Duplex screws

Duplex Screws

A duplex screw is a metal pointed pin having a raised helical thread. The Duplex Screws has a slotted head that joins things together by rotating them using a wrench or screwdriver. These screws can create either a permanent or temporary connection. The UNS S31803 Self Tapping Screw are designed having different types of heads. These screws are designed with a superior chemical content of chromium, nickel, molybdenum, and other alloys. Duplex Steel Grub Screw have outstanding resistance to corrosion and toxic affluents. These screws bolster superior strength and tolerances. A UNS S32205 Hex Head Cap Screw has austenitic and ferritic microstructure grades. These screws have a lower thermal expansion with a higher thermal conductivity.
