The model utility content:
The purpose of this utility model is at the deficiencies in the prior art, a kind of band pad hexagonal socket head cap screw is provided, this screw intensity and precision height, effectively improve stability, assembling applicability, Security and the long-acting usability of machinery running, and be serially connected with plain washer and play packing ring, reduce the assembling work amount, improve efficiency of assembling.
For achieving the above object, the utility model is achieved through the following technical solutions: band pad hexagonal socket head cap screw, comprise the screw cap and the lead screw that connect as one by joint, this band pad hexagonal socket head cap screw is the screw through the zinc-plated processing of surface black, and lead screw is provided with the screw thread that accuracy of thread is 5g6g, be serially connected with plain washer and play packing ring at described joint, play packing ring near screw cap one end, plain washer is near lead screw one end.
Described screw cap is a cylindrical body.
Described screw cap left end offers hexagon ring.
Described worm tooth outer diameter D 3 values are 2.87mm~5.97mm, and screw thread effective diameter D2 value is 2.59mm~5.28mm.
Angle between the adjacent thread of described screw thread is 60 °.
Described threaded stem afterbody is provided with chamfering.
The utility model beneficial effect is: the utility model band pad hexagonal socket head cap screw is the screw through the zinc-plated processing of surface black, and lead screw is provided with the screw thread that accuracy of thread is 5g6g, be serially connected with plain washer and play packing ring at joint, play packing ring near screw cap one end, plain washer is near lead screw one end, so screw intensity and precision height, can effectively improve stability, assembling applicability, Security and the long-acting usability of machinery running, and be serially connected with plain washer and play packing ring, can be directly used in assembling, reduce the assembling work amount, improve efficiency of assembling.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a left view of the present utility model;
