Urwego rwimikorere ya Bolt, arirwo rwego rwimikorere ya bolt yo guhuza ibyuma, igabanijwemo amanota arenga 10, nka 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, nibindi. ibice bibiri, bigereranya nominal tensile imbaraga zingirakamaro hamwe no kugonda imbaraga zingana kubintu bya bolt.
Igisobanuro cyibikorwa bya bolt ni urwego mpuzamahanga rusanzwe, bolt yo murwego rumwe rwimikorere, tutitaye kubitandukanya nibintu byayo ninkomoko, imikorere yayo ni imwe, igishushanyo gishobora guhitamo gusa amanota yimikorere.
Imbaraga zo mu cyiciro cya 8.8 na 10.9 zerekana urwego rwo guhangayikishwa na bolt ni 8.8 GPa na 10.9 GPa 8.8 nominal tensile imbaraga za 800 n / 640 n yari nominal itanga imbaraga za bolts / muri rusange byagaragaye mumbaraga za "XY", X * 100 = imbaraga za bolt tensile, X * 100 * (Y / 10) = imbaraga zumusaruro wa bolt (nkuko biteganijwe mubirango: umusaruro / imbaraga zingana = Y / 10, aribyo 0. Y yerekanye) nkubunini bwa 4.8, imbaraga zingana za bolt ni: 400 mpa.Imbaraga zingirakamaro: 400 * 8/10 = 320MPa.Ikindi: ibyuma bitagira umuyonga mubisanzwe byanditseho A4-70, isura ya A2-70, bivuze ubundi gusobanura ibipimo: gupima uburebure kwisi uyumunsi hariho ubwoko bubiri bwingenzi, bumwe kuri sisitemu ya metric, igipimo cyo gupima ni metero (m), santimetero (cm), mm (mm), nibindi, muburayi, Ubushinwa n'Ubuyapani nubundi burasirazuba bwa Aziya ikoreshwa ni byinshi, ikindi nicyongereza, igipimo cyo gupima ahanini kuri santimetero (santimetero), gikoreshwa cyane muri Amerika, Ubwongereza no muburayi na Aibihugu bya merikani.1.Ibipimo bya sisitemu ya metero: 1m = 100 cm = 1000 mm2, gupima sisitemu yicyongereza: (8) 1 inch = 8 ints 1 inch = 25.4 mm
Bolt ikoreshwa muguhuza ibyuma byubaka bifite amanota arenga 10, harimo 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 na 12.9. igipimo cyingufu zingana yibikoresho bya bolt.Urugero: bolts hamwe nibikorwa bya 4.6, bivuze:
1. Imbaraga za nominal tensile imbaraga za bolt igera kuri 400MPa;
2. Ikigereranyo cyingufu zingana zigikoresho cya bolt ni 0,6;
3. Umusaruro w'izina imbaraga za bolt zigera kuri 400 × 0,6 = 240MPa icyiciro
Urwego rwimikorere 10.9 imbaraga nyinshi bolt, ibikoresho byayo nyuma yo kuvura ubushyuhe, birashobora kugeraho:
1. Imbaraga za nominal tensile imbaraga za bolt igera kuri 1000MPa;
2. Ikigereranyo cyingufu zingana zigikoresho cya bolt ni 0.9;
3. Umusaruro w'izina imbaraga za bolt zigera kuri 1000 × 0.9 = 900MPa
