Bolted joints are widely used to assemble components. That is not surprising, since they are cost effective while being relatively easy to assemble and disassemble.

Load-Indicating Fasteners for Bolted Joints

January 15, 2020

Maxbolt load-indicating fasteners can reduce downtime, premature wear, and catastrophic joint failures. An accurate and durable load-monitoring device is inserted into each fastener.

Why Threaded Fasteners Fail

Problems related to improper manufacturing, selection and installation are just as likely to cause fastener failure as hydrogen embrittlement and loosening

There are many ways to perform destructive testing. The most helpful, and preferred by manufacturers, is to intentionally destroy an assembly in a controlled environment to determine the performance capability of one or more of its components. Another way, done unintentionally and all too often by consumers, is to simply misuse a product.

Analyzing Bolted Joints for Clamp Load and Joint Stress

Bolts generate a lot of clamp load in a small area. That’s good for tight joints, but it can also create stress.

Oakland University is located a few minutes away from Chrysler’s corporate headquarters in Auburn Hills, MI. So, it’s appropriate that the school is home to the Fastening and Joining Research Institute (FAJRI), the only facility of its kind in the world.

GM Engine Assemblers Use Smart Bolts

January 2, 2014

TONAWANDA, NY—General Motors is using smart bolts equipped with RFID tags to build its new line of Gen 5 six- and eight-cylinder engines. Each bolt can store 5 kilobytes of data.

What’s With Washers?

Washers help threaded fasteners in many ways, most notably by effectively distributing and maintaining clamp load, and preventing fastener movement or corrosion.
