Abstract
A fastener is provided. The fastener, in the assembly of fasteners, prevents cross threading that occurs when an externally threaded fastener is threaded into a female fastener that is not axially aligned, and the method of production thereof is also provided. The fastener includes a shaft, a head, and a catching section.
Claims22
A fastener, comprising;
- a shaft, wherein the shaft comprises two parts that a body section and a coupling section and has a threaded portion comprising more than one thread with first and second minor diameters and first and second major diameters, and the threaded portion extends helically around an outer surface of the shaft starting at any level,
- a head, wherein the head transfers torque applied by a tool to the shaft for tightening and loosening,
- a catching section, wherein the catching section is adjacent to the shaft and guides the fastener, wherein
- the threaded portion extending helically around the shaft runs continuously from the body section to the coupling section of the shaft, and the threaded portion in the coupling section has threads, wherein a difference between the second minor diameter and the second major diameter decreases gradually towards the catching section.
1 more element
A fastener system configured to prevent cross threading, comprising;
- a female fastener, wherein the female fastener has a center hole where a continuous helical threaded portion with threads extends along the hole towards a longitudinal axis of the female fastener, and
- a male fastener, wherein the male fastener engages into the female fastener, wherein the male fastener comprises:
- a shaft, wherein the shaft comprises two sections that a body section and a coupling section, and has a threaded portion comprising more than one thread with first and second minor diameters and first and second major diameters, and the threaded portion extends helically around an outer surface of the shaft starting from any level,
- a head, wherein the head transfers torque applied by a tool to the shaft for tightening and loosening,
- a catching section, wherein the catching section is adjacent to the shaft and guides the fastener, wherein;
- the threaded portion extending helically around the shaft runs continuously from the body section to the coupling section of the shaft, and the threaded portion in the coupling section has threads, wherein a difference between second minor diameter and second major diameter decreases gradually towards the catching section.
