Bolted Joint Methods: Direct Tension Control

06/05/2018 11:01 AM

In our last blog post we discussed some common indirect bolted joint tensioning methods, including torque control, torque and turn control, and stretch control. Some of these methods offer more precision than others, although none offer direct control over the tension created in the fastener the way the following methods

Bolted Joint Design: The Difference Between Tension, Shear and Bending Joints

04/25/2018 11:25 AM

There are several different ways loads can be applied to bolted joints, each of them leading to specific effects on that joint that are the result of how the joint is loaded and responds to the load. Common load types include tension, shear and bending joints, each of which gets its name from the type […]

Mechanical Properties of Steel Bolts

04/10/2018 06:05 AM

Bolted joint applications are designed to support or transmit some form of externally applied load. When selecting materials, it’s vital to choose according to the mechanical properties of steel bolts. Out of all these properties, tensile strength is perhaps most commonly associated with standard fasteners. This is the greatest tension applied load a fastener can […]

The Importance of RAD Smart Socket Calibration

03/20/2018 09:00 AM

If you purchased a RAD smart socket in the last few years, this is a good time to make sure its calibration is up to date. Most experts in the torque tool field would recommend having smart socket calibration performed annually, but this time frame can depend on customer usage and their quality processes.

The Importance of Torque Transducer Calibration

02/27/2018 11:15 AM

Torque transducers are testing and verification instruments that check the accuracy of torque wrenches. Manufacturers, construction crews and service companies use transducers to perform spot checks on their torque wrenches. These checks, coupled with yearly torque wrench calibration, can give customers assurance that torque equipment meets expectations.

The Wind Tech’s Guide to Bolted Joints

02/06/2018 10:30 AM

Nearly every part of a wind turbine is fastened together with bolted joints. And these bolts are, in a sense, under constant threat from vibration, fatigue, bolt relaxation and corrosion. This is an issue we’ve discussed before on this blog, but one that’s important enough to revisit. Here are some ways to protect the countless […]
