What is stainless steel hexagon screws?

 

Stainless steel hexagon screws, in fact, there are a lot of calls, it is called hex bolts, also can be called hex screws or hex bolts, everyone used to call different. There are three kinds of ordinary bolts: A, B and C. The first two are refined screws, less used. Generally speaking, ordinary screws are C-class ordinary screws.

Stainless steel hexagon screws are used with nuts for fastening connected parts and components with two through-holes. It is a bolt that is often used. There are A class and B class external hexagonal use more, more important, and in the assembly precision requirements of high, as well as subjected to greater impact, vibration or cross rate load occasions used more. Class C is used for rough surface, assembly precision requirements are not high. The thread on the outer hexagon screw is generally the common thread of fine teeth, and the self-pin of the common thread of winding teeth is good. It is mainly used for thin-wall parts or occasions when they are impacted, vibrated or under alternating load. General outer hexagon screws are made of part of the thread, the full screw is mainly used for nominal length of the short outer hexagon and the need for longer thread occasions.

Stainless steel hexagon screws with holes are used where outer hexagon screws are required to be locked. Hinged hole screws can precisely fix the phase to the position of the connected parts and can be shearing and extruding by the die force.
