The main thread serves to position the tensioner on the bolt or stud against the hardened washer and the load bearing surface. 3 With Superbolt® tensioners you have chosen a technologically superior product. The National Weather Service later identified the culprit as a “superbolt,” which created what some referred to as a “thunderquake” strong enough to set off car alarms within a half-mile radius of the location of the strike. The loads are transfered through the nut body which is positioned on the main thread by hand. Jackbolts have a small friction diameter and can therefore create a high thrust force with relatively little torque input. Combining satellite data with ground-based measurements, the researchers also found that superbolts are indeed a different kind of lightning. 2 Superbolt®, Inc. • www.superbolt.com ... an equally strong reaction force in the main bolt head. The ﬁrst measurement of a superbolt was made by the optical payload on the your username. SUPERBOLT® ® By turning the jackbolts, a strong thrust force is generated. Jackbolts have a small friction diameter creating a high thrust force for relatively little torque. your password It is purely mechanical and, therefore, very safe. The thrust force from the jackbolt creates an equally strong reaction force in the main bolt head. The following simple steps will help you with your application. Peterson’s work describes ordinary superbolts as “ubiquitous,” and notes that they can occur with just about any strong thunderstorm in North or South America. Welcome! This thrust force is directed against a hardened washer. "One lightning stroke even exceeded 3 terawatts of power – thousands of times stronger than ordinary lightning detected from space," Peterson said. Superbolt tensioners are designed as direct replacements for conventional nuts and bolts. Introduction The most energetic lightning emissions have been termed “superbolts,” outshining normal lightning by a factor of 100 or greater. 2) The loads are transferred through the nut body which is positioned on the main thread by hand. High compressive strength jackbolts have a small friction diameter creating a high thrust force with relatively little torque. The thrust force of many jackbolts and the opposite reaction force of the main bolt head create a strong clamping force on the flange. One eyewitness told local news media that their bed was shifted 4 feet due to the shaking associated with the bolt. Log into your account. These devices can be threaded onto a new or existing bolt, stud, threaded rod or shaft. (>350 GW), however, predominantly come from strong +CGs and may still merit the “superbolt” distinction. How Superbolt tensioners work: 1) By tightening the jackbolts, a strong thrust (axial) force is generated. reaction force of the main bolt head create a strong clamping force on the flange. This thrust force is directed against a hardened washer. 1. Why Superbolt ® Tensioners?
