My first exposure to tension control bolts started with getting really lucky at work. Back in the early 2000s my department relocated, and somehow I managed to get a desk with an actual window.

It can be difficult to properly fasten bolts larger than 1 in. in diameter because strength increases with the square of the diameter while the torque needed to attach them increases with the ...

Specialized bolt tensioners (Figure 2) are often used for controlled bolting during installation and maintenance checks on wind turbines, including the foundations.

Hydrocam hydraulically operated bolt tensioners are designed to overcome these problems by axially stretching bolts and studs using a pre-determined residual load to create a high integrity fixing ...

Threads on aircraft bolts (except AN-type), and most aftermarket SPS or ARP tension bolts, are of special "J" form (spec MIL-S-8879) with a larger root radius and less severe crest to minimize ...

Engineers use a “nut factor” to relate a bolt’s installation torque to the tension on it. But they need to understand the friction-related variables that contribute to the nut factor to ...

When it comes to serpentine belt tension, how your engine maintains it makes all the difference. Older engines often rely on a manual tensioner — a threaded bolt adjusted pulley that requires ...

Bolted assemblies are prone to a number of safety risks, such as incorrect assembly, which accounts for about 45% of all fatigue failures, insufficient preload, over- or under-tightening and ...
