Self-tapping screw kuvaka. Imwe yega yega yega-tapping screw inoumbwa nezvikamu zvitatu: musoro, tsvimbo uye kupera kwetsvimbo. Imwe neimwe self tapping screw inoumbwa nezvinhu zvina: chitarisiko chemusoro, nzira yekudhonza, mhando yeshinda, nzira yemuswe.
1. Chitarisiko chemusoro
Misoro inouya mumhando dzose uye nehukuru. Kune muromo wakatenderera (hafu yemusoro wepamusoro), musoro wedenderedzwa, wakatenderedza muromo flange (ine padhi), flat denderedzwa musoro flange (ine pad), pani musoro, pan musoro flange (ine pad), countersunk musoro, hafu countersunk musoro, cylindrical. musoro, spherical cylindrical top, nyanga musoro, hexagonal musoro, hexagonal flange musoro, hexagonal flange (ine pad).
2. Kudhonza nekumonyorora nzira
Screw way inoreva kuisirwa uye kusungirira screws kana screw musoro kukanganisa fomu, chaizvo kune ekunze screw uye yemukati screw nzira mbiri. Kazhinji kutaura, wrench yekunze inobvumira torque yakakura kupfuura chero ipi zvayo yemukati wrench (concave groove). External wrench: hexagonal, hexagonal flange surface, hexagonal flange, hexagonal ruva chimiro, etc. Internal screw: one groove, cross groove H type, cross groove Z type, cross groove F type, square groove, compound groove, inner spline, inner hexagon patani, yemukati katatu, yemukati hexagon, yemukati 12 Angle, clutch groove, matanhatu mashizha groove, yakakwira torque cross groove, nezvimwe.
3. Screw thread type
Kune mhando dzakawanda dzeshinda, shinda yekubaya (yakafara mazino), shinda yemuchina (chakawanda), drywall screw thread, fiberboard screw thread, uye imwe shinda yakakosha. Mukuwedzera, shinda inogona kupatsanurwa kuita imwe pitch (mbiri musoro), kaviri pitch (multi-head), multi-pitch (double-head) uye ingani mazino akawanda-musoro shinda.
4, nzira yekupedzisira
Iyo muswe yekupedzisira modhi inonyanya kusanganisira maviri marudzi: cone end uye hushamwari kupera. Nekudaro, zvinoenderana nezvinodiwa zvechikumbiro, iyo yekusimbisa chikamu pamuswe wemuswe inogona kuburitsa uye kugadzirisa iyo inoshanda groove, groove, ronda kana chikamu chakafanana nechimiro che twist drill, etc. Mune mamwe maitiro, imwechete cone inopera kana sandara magumo, kune nzira dzakasiyana dzakadai sekutenderera muromo kupera.
