Self-drilling screws ane akawanda akasiyana maumbirwo emusoro, uye vanhu vazhinji havazivi kuti maumbirwo emusoro akasiyana ane mabasa akasiyana. Pakati peanozivikanwa pasi rose Self-drilling screws misoro yemhando, pane akati wandei anowanzo shandiswa mhando mhando, imwe neimwe ine mabasa akasiyana:

1. Flat head: chigadziro chitsva chinogona kutsiva musoro wakatenderera uye musoro wehowa. Musoro une dhayamita yakaderera uye dhayamita yakakura. Pane misiyano midiki mumhando.

2. Musoro wedenderedzwa: Ndiwo wainyanya kushandiswa chimiro chemusoro kare.

3. Musoro wePan: Uye dhayamita yeiyo standard flat dome column musoro idiki pane iyo yemusoro wedenderedzwa, asi yakanyanya kukwirira nekuda kwehukama pakati pekudzika kwegorofu. Iyo dhayamita diki inowedzera kumanikidza kunobata pane diki nzvimbo, iyo inogona kubatanidzwa zvakasimba neflange uye kuwedzera hurefu. surface layer. Inogona kushandiswa zvinobudirira mumakomba akacherwa mukati nekuda kwekuiswa kwemusoro mudhiri yekudhiraivha seti kuti ive nechokwadi chepakati.

4. Musoro weTruss: nokuti musoro wakanyorwa uye kupfekedzwa kwezvikamu zvetambo kunopera simba, kunonyanya kushandiswa mumagetsi emagetsi uye tepi rekodhi, uye inopa humwe hunobudirira hunoita pamusoro pemhando yepakati nepamusoro. Inokwezva dhizaini mhando.

5. Musoro wakakura wakatenderedzwa: Unonziwo oval-top wide-brimmed head, imusoro wakaderera, wakagadzirwa zvine hungwaru musoro wakakura-dhayamita. Inogona kushandiswa kuvhara mapepa esimbi maburi ane madhayamita akakura apo kushivirira kwakasanganiswa kwezvimwe zviito kunobvumira. Inokurudzirwawo kushandisa musoro wakatsetseka panzvimbo.

6. Hexagon socket head: knot ine wrench musoro urefu uye hexagonal musoro saizi. Iyo hexagonal shape yakanyatso kutonhora-yakaumbwa ne reverse-hole mold, uye pane zviri pachena kuora mwoyo pamusoro pemusoro.

7. Hexagon washer musoro: Yakafanana neyakajairwa hexagonal gomba-inotakura mhando yemusoro, asi panguva imwe chete, kune washer pamusoro pezasi pemusoro kudzivirira kupedzwa kwegungano uye kudzivirira chipanera kubva pakukuvadzwa. Dzimwe nguva kushanda kwechimwe chinhu kunokosha kupfuura chitarisiko.

8. Hexagona musoro: Iyi imhando yemhando umo torque inobata pamusoro wehexagonal musoro. Iine hunhu hwekuchekeresa makona akapinza kuti avhare kune tolerance range. Yakakurudzirwa kushandiswa kwekutengeserana kwese uye inowanikwa mumhando dzakasiyana-siyana dzemaitiro uye madhayamita eshinda. Nekuda kwemaitiro echipiri anodiwa, inodhura kupfuura yakajairwa hexagonal sockets.

9. Musoro we Countersunk: iyo yakajairika angle ndeye 80 ~ 82 madhigirii, iyo inoshandiswa kune fasteners iyo nzvimbo inoda kusungirirwa zvakasimba. Nzvimbo yekutakura inopa hutano hwakanaka.

10. Oblate countersunk head: Ichi chimiro chemusoro chakafanana neyakajairwa flat-top countersunk musoro, asi inonyanya kushandiswa. Mukuwedzera, iyo yakatenderedzwa uye yakatsvinda pamusoro pepamusoro inokwezva zvakare mukugadzira.
