Hexagonal mabhaudhianoshandiswa kusunga nhengo dzesimbi pamwechete. Iwo anowanzo shandiswa mukuvaka, muchina uye mota application. Iyo bhaudhi yehex musoro inobvumira kuomesa nyore uye kusunungura ne wrench kana socket, zvichiita kuti ive sarudzo yakakurumbira yekuchengetedza zvinorema zvikamu.

Kuyera metric bhaudhi, unofanirwa kuona dhayamita, pitch, uye kureba.

1. Diameter: Shandisa caliper kuyera dhayamita yebhaudhi. Semuenzaniso, kana iri M20 bhaudhi, dhayamita iri 20mm.

2. Thread pitch: Shandisa pitch geji kuyera chinhambwe chiri pakati peshinda. Izvi zvichakubatsira kuona tambo yeshinda, iyo yakakosha pakufananidza bhaudhi kune nati chaiyo.

3. Kureba: Shandisa mutongi kana tepi kuyeresa kureba kwebhaudhi kubva pasi pemusoro kusvika kumuromo.

Nekunyatso kuyera zvinhu zvitatu izvi, unogona kuona uye kusarudza iyo chaiyo metric bolt kune yako chaiyo application.

"TPI" inomirira "shinda pa inch." Chiyero chinoshandiswa kutaridza huwandu hweshinda dziri mubhaudhi imwe inchi imwe kana sikuruu. TPI chinhu chakakosha chekufunga kufunga kana uchifananidza mabhaudhi nenzungu kana kuona tambo dzakarukwa kuenderana. Semuenzaniso, 8 TPI bhaudhi zvinoreva kuti bhaudhi rine 8 tambo dzakakwana mune imwe inch.

Kuti uone kana bhaudhi iri metric kana imerial, unogona kutevedzera izvi zvakajairika nhungamiro:

1. Measuring system: Tarisa mabhii pamabhaudhi. Metric bolts anowanzo kunyorwa netsamba "M" inoteverwa nenhamba, yakadai seM6, M8, M10, zvichingodaro, zvichiratidza dhayamita mumamirimita. Mabhaudhi eImperial anowanzo kunyorwa nechidimbu kana nhamba inoteverwa ne “UNC” (Unified National Coarse) kana “UNF” (Unified National Fine), zvichiratidza shinda chiyero.

2. Thread pitch: Inoyera chinhambwe chiri pakati peshinda. Kana kuyerwa kuri mumamilimita, ingangove metric bolt. Kana kuyerwa kuri mushinda pa inch (TPI), ingangoita bhaudhi yeumambo.

3. Mavara emusoro: Mamwe mabhaudhi anogona kunge aine mavanga mumisoro yawo kuratidza giredhi kana mwero. Semuyenzaniso, metric mabhaudhi anogona kunge aine micherechedzo yakaita se8.8, 10.9, kana 12.9, ukuwo mabhaudhi ehumambo anogona kunge aine mamark senge “S” kana mamwe magiredhi mamaki emabhaudhi ezvimiro.

Nekutarisisa zvinhu izvi, unogona kuona kana bhaudhi iri metric kana yehumambo.
