1. Pfungwa
Bolt yekunze ine hexagonal chinhu chinoshandiswa nesimbi, chinozivikanwawo se screw yekunze ine hexagonal, screw yekunze ine hexagonal kana bholt yekunze ine hexagonal.

2. Kurapa pamusoro
Mukugadzirwa kwemabhoti, kugadziriswa kwenzvimbo ndeimwe yenzvimbo dzinodiwa zvikuru. Inogona kuita kuti nzvimbo yebhoti isvike pane zvinodiwa uye kuvandudza kuramba kwayo ngura, simba rayo uye runako rwayo.
Kune nzira dzakawanda dzekurapa pamusoro pemabhoti, dzakajairika ndedzinotevera:
Kugadzira Magetsi: Mabhoti anonyudzwa mu zinc solution, uye zinc inoputirwa pamusoro pebhoti ne layer kuburikidza ne electrochemical reaction, zvichiita kuti dzisapararire ngura uye dzisapararire ngura.
Kupisa-kunyika: Mushure mekunge mabhoti agadzirwa, anonyudzwa mumvura yakanyungudutswa yezinc, uye zinc layer inoumbwa pamusoro kuburikidza nemakemikari kuti ipe mhedzisiro inodzivirira ngura, inodzivirira ngura nezvimwe.
Kurapa kwerima: Firimu resimbi nhema rinoumbwa pamusoro pebhoti kuburikidza nemakemikari kuti rirambe richidzivirira ngura.
Kurapa nephosphate: Nyika bhoti mumushonga wephosphate kuti ugadzire phosphate pamusoro kuti irambe yakasimba.
Kugadzirisa kuomarara: Kuburikidza nekupisa kana kupfapfaidza pamusoro, jira rekufukidza rine kuomarara kwakanyanya rinoumbwa pamusoro pebhoti kuti riwedzere kusimba kwayo uye kuramba kwayo kusimba.
Idzi ndidzo nzira dzakajairika dzekurapa pamusoro pemabhoti. Nzira dzakasiyana dzekurapa dzinoenderana nemamiriro akasiyana ekushandiswa uye zvinodiwa. Paunenge uchirapa pamusoro pemabhoti, zvinofanirwa kuitwa zvichienderana nezvinodiwa uye zvakatemwa kuti uve nechokwadi chekuti mabhoti akabatwa anosangana nezvinodiwa zvekushanda.

3. Kushanda kwedanho
Chiratidzo che performance grade che external hexagonal bolt chine zvikamu zviviri zvenhamba, izvo zvinomiririra nominal tensile strength value pamwe ne yield strength ratio yezvinhu zvebolt.
Semuenzaniso, bhaudhi rine performance level 4.6 rinoreva:
a. Simba rekudhonza rechinhu chinobatidza bhoti rinosvika 400MPa;
b. Chiyero chesimba remuboti wezvinhu zvinoshandisa bhoti i0.6;
c. Simba remuboti rinosvika 400×0.6=240MPa
Mabhaudhi ane simba guru 10.9, mushure mekupisa, anogona kuita zvinotevera:
a. Simba rekudhonza rechinhu chinobatidza bhoti rinosvika 1000MPa;
b. Simba remuboti rinosvika 1000×0.9=900MPa.

4. Musiyano uripo pakati pemabhaudhi ekunze ane hexagonal akajairwa uye mabhaudhi ekunze ane hexagonal akasimba kwazvo
Mabhaudhi akajairika ane mashefu matanhatu anogona kushandiswazve, asi mabhaudhi ane simba guru haagoni kushandiswazve.
Mabhaudhi ane simba guru anowanzogadzirwa nesimbi ine simba guru Nhamba 45 (8.8s), 20MmTiB (10.9S), uye mabhaudhi ane simba guru. Kune mhando dzekukweshana, shandisa chipanera chetorque kuisa prestress yakatarwa, uye kune mhando dzinotakura kumanikidzwa, sunungura musoro wetorx. Mabhaudhi akajairwa anowanzogadzirwa nesimbi yakajairika (Q235) uye anongoda kusimbiswa chete.
Mabhaudhi akajairika anowanzova egiredhi 4.4, giredhi 4.8, giredhi 5.6 uye giredhi 8.8. Mabhaudhi ane simba guru anowanzova egiredhi 8.8 uye giredhi 10.9, uye giredhi 10.9 ndiyo inonyanya kushandiswa.
Maburi ezvikururu zvemabhaudhi akajairwa haasi makuru kupfuura emabhoudhi ane simba guru. Kutaura zvazviri, maburi emabhaudhi akajairwa madiki.
