Technical Examples

A device for tension rods or attachment bolts for snare drums. The threaded tension rod or bolt may be a threaded locking bolt. In this way, the vibration caused by use of the drum does not lead to disengagement of the attachment means, or disengagement of the nuts from the tension rods. In these self-locking bolts, tension rods, or fasteners, a portion of the helical screw thread is replaced with a pliant member such as a polymer, and when the fastener is tightened, the polymer friction-fits to the threaded hole within the attachments means or nuts, rendering the fastener difficult to remove.
