Torque: Fact or Friction
Product Announcement from Alcoa Fastening Systems
To prove that consistent torque does not equal consistent clamp when installing fasteners, Huck engineers used a Skidmore-Wilhelm machine specifically designed to test clamp values of nuts and bolts. After testing a variety of fasteners, they found, without fail, that conventional torqued-on nuts and bolts do not deliver consistent clamp. In fact, there is as much as a 40% variance in the clamp values of the same torqued-on nut and bolt. On the other hand, the Huck BobTail® offered only a 2% variation in clamp values, from HuckBolt to HuckBolt. Using direct tension and swaging, only Huck offers consistent clamp, and a stronger joint.
