Tá grád cruinnis an tsraith GLR (scriú liathróid cnó amháin le snáithe méadrach) bunaithe ar C5, CT7 agus CT10 (JIS B 1192-3). De réir grád cruinnis, súgradh aiseach 0.005 (réamhualach: C5), 0.02 (CT7) agus 0.05mm nó níos lú (CT10).
Sraith GLR (scriú liathróid cnó amháin le snáithe méadrach) d'ábhar scriú seafta scriú S55C (cruachan ionduchtaithe), ábhar cnó SCM415H (carburizing agus cruachan), is é cruas dromchla an chuid scriú liathróid ná HRC58 nó níos airde.
Rinneadh caighdeánú ar chruth deireadh na sraithe den tsraith GLR (scriú liathróid cnó amháin le snáithe méadrach). Is féidir slat scriú agus cnó a ordú ar leithligh.
