Tension indicating bolts
http://www.smartbolts.com/smartbolt-dti/ Web5 Jun 2024 · A tension control bolt is a pre-assembled bolt, nut, and washer used especially in steel frame construction. Also known as a TC bolt, they possess a domed head rather than a hex head because they are installed from a spline on their other end. This spline connects with a special power wrench for installation.

Starting from the bottom of the unit, the basic parts of a hydraulic tensioner are: Nut: This sits on the flange, while the bridge sits around the nut. As you can see, the bolt protrudes through the nut, and you need to make sure that you have one diameter of that stud sticking above the nut. Load cell: This sits ...
Web5 Sep 2024 · Torque is a method of creating tension in the bolt by stretching it. To visualize the rotational force causing stretch in the bolt, consider that the bolt’s threads act as a wedge or an inclined plane wrapped around the bolt’s body. As torque is applied to the bolt and the bolt rotates relative to the nut or to a threaded hole, the wedging ... Web15 Apr 2008 · An unloaded HR SmartBolt displays a bright yellow indication, which will remain yellow until the bolt has been tightened to about 90% of the design tension. At that point it begins to become slightly green. At 100% design tension, the indication is a "grass green". Should the bolt be over tightened, the indicator color will darken to nearly black.
