Description

Stainless steel threaded fastener convenient to install fast Technical Field The utility model relates to the technical field of fasteners, in particular to a stainless steel threaded fastener convenient to install quickly. Background The threaded fastener is a connecting component widely applied to a plurality of fields of machinery, construction and the like, and is an indispensable connecting component in a plurality of fields of mechanical assembly, construction and the like, wherein the fastening connection between parts is realized through the matching of threads. In the installation process of the traditional threaded fastener, the problems of low installation speed, poor operation stability, easy loosening and the like often exist. Disclosure of utility model The present utility model aims to provide a stainless steel threaded fastener which is convenient to install quickly, and solves the problems in the prior art. In order to solve the technical problems, the technical scheme is that the stainless steel threaded fastener convenient to install rapidly comprises a screw rod and a screw head, wherein the screw rod comprises a full-thread locking section, a spiral groove fast-forward section and a conical guide head, a locking ring is sleeved on the surface of the full-thread locking section, an inner hexagonal driving groove is formed in the top of the screw head, two arc-shaped guide grooves are symmetrically formed in the side wall of the screw head, and a claw mechanism is arranged on the outer side of the screw rod. Preferably, the anti-loose ring is made of copper alloy, and the inner surface of the anti-loose ring is provided with zigzag threads matched with the full thread locking section. Further, the anti-loose ring is made of copper alloy, and the saw-tooth threads matched with the full-thread locking section are formed in the inner surface of the anti-loose ring, so that the anti-loose effect of the fastener in a locking state is enhanced through the material characteristic of the copper alloy and the engagement effect of the saw-tooth threads.
