Tapping screw: mechanical performance requirements:
1, the core hardness: standard value HRC28-38.When the test is taken from the tail of 1-2 times the diameter of the section, if the name is too short, can be embedded first, and then test the hardness.
2, surface hardness: standard MIN HV450.
3, carburized layer: the standard 4 # and 6 # : 0.05-0.18 mm, 8 #, 12 # : 0.10-0.23 mm, # 14:0.13 to 0.28 mm.The main purpose of carburizing is to enhance the surface hardness and ensure the strength of teeth. If the decarburization is too deep and the carburization is insufficient, the strength of teeth will not meet the requirements, that is, when the screw into the test, the teeth will be damaged.
4, torsion: standard grid 4#5#6#7#8#10#12#14#A tooth 14212835455696145AB tooth 142128354565102165.
5, screw into the test: the self tapping nail screw into a reserved test hole in the steel plate, the self tapping nail should be formed in the test plate to match the thread, and the screw itself does not deformation and damage, until the end of the taper thread completely tested plate.The screw in test is only applicable to type AB, B, BP self-tapping nails.IFI stipulates: the test board is prepared by semi-hard low-carbon cold rolled steel, and the hardness of the steel plate is Rockwell 70-85HRB.Standard specification of steel plate, i.e., thickness, is shown in the table below. The test hole should be punched or drilled, and the tolerance is the specified nominal diameter (see table below)±0.025mm.
