A4-80 Stainless Steel 316 DIN 7991 hex Socket Countersunk Machine Screws
Hexagon Socket Countersunk Head Screws Machine Screws, which are also called hex bolts, cup head screws, socket head cap screws, its not the same name, but represent the meaning is the same. Commonly It is called hexagon socket head screws, then there are 4.8, 8.8, 10.9, 12.9. Also called SHCS, also called hex bolts. Its head is hex head, cylinder head also.Socket cap screws are a headed and externally threaded part designed for insertion through a close tolerance, internally tapped hole and mated with a nut. Tension on the socket cap screw is induced by rotation of the screw head. There is a hex socket in the head that accepts a hex wrench to tighten the socket cap screw. The point at the threaded end of the socket cap screw is machined flat so it will fit into a drilled hole. Flat head socket cap screws are similar in design to a button head.
Material stainless steel and iron. There are stainless steel SUS202 stainless steel hexagon socket head cap screws, this is an ordinary stainless steel material, there are stainless steel SUS304 hexagon socket head cap screws with stainless steel SUS316 hexagon socket head cap screws.
The most common stainless steel for general hardware use is stainelss steel 304, which is also called stainless steel 18-8.Stainless steel 316 is A highly corrosion resistant grade of stainless steel. Ideal in salt water and chlorine environments. More expensive than 18-8.
Flat head countersunk socket cap screws DIN 7991 are not intended for high strength application. The purpose of producing them with a strength of the property class 10.9 is to increase the wear resistance of the sockets. Insert the key into the socket and apply the torque on the nut while holding the key. Should however, the torque be applied on the screw itself it should be reduced accordingly.
