●The yield point of the rebar steel is the value obtained by multiplying the nominal cross-sectional area by the reference strength of SD345, 345 N/mm².
●The yield strength of the steel for the full-thread bolt is the value obtained by multiplying the base strength of SS400, 235 N/mm², by the effective cross-sectional area.
●Do not use for items with smooth surfaces, such as round bars, which may not exhibit sufficient strength.
●The number of applications per set (pcs) is approximate.
