CSK Socket Head Allen Screw
SOCKET COUNTERSUNK HEAD CAP SCREWS | ALLEN CSK SCREWS – DIN 7991
Socket countersunk head cap screws are mostly used in applications that require an optically satisfactory fastener with minimum load-bearing capabilities. That is why these screws are not used in high-strength utilities. Sockets whose wear resistance is to be protected in the long run can use these screws instead of high-strength countersunk screws. By providing different finishes it is able to bear more wear and tear also make more corrosion resistant.
The practice to stiffen these in place on the surface is to apply the specific level of torque on the nut while inserting and holding the key into the socket. If there is not sufficient space on the surface for wrenches to create an opening for screws, then the head of these countersunk socket screws is in the neat sitting of the screws on the surface and in the smooth construction of structures.
CE offers screw-in stainless steel, carbon steel, and alloy steel.
