Mokhahlelo oa bolt o entsoe ka likarolo tse peli tsa linomoro, tse emelang matla a tensile a boleng le sekhahla sa lihlahisoa. Mohlala, se boleloang ke li-bolts tse nang le grade ea ts'ebetso ea 4.6 ke: palo e karolong ea pele (4 ho 4.6) ke 1/100 ea matla a tensile tensile (n / mm2) ea bolt material, ke hore, Fu ≥ 400N / limilimithara2; Palo karolong ea bobeli (6 ho 4.6) ke makhetlo a 10 a karolelano ea lihlahisoa tsa bolt, ke hore, FY / Fu = 0.6; Sehlahisoa sa linomoro tse peli (4) × 6 = "24") ke 1/10 ea ntlha ea lebitso la lihlahisoa (kapa matla a kuno) (n / mm2) ea thepa ea bolt, ke hore, FY ≥ 240n / mm2.

Ho latela ho nepahala ha tlhahiso, li-bolts tse tloaelehileng tsa sebopeho sa tšepe li ka aroloa ka mekhahlelo e meraro: A, B le CA Kereiti ea B e hloekisitsoe bolt, eo hangata e sebelisetsoang lihlahisoa tsa mochini, mme grade C ke bolt e thata. Ntle le ha ho boletsoe ka hosele, li-bolts tse tloaelehileng tsa sebopeho sa tšepe hangata ke li-bolts tse tloaelehileng tsa boemo ba C tse nang le grade ea ts'ebetso ea 4.6 kapa 4.8.
