Save Money with KATO Tangless Inserts!

Why Tangless Inserts = Cost Savings

As technology moves forward, customer expectations and demands for higher quality fasteners is at an all time high. KATO revolutionized the industry with the introduction of the Tangless® screw thread insert, the most advanced helically coiled screw thread insert in the market today.

Tangless® CoilThread® inserts are a continuous, helically-coiled, bi-directional, wire design. This innovative design allows for installation using a drive notch located at each end of the coil insert instead of a tang located at one end of the insert.

Because KATO Tangless inserts have a notch at both ends, this eliminates the need to orient the insert during installation and saves on production cost. But that’s not all…

After installing a tanged insert you have to go back and break off the tang, this process is eliminated with Tangless inserts. In blind holes the tang must be retrieved; this process is also eliminated with Tangless inserts. Tangless inserts are FOD-Free by design, so you never have to worry about contamination by a missed tang.

What It Means for your Bottom Line

The advantages of using KATO Tangless inserts are clear: less overall installation time means lower production costs and equates to money saved. In fact, customer studies show using a KATO Tangless insert can save from $0.15 – $0.50 per hole in labor costs.

Installation isn’t the only area of cost savings. KATO Tangless inserts can save thousands of dollars by eliminating the likelihood of damage to the machined part, and preventing the need to rework or even scrap parts. Having a notch on both ends means KATO Tangless inserts can be backed up (if installed too deep), or removed without any damage to the parent material or STI threads. Try that with a tanged insert!

So, what are you still waiting for? bisco industries carries a large selection of KATO Tangless CoilThread inserts and tools. Isn’t it time YOU go tangless?

KATO Introduces the World’s Smallest Tangless CoilThread Insert

Lighter, Smaller, Stronger – KATO Inserts

Once again, KATO has redefined cutting edge in the helical coiled screw thread insert market. As technology moves forward, the expectations and demands of engineers are to design parts that are smaller, lighter, and more powerful. This holds true for everything from electronics to mechanical components. As a result, and in response to this trend, KATO continues to develop innovative new technology that pushes the envelope of wire insert manufacturing. The New 0-80 and M2 Tangless CoilThread inserts are the latest results of these efforts.

World’s smallest Tangless insert

KATO utilized state-of-the-art wire forming technology and advanced micro manufacturing techniques to produce the 0-80 and M2 Tangless CoilThread inserts, the industry’s smallest unified and metric Tangless thread sizes.

The new 0-80 and M2 Tangless CoilThread inserts are currently available in free-running 1, 1.5, and 2 diameter nominal lengths. STI taps, STI gages, installation, and non-destructive KATO removal tools for the 0-80 and M2 Tangless CoilThread inserts are also available.

With a free outside diameter as small as 0.077in and 2.5mm respectively, the KATO 0-80 and M2 Tangless CoilThread inserts are the world’s smallest unified and metric Tangless inserts!
