Abstract
A hexagonal head bolt is composed of a flat-top tip, a screw neck, a screw, and the like. The cup-head tip, the screw neck and the screw are integrated. The position where the flat-top tip is connected with the screw is designed to be of an R-corner structure. A section of screw neck is arranged on the upper portion of the screw, wherein screw teeth are not arranged on the screw neck. Round screw teeth are arranged on the lower portion of the screw, and the round screw teeth are arranged at the same angle. A screw pin head of the lower portion of the screw is provided with a 28-degree chamfer. The hexagonal head bolt is stable, long in fastening lasting time, durable, compact in structure, and good in practical effect.
Description
Technical field:
The utility model relates to a kind of screw, is specifically related to a kind of hexagon head bolt.
Background technique:
It is very widely that hexagon head bolt uses at machinery industry, and hexagon head bolt generally is fixed in equipment component, but in long-term using process, owing to being subjected to external force or equipment vibrations itself, bolt is occurred loosening, causing major safety risks when serious, give user's economic loss.
The model utility content:
For the technical deficiency of existing the said goods, the purpose of this utility model is to provide a kind of hexagon head bolt, and it is comprised of flat-top termination, spiral shell neck, screw rod etc.
The technological scheme that its technical problem that solves the utility model adopts is: cup head termination, spiral shell neck, screw rod are the integral type structure, flat-top termination and screw rod joint are designed to the R corner structure, the screw rod epimere is provided with a joint spiral shell neck, thread is not set on the spiral shell neck, the screw rod hypomere arranges circular thread, and each circular thread is the arrangement with angle, and the screw rod ailhead of hypomere screw rod is provided with 28 ° of chamferings.
The beneficial effects of the utility model are: stable, fastening time lifetime is long, durable, compact structure, good practical effect.
Description of drawings:
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model flat-top end structure schematic diagram;
In figure, 1, flat-top termination 2, spiral shell neck 3, screw rod 4, screw rod ailhead
