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. Tightening Procedure: Insert the key into the socket and apply the torque on the nut while holding the key.

Screws are differentiated according to a few characteristics: head shape, head type, thread proximity, thread gauge, length and diameter. The most common head shapes are flat head and countersink.

countersink diameters are based on the theoretical maximum head diameter at a depth of .005 to .015 and an angle of 82 degrees. actual depth may vary depending on actual head diameter and angle countersink diameter tolerances are +/- .010 countersink angle tolerances are +/- 2 degrees free should be used unless close is required

Compare the Yamaha FZ25 Vs Suzuki Gixxer SF 250 Vs Honda CBR 250R on CarAndBike to make an informed buying decision as to which bike.A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter for external thread and the minimum diameter for internal one) and the pitch P, both expressed in millimetres and separated by the hyphen sign, -(e.g., M8-1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ISO 262, it can be omitted (e.g., M8).

Our standard for the diameter for the top of the countersink is to take the middle of the range for the nominal dimension with a tolerance of plus or minus .010. For example for a #8 flat head screw in .042 thick material, we would punch a .263 diameter hole and countersink to .320 (.332 plus .308 divided by 2) plus or minus .010.
