De réir cruas sreang scriú, ag iompar teannas, neart toraidh agus mar sin de, tá aicmiú grád de bolt soicéad Heicseagán, is é sin, leibhéal bolt soicéad heicseagán. Tá gá le gráid éagsúla de boltaí soicéad heicsidheachúlach a fhreagraíonn dóibh i dtáirgí agus ábhair éagsúla. Tá na gráid seo a leanas ag gach bolt soicéad heicsidheachúlach:
Roinntear boltaí soicéad heicseagán i boltaí gnáth-neart agus ard-neart de réir neart grád. Tagraíonn gnáth-boltaí soicéad heicsidheachúlach d'aicme 4.8, tagraíonn boltaí soicéad heicsidheachúlach ard-neart d'aicme 8.8 nó níos airde, lena n-áirítear rang 10.9 agus rang 12.9. Go ginearálta is scriúnna ceann cupán soicéad HEX dubh iad boltaí soicéad heics de ghrád 12.9 le knurling, dath nádúrtha agus ola.
Is é grád feidhmíochta na boltaí soicéad heicsidheachúlach le haghaidh nasc struchtúr cruach ná 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Tá níos mó ná 10 grád, ina measc déantar na boltaí de ghrád 8.8 agus níos airde. déanta as cruach cóimhiotail ísealcharbóin nó cruach mheáncharbóin agus teaschóireáilte (múchadh, tempered), ar a dtugtar go ginearálta boltaí ard-neart, agus is gnách go dtugtar boltaí gnáth ar na cinn eile. Tá an lipéad grád feidhmíochta bolt comhdhéanta de dhá chuid, a léiríonn faoi seach an luach neart teanntachta ainmniúil agus cóimheas buckling an ábhair bolt.
