Manufacturing process of Duplex Steel Hex Screws

 

There is a huge variety of fasteners in duplex steel and it depends on type of fasteners you need to manufacture to adopt the manufacturing it. For example Hex bolt is a kind of fasteners and for manufacturing it we need plain bar. There are two process to manufacture these DS Bolts i.e Cold forming process as well as hot forming process, threads on duplex steel Hex Screws one is of thread rolling process and second is chezer threading. Second process is out dated and rarely sued while the first process is universally accepted and quality process.

 

Quality Check of Duplex Steel Hex Screws

There are many points check while manufacturing to delivery of duplex steel Hex Screws. Since Hex Screws can be manufactured in three ways the quality check of these fasteners will be accordingly.

Weather it is duplex steel Hex Screws or it is nickel alloy Hex Screws or even stainless Hex Screws, the quality check for all the Hex Screws remains same. The first and foremost thing in quality check of these Hex Screws is uniformity of threading pattern so that the nuts or the object where these Hex Screws are suppose to be fitted should neither be loose nor there should be any problem while fitting it. .
