1.What is an external hexagon bolt?
To know the external hexagonal bolt, it is necessary to know its appearance structure first. The head of the external hexagonal bolt is hexagonal, and the shank is threaded. Generally, the shorter one is full threaded and the longer one is half threaded. In fact, whether it is a full tooth or a half tooth, its function is the same. The standards of full-tooth external hexagon bolts and half-tooth external hexagon bolts are also different, including full-tooth (ISO 4017/GB 5783/DIN 933) and half-tooth (ISO 4014/GB 5782/DIN 931).
2.What are the characteristics of hexagon bolts?
has a large pre-tightening contact area and can use a large pre-tightening force. Generally, it is used in large equipment, and its price is lower than that of the internal hexagon. The disadvantage is that it takes up a large space and cannot be used in counterbores.
3.How to use external hexagonal screws?
General adjustable wrench, ring wrench and open-ended wrench are used for assembly. The adjustable wrench has low assembly efficiency, but strong versatility, and is suitable for external hexagonal screws with various head specifications. The efficiency of the ring spanner is high, but it is not suitable for some occasions. A ring spanner has only two heads, so it can only be used on external hexagonal screws with two different heads. Open-ended wrenches are similar to ring wrenches, but they can lengthen sleeves.
4.Which mode of transportation will be better?
Generally speaking, the production volume is large, so we suggest shipping, and we respect your views on other modes of transportation.
