A new wood screw from?Germany’s Schrauben GmbH & Co KG won top honors in the Fastening Technology Innovation Forum at the 2010 International Hardware Fair in Cologne, Germany.
Wire reports said that a panel of media and industry experts chose the newly launched Heco Unix screw, a full-thread wood screw that, through a reduction in thread pitch from tip to head, is designed to ensure tighter contact between two wood elements. “Unlike a partial thread screw normally used to ensure this clamping action, the Heco Unix screw maintains continued thread engagement in both pieces of wood for the duration of the joint,” one account said.
At its website (heco-schrauben.de), the company reports the following about its Heco Unix screw, which includes the characteristic Heco saw-tooth profile on its lead threads, also features patented milling recesses under the head. “In contrast to the more common raised milling ribs, this design allows the countersunk head to sit tightly when used in a hinge or metal fitting while still aiding efficient countersinking and obviating splitting when used straight into wood.”
“Thanks to the variable thread pitch of the HECO-UNIX® screws the wooden components are pulled together as the screws are driven in. This permits the use of fully threaded screws without jigging the wood components together. Assembly tasks can therefore be completed much more quickly. Thanks to the full thread, components are also fixed in place axially. This prevents the negative effects of creeping und shrinking by wood when using part-thread screws. Furthermore, panels are completely secured even before the head is countersunk leading to a neater finish. Deep countersinking is no longer necessary. |
