Battery-powered wrenches are among the most popular items we sell, so it makes sense that one of our most frequently-asked questions has to do with these torque tools:

“What is the difference between the RAD Digital D-BRAD battery torque wrench (or DB) and the RAD B-RAD battery torque wrench?”

And while their names might make them sound like interchangeable tools, there are some significant differences between these battery-powered, high-capacity torque wrenches.

In this blog post, we’ll explain the differences between and advantages of each tool.

If you want to understand the importance of proper bolting in civil engineering and bridge construction, spend some time reading about what happened to the Bay Bridge in California in 2013.

According to the Los Angeles Times, 32 bolts on the bridge snapped during tightening in March of that year, “leaving the seismic safety of the massive endeavor in question.”

These thick steel bolts connect the deck of the bridge to its “sheer keys” which control movement of the bridge during an earthquake.

America’s bridges need help.

According to an April 2019 report by the American Road and Transportation Builders Association, an estimated 47,000 bridges in the U.S. need to be repaired – if not replaced outright – to meet future traffic demands.

While this situation seems dire, the good news is that significant improvements in bridge construction and design over the past 20 years will lead to much sturdier bridges. In this blog, we’ll look at the updated standards for bolted connections in the bridge industry and the importance of calibration for bridge construction torque tools
