Tá grád cruinnis na sraithe GLR (scriú liathróid cnó singil le snáithe méadrach) bunaithe ar C5, Ct7 agus Ct10 (JIS B 1192-3). De réir grád cruinnis, súgradh aiseach 0.005 (Réamhluchtú : C5), 0.02 (Ct7) agus 0.05mm nó níos lú (Ct10).
Sraith GLR (scriú liathróid cnó aonair le snáithe méadrach) d'ábhar scriú seafta scriú S55C (cruanú ionduchtúcháin), ábhar cnó SCM415H (carburizing agus hardening), is é cruas dromchla an chuid scriú liathróid HRC58 nó níos airde.
Tá cruth deireadh seafta an tsraith GLR (scriú liathróid cnó aonair le snáithe méadrach) caighdeánaithe.Agus coinníodh é in am ar feadh na bliana. Is féidir slat scriú agus cnó a ordú ar leithligh.
