1.Kwemera
Bolt yo hanze ya hexagonal ni ibikoresho byuma, bizwi kandi nkumugozi wo hanze wa mpande esheshatu, umugozi wo hejuru wa mpande esheshatu cyangwa uruzitiro rwo hanze.

2.Ubuvuzi bwo hejuru
Mubikorwa byo gukora bolts, kuvura hejuru nimwe mumihuza yingirakamaro. Irashobora gutuma ubuso bwa bolt bwujuje ibisabwa kandi bugateza imbere kurwanya ruswa, imbaraga nuburanga.
Hariho ubwoko bwinshi bwuburyo bwo kuvura hejuru ya bolts, ibisanzwe nibi bikurikira:
Galvanizing: Bolt yibizwa mumuti wa zinc, kandi zinc itwikiriwe hejuru yumurongo wa bolts kumurongo ukoresheje reaction ya electrochemicique, bigatuma idashobora kwangirika kandi ikarwanya ruswa.
Gushyushya ibishyushye: Nyuma yo gukora ibihingwa, byinjizwa mumazi ya zinc yashongeshejwe, hanyuma hakabaho urwego rwa zinc hejuru yubutaka hifashishijwe imiti kugirango igere ku kurwanya ingese, irwanya ruswa nizindi ngaruka.
Kuvura umwijima: Filime yumukara wa okiside ikozwe hejuru ya bolt hifashishijwe imiti kugirango irusheho kwangirika.
Kuvura fosifati: Shira Bolt mumuti wa fosifati kugirango ukore firime ya fosifati hejuru kugirango irusheho kurwanya ruswa.
Kuvura gukomera: Binyuze mu kuvura ubushyuhe cyangwa gutera hejuru, hashyizweho urwego rwo gutwikisha hamwe nuburemere bukabije hejuru ya bolt kugirango rwongere imbaraga kandi rwambare imbaraga.
Ibyavuzwe haruguru nuburyo busanzwe bwo kuvura. Uburyo butandukanye bwo kuvura buhuye nibisabwa bitandukanye. Mugihe ukora ubuvuzi bwa bolt, bugomba gukorwa hubahirijwe ibipimo ngenderwaho hamwe nibisobanuro kugirango hamenyekane ko ibivurwa byavuwe byujuje ibyangombwa bisabwa.

3. Imikorere y'urwego
Ikirangantego cyimikorere ya label ya hexagonal yo hanze igizwe nibice bibiri byimibare, igereranya nominal tensile imbaraga zingirakamaro hamwe numusaruro wimbaraga yibikoresho bya bolt.
Kurugero, bolt ifite urwego urwego 4.6 bisobanura:
a. Imbaraga za nominal tensile imbaraga za bolt igera kuri 400MPa;
b. Ikigereranyo cy'umusaruro-imbaraga wibikoresho bya bolt ni 0,6;
c. Imbaraga zumusaruro wizina ryibikoresho bya bolt bigera kuri 400 × 0,6 = 240MPa urwego
Urwego rwimikorere 10.9-imbaraga-zikomeye, nyuma yo kuvura ubushyuhe, irashobora kugeraho:
a. Imbaraga za nominal tensile imbaraga za bolt igera kuri 1000MPa;
b. Imbaraga zumusaruro wizina ryibikoresho bya bolt bigera kuri 1000 × 0.9 = 900MPa.

Ibisanzwe bya mpandeshatu zishobora gukoreshwa, ariko imbaraga-ndende ntishobora gukoreshwa.
Bolt ifite imbaraga nyinshi muri rusange ikozwe mubyuma bikomeye cyane No 45 ibyuma (8.8s), 20MmTiB (10.9S), kandi ni ibyamamare. Kubwoko bwo guterana amagambo, koresha umurongo wa torque kugirango ushyire icyubahiro cyihariye, naho kubwoko butwara igitutu, kura umutwe wa torx. Ibisanzwe bisanzwe bikozwe mubyuma bisanzwe (Q235) kandi bigomba gukenerwa gusa.
Ibisanzwe bisanzwe mubyiciro 4.4, icyiciro 4.8, icyiciro 5.6 nicyiciro 8.8. Imbaraga zikomeye cyane murwego rwa 8.8 nicyiciro 10.9, hamwe nicyiciro 10.9 nicyo gikunze kugaragara.
Imyobo ya screw ya bolts isanzwe ntabwo byanze bikunze iruta iy'imbaraga zikomeye. Mubyukuri, ibyobo bisanzwe bya bolt ni bito.
