Distance limiting nut

Abstract

The invention discloses a distance limiting nut. A body is provided with six outer side faces, limit slots are formed in at least two outer side faces, all the limit slots are positioned in the same cross section, so that bolts with the same nominal diameter cannot penetrate an internal thread hole of the cross section with the limit slots, and the axial distance between each limit slot and each end opening of the internal thread hole is longer than 2mm. The distance limiting nut has the advantages that the limit slots are formed in the outer side faces of proper positions of the nut body, sothat the thread hole slightly deforms in the cross section with the limit slots, the nut cannot be screwed into a stud after being screwed to a certain depth when the stud is matched with the nut, accordingly, the distance between the nut and the end of the stud is fixed, every nut can be screwed to the same depth, the quality of a whole product can be stably controlled, in addition, the axial distance between each limit slot and each end opening of the internal thread hole is longer than 2mm to ensure enough matching distance between the nut and the stud, and enough matching strength of the nut and the stud can be ensured.

Description

technical field [0001] The invention relates to a spacer nut. Background technique [0002] The nut is an accessory of the fastener, and when applied, the nut cooperates with the stud to form a detachable connection. When assembling or disassembling the nut, a tool is generally used to rotate the nut, so as to assemble the nut with the stud or remove the nut from the stud. [0003] For some places with special requirements, there are requirements for the pressure of the clamping parts, which cannot be too loose or too tight. This requires that the screwing depth of the nut and the stud must be fixed. In the past, the nut was rotated by the experience of the worker, but the error If it is relatively large, it will have a great impact on product quality. In addition, under some severe conditions, the nuts and studs will die after a long time of use, and the nuts are generally hexagonal nuts. Using a hexagonal wrench will cause slippage, resulting in the nuts being unable to ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a distance-limiting nut, which can effectively solve the problem that the matching depth of existing nuts and studs depends on the experience of workers, and there is no uniform standard, which leads to the problem that the product quality cannot be guaranteed.
