Information

The mechanical properties test of Countersunk Head Phillips Self Dilling Screws is briefly described as follows:

Countersunk Head Phillips Self Dilling Screws

(1) The screw-in performance test is to screw the screw sample into the test plate until one complete thread completely passes the test without breaking.

(2) The destructive torque test is to clamp the stem of the Countersunk Head Phillips Self Dilling Screws test piece in a screw mold or other device that matches the screw thread, and uses a calibrated torque-measuring device to measure it. Countersunk Head Phillips Self Dilling Screws Torque until they break, breakage should not occur on the part of the thread being clamped.

(3) Carry out a tensile test on the Countersunk Head Phillips Self Dilling Screws sample to check the minimum tensile load for failure. The fracture should be within the length of the rod or the unscrewed thread, and should not occur at the junction of the nail head and the rod. Before the sample breaks, it should be able to reach the minimum tensile load specified in the corresponding performance class.
