DIN 7991 Stainless Steel M3-M24 Hex Socket Countersunk Head Machine
Screw
Description:
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. 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.
On the upper surface of the connector mounting hole formed with a
90 degree cone with a circular hole, flat head machine screws in
this round nest, and fittings flush with the surface. Flat machine
screws in some cases also have flat round head machine screws used
in this screw more beautiful, the surface may allow for a few
prominent place.
Screw plays a role in connecting two or more objects in daily life
or industrial manufacturing indispensable necessity.
Shen head screws (slotted), countersunk head bolts (with tongue)
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.

Application:
Countersunk head screws mostly used in the need to install a raised
surface of the part can not place the fastening parts there are two
kinds of thickness, the so-called thick, that is fastened to the
parts is greater than the thickness of the head of the countersunk
head screw thickness after tightening the screw, there is no part
of the screw threaded into the threaded hole. This situation,
certainly countersunk head screws tightened. Typically there is a
situation that is fastened to the part thickness smaller than the
height countersunk screw head, which is common in sheet metal parts
in machinery and equipment, such as a hinge and the cabinet doors
and the coupling of the chassis; sheet metal equipment housing and
coupling devices and so on. Due to the small thickness of the part,
are fastened sheet metal parts, screws vias completely into a
conical bore, in this case, when the countersunk screw is
tightened, the screw head is not pressed sheet metal cone , but the
top of the screw head and a threaded hole at the bottom of the root
Jisi, although the feeling screw is tightened, but the sheet metal
is pressed instead of being stuck in this situation, although
feeling tighten the screws, but the sheet metal parts really have
not been tightened. This is a very common situation.
To tell you the reason for working on: countersunk screw head round
vertebrae was 90 ° cone angle, usually bought a new drill apex
angle was 118 ° -120 °, the lack of training of some of the workers
do not know the angle difference, one often the direct use of
reaming drill 120 °, which resulted in not Shen head screws tighten
head conical surface difficult, but the bottom line of the screw
head is difficult, which is the so-called head screws tight could
not reason
