Abstract
A screw with a threaded shaft which has a slot running lengthwise dividing the threaded shaft into two shaft halves. A deformable mass is provided in the slot and fills the slot. This mass prevents the screw threaded into a threaded hole or application-related cored hole from loosening by itself.
Claims12
A screw comprising:
- a threaded shaft having a slot running along a longitudinal axis of the screw and dividing the threaded shaft into at least two resilient shaft portions comprising means for allowing the shaft portions to be pushed together when the screw is pushed at first axially into a threaded hole whereby threads of the screw slip over threads of the hole by the shaft halves approaching each other;
- and
- wherein a mass at least partially fills the slot and is deformable to such an extent that it substantially does not interfere with the approaching of the shaft halves when the threaded shaft is pressed into the threaded hole.
