An introduction to the mechanical properties of Hex Flange Self Drilling Screw

(Summary description)Hex Flange Self Drilling Screw screw-in test: screw the self-tapping self-drilling screw into a steel plate with a reserved test hole, the Hex Flange Self Drilling Screw should form a matching thread in the test plate, and the thread of the screw itself No deformation or damage occurs until the end taper thread completely passes the test plate. The screw-in test is only applicable to AB, B, BP and other types of self-tapping and self-drilling screws.

Information

1. Hex Flange Self Drilling Screw screw-in test: screw the self-tapping self-drilling screw into a steel plate with a reserved test hole, the Hex Flange Self Drilling Screw should form a matching thread in the test plate, and the thread of the screw itself No deformation or damage occurs until the end taper thread completely passes the test plate. The screw-in test is only applicable to AB, B, BP and other types of self-tapping and self-drilling screws.

2. Carburizing layer of Hex Flange Self Drilling Screw: Standard 4#-6#: 0.05-0.18mm, 8#-12#: 0.10-0.23 mm, 14#: 0.13-0.28 mm. The main purpose of carburizing is to enhance the surface hardness and ensure the strength of the teeth. If the decarburization is too deep and the carburization is insufficient, the strength of the teeth will not meet the requirements, that is, the teeth will be damaged during the screw-in test.

3. Surface hardness of Hex Flange Self Drilling Screw: Standard MINHV450.

4. Torque of Hex Flange Self Drilling Screw: standard specification 4#5#6#7#8#10#12#14#A tooth 14212835455696145AB tooth 142128354565102165.

5. Hex Flange Self Drilling Screw core hardness: standard value HRC28-38. During the test, take the section 1-2 times the calling diameter from the tail. If the calling length is too short, it can be embedded first, and then the hardness can be measured.
