Screws with strong pull-out strength have been sought for the treatment of cancellous bone. We hypothesized that an obliquely angled screw thread has advantages over conventional vertical thread with ...

The authors conducted a study to determine the thread properties that provide optimal screw fixation in cancellous bone, when screws of the same external screw diameter are used. Screw thread Type 1, ...

The screw jack works by reciprocating the handle, which rotates a rod to drive the nut, causing the lifting screw to rotate and raise or lower the lifting cup, thus achieving the lifting and pulling ...

A new screw uses a special tip and thread form start that eliminates cross threading . The ‘MAThread’ screw from Arnold Umformtechnik has a ‘dog point’ that ensures optimum feed into the application.
