Advantages of KATO Tangless Inserts

Tangless inserts have the same fit, form, and function as tanged inserts but with a couple key advantages. One, tangless inserts reduce the possibility of Foreign Object Debris (FOD) from loose tangs which can cause damage to machinery. This translates into reduced costs for maintenance and repair. Two, tangless inserts are bi-directional which means that no orientation is required when installing inserts. This can speed up assembly providing additional cost savings.

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.

Inserting the Right Solution

The Challenge of Product Design Restrictions

Imagine you’re assembling an enclosure for a cell phone. You need to bind the two pieces of the enclosure together with an extremely strong yet light weight fastener. In addition you face the challenge that the pieces can only be fastened from one side of the enclosure. Engineers working with all kinds of electronic and industrial enclosures face these types of scenarios daily. So what’s the solution to a predicament like this?

The Right Solution

The answer is helical inserts (also known as CoilThread inserts, wire thread inserts, or Heli-Coil inserts). Formed from threaded coils of durable metal wire, helical inserts offer an extremely dependable and light weight fastening solution. Helical inserts’ technical specifications also allow wide variation in size, material, and plating.  Not only that, but many CoilThread inserts meet stringent military specifications that make them ideal for aircraft and defense applications.

Determining Your Specific Requirements

Perhaps you’ve determined that you need a tangless insert with a 2-56 thread size but you’re unsure what material would best suit your application. That’s when an expert comes in handy. Having partnerships with premier insert manufacturers such as Kato, bisco industries is able to provide the expertise you need. Contact a local bisco office or email our e-commerce team to get expert advice on helical inserts.
