中预攻丝，因此可以降低装配总成本。

可以，TAPTITE® 螺纹形式的设计使其匹配 6H（公制）或 2B（英制）螺母组件的牙型。 尽管 TAPTITE® 紧固件设计为在装配时形成内螺母螺纹，但在某些情况下，TAPTITE® 紧固件会用于预攻丝螺母组件中。

可以，TAPTITE® 螺纹形式的设计使得 6g（公制）或 2A（英制）标准螺纹形式可以用于由 TAPTITE® 螺钉制成的螺母。

可以！被油漆或焊接飞溅物污染的孔不会妨碍 TAPTITE® 紧固件形成其内螺纹。

可以，TAPTITE® 产品会强行穿过油漆。 此外，我们的 KLEERTITE® 产品在被旋入时将刮掉油漆，以提供良好的导电性。

会推荐POWERLOK II® 紧固件用于此项应用。POWERLOK® 是我们用于螺纹孔的全金属三角牙™ 紧固件。POWERLOK® 螺钉通过结合新颖的 60° - 30° 螺纹形式和三角牙® 螺纹体，实现了增强的锁紧能力。 当螺纹形成锁紧功能时，30° 尖端会穿透螺母螺纹的牙底。 POWERLOK® 螺钉即使在没有落座前也能抵抗振动，因为锁紧功能可以贯穿紧固件的整个长度；因此，POWERLOK® 紧固件是出色的调节螺钉。

KLEERLOK® 是专为此类应用而设计的紧固件。 这是一款 POWERLOK® 紧固件，尾处添加了油漆清除功能，以便在拧入螺栓时完全刮除油漆。 POWERLOK® 螺纹提供抗振组件。

不行。不锈钢TAPTITE®紧固件太软而无法在不锈钢或钢板中自攻螺纹；它们最好用于软的、非铁素体金属如铝或镁金属。

不锈钢TAPTITE®紧固件可以轻易攻入软的、非铁素体金属如铝、镁和很多等级的纯铜或黄铜。我们建议螺栓涂蜡以防攻入时卡死。

TAPTITE® 紧固件可以重安装，但不会重攻丝。由于锥形尾引导，紧固件将找到自己的内螺纹路径。

可以，TAPTITE® 紧固件可以在螺纹孔中重复使用，并且仍然保持一定程度的抗振防松能力。

TAPTITE®紧固件有时需要比机牙螺栓稍多一点的扭矩来产生相同的夹紧力。然而，由于进行了涂蜡的后处理或涂覆了低摩擦系数的涂层，实际装配扭矩是可以降低的。

不是。由一家经认可的独立实验室进行的 扩展腐蚀 测试得出的结论是，TRILOBULAR™ 紧固件的性能并不比机器螺钉的性能受到更大不利影响。

不是。TAPTITE PRO®和TAPTITE2000®紧固件的螺杆减小了分叶使得非常接近于圆。这些产品的直径也比机牙螺栓稍大一点。因此，这些产品通常会比机牙螺栓在较高扭矩时才会断裂。

Our technical staff is always available to assist licensees and end-users in determining the root cause of an assembly problem or choosing the proper fastener design for a prospective application.

Before contacting REMINC/CONTI, please review and answer as many of the following questions as possible. Doing so will expedite the process.

• Fastener Type? (TAPTITE 2000®, TAPTITE 2000® SP™, etc.)
• Fastener Source? If distributor – who is the manufacturer?
  • We will only work on quality problems with the manufacturer involved.

• Fastener heat treat specification?
• Fastener finish (specification)?
  1. Note- obtain a print, if possible
• What is the rate of occurrence (5%, 50%, 2 screws out of 100, etc.)?
• What is the engagement depth?
  1. If it is a through hole and the point protrudes past the end of the hole
     1. engagement depth is the material thickness less any hole entry feature depth (such as a countersink or counterbore).
  2. If a blind hole
     1. engagement depth is the fastener length less the laminate thickness and less hole entry feature depth.
• What is assembly speed (rpm)? Is it a multi speed assembly?
• What is the torque setting?
• Hole type – drilled, cast, extruded, etc.?
• Hole diameter?
  1. Include top and bottom diameters if a cast, cored hole.
• Is this a new application or a long-running application?
  1. The fastener print may have an older date, but the application could be new.
  2. If an older application – has anything changed?
     1. Nut member
        1. Supplier
        2. Material type
        3. Finish or other
     2. Fastener
        1. Finish type
        2. Wax type
        3. Plating source for finish
        4. Heat treat source
  3. Is this lot specific?
     1. In other words, did switching to another lot solve the problem?

Please send us:

• A few of the “failed” screws (2-6 pieces)
• Screws from that lot for testing (at least 25 pieces, 50 is better)
• If there is a good lot, screws from that lot too. (at least 25 pieces, 50 is better)

If possible, cross sections of the application to test in. We want at least 20 holes to test in. However, if that is not possible, or quickly possible, one unused set-up will allow us to evaluate the hole.

While there are many questions here, this information is required to solve the problem and increase our response time properly.
