Description

Nut

Technical Field

The utility model relates to the technical field of fasteners, in particular to a nut.

Background

The nut is a nut, and is screwed together with a bolt or a screw rod to play a role in fastening, and one element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel, non-ferrous metals such as copper and the like according to different materials.

However, nut and bolt threaded connection back still have certain gap between them, if be used for outdoor fixed occasion, external rainwater infiltration to the screwed hole of nut, then lead to the bolt to rust, and the rust slag probably blocks up the gap between screw hole and the nut, then is difficult to follow the bolt with the nut and unscrews, accomplishes the dismantlement.

SUMMERY OF THE UTILITY MODEL
