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.

Replacing Metal with Plastic? Here’s a Solution for Weaker Threads
Maintaining Thread Strength in Plastic Parent Material
Today, manufacturers and design engineers are looking for alternative ways to decrease the cost, weight, and size of their parts. As a result, more and more companies are turning to plastic to replace heavier and more costly metal materials. Using plastic not only reduces the weight, but can also lower cost, and provide design flexibility. In fact plastic components manufactured using injection molding can be produced in a fraction of the time it takes to machine the same component from metal.
There are many pros and cons to using plastic as an alternative to metal, however one major drawback is weaker thread strength. This issue can be resolved with a product bisco industires is a franchised distributor for – KATO Tangless® CoilThread® inserts.
KATO CoilThread inserts are a helically-coiled fastener that can provide permanent, wear-resistant screw threads that exceed the strength of plastic parent materials. While made of metal, KATO CoilThread inserts weigh less and require the smallest boss diameter (minimum required material thickness around the insert) for a given size when compared to solid/brass inserts. KATO CoilThread inserts can be installed in any plastic material that can be tapped.
Bonus! Additional Cost Savings
KATO Tangless inserts have a drive notch at each end which eliminates the need for orientation thereby reducing overall installation time. In addition, KATO Tangless CoilThread inserts usually cost less than solid inserts! That means, you can reduce costs both by switching to plastic components and by securing them with KATO Tangless® CoilThread inserts. In fact, customer studies show that using KATO Tangless inserts can save from $0.15 – $0.50 per hole in labor costs.

Reduce Costs by Using Captive Screws
What is a Captive Screw?
Captive screws are designed to lock into a hole while allowing the fastened components to be detached without the complete removal of the screw. Thus a captive screw can be locked in place on a parent component without being fastened to a child component. Captive fasteners are typically locked in place using thread locking, press-fitting, or broaching.
Advantages of Using Captive Fasteners
Captive screws help control costs by minimizing damage to machinery from loose screws and by reducing the need for replacement fasteners. Captive screws also help make repairs easier by allowing easy access to components.
Captive Screw Configurations
Captive fasteners are available in a variety of configurations and designs.
Style | Locking Style | Drive Style | Materials |
Flush Captive Screws | Flare-In | Philips | Steel |
Spring-Loaded Captive Screws | Broaching / Spline | Slotted | Stainless Steel |
Low Profile Captive Screws | Thread Locking | Socket | Brass |
Knob Captive Screws | Soldering | Torx | Aluminum |
