Kukula kwa nsonga kumayikidwa ndi mtengo wa 1 mpaka 5, womwe umasonyeza makulidwe a chitsulo chachitsulo chomwe phula lingalowemo - 1 imayimira chitsulo chochepa kwambiri ndi 5 chokhuthala. nsonga yodziwika bwino ya Self Drilling Screw ndi zomangira za Thread 3, 4 ndi 5 ndizodziwika kwambiri pama projekiti aliwonse ogwiritsa ntchito zitsulo zokhuthala.

Zomangira za ulusi 1 zidapangidwa kuti zizigwiritsidwa ntchito padenga ndi zolumikizira zachitsulo ndi matabwa. Zomangira izi zimakhala ndi kabowo kakang'ono kwambiri, zomwe zikutanthauza kuti amapanga dzenje lokhala ndi mainchesi ochepa kwambiri kuposa ulusi wakunja womwe umakhala pa screw. Ndi kabowo kakang'ono, ulusi ukhoza kuluma muzinthu kuti ugwire bwino.

Self Drilling Screws amasiyanitsidwanso ndi mtundu wamutu. Pali mitundu iwiri yodziwika bwino ya mitu ya Self Drilling Screws:

• Mutu wa washer wa Hex: Umakhala ndi makina ochapira omangidwira kuti azigawa bwino zolemetsa ndi zolemetsa kudera lalikulu. Kalembedwe kameneka ndi koyenera kwa ntchito zofolera ndi ntchito zina zolemetsa.
• Zosintha: Zimakhala ndi mutu wokulirapo wa dome ndi flange kuti apange malo okulirapo pansi pamutu kuti azitha kunyamula.

Kupatula apo, masitayelo ena onse amitu pa zomangira zodzibowolera nthawi zambiri amakhala ndi Phillips drive, yomwe imathandiza kuyendetsa wononga mowongoka. Ma square drive akuchulukirachulukira, chifukwa chocheperako sichingazembere poyendetsa. Phillips pan-head Self Drilling Screws ndi yabwino kwa ntchito zopepuka.

Mtundu wina wodziwika bwino wa screw ndi screw-head screw, yomwe imagwiritsidwa ntchito mukafuna malo osambira. Self Drilling Screws yokhala ndi mapiko - ndiye nkhuni zomaliza mpaka zomangira zachitsulo.

Nthawi zambiri timafunsidwa zomangira zitsulo zosapanga dzimbiri. Zilipo, koma malangizowo si abwino kwambiri pobowola muzitsulo zosapanga dzimbiri. Pazogwiritsa ntchito zitsulo zosapanga dzimbiri, timapereka Bi-metal Self Drilling Screws, pomwe thupi la wononga ndi chitsulo chosapanga dzimbiri, ndipo nsonga yake ndi yachitsulo cha kaboni, chomwe chimalola kuti zomangirazo kubowola muzitsulo zosapanga dzimbiri mosavuta.

Muyenera kuyang'ananso tsamba lathu pansipa kuti mudziwe zambiri zomwe zingakuthandizeni kudziwa wononga bwino kwambiri polojekiti yanu yotsatira.
