Scriú:

Is scriú cineál ceanglóir, i roinnt bealaí cosúil le bolt, de ghnáth déanta de mhiotal, agus arb é a príomhthréith iomaire helical, ar a dtugtar mar  snáithe fireann  (snáithe seachtracha). Scriúnna a úsáidtear chun fasten ábhair trí digging isteach agus wedging isteach i ábhar nuair a chas, agus na grooves ciorruithe snáithe san ábhar fastened go Bealtaine cúnamh tarraingt ábhair fastened le chéile agus cosc a chur ar tarraingt amach. Tá go leor scriúnna d'éagsúlacht na n-ábhar; iad siúd ceangailte go coitianta ag scriúnna measc adhmad, leathán miotail, agus plaisteach.

Beidh scriú bhfuil de ghnáth  ceann  ar foirceann amháin go bhfuil cruth déanta go speisialta a ligeann sé a bheith iompaithe, nó a  thiomáint , a bhfuil uirlis. I measc uirlisí coiteanna do scriúnna tiomána screwdrivers agus wrenches. Is é an ceann de ghnáth níos mó ná an comhlacht ar an scriú, a choimeádann an scriú féidir í a thiomáint níos doimhne ná an fad an scriú agus a chur ar fáil  dromchla imthaca

Wood Scriú:

Bhí scriúnna adhmad Luath a rinneadh de láimh, le sraith de chomhaid, siséil, agus uirlisí gearradh eile, agus is féidir iad seo a chonaic go héasca ag tabhairt faoi deara an spásáil neamhrialta agus cruth na snáitheanna, chomh maith le marcanna chomhad fágtha ar an ceann an scriú agus sa limistéar idir snáitheanna. Go leor de na scriúnna bhí deireadh blunt, go hiomlán ann an pointe barrchaolaithe géar ar beagnach gach scriúnna adhmad nua-aimseartha. Sa deireadh, baineadh úsáid as deileanna a mhonarú scriúnna adhmad, leis an bpaitinn is luaithe á thaifeadadh i 1760 i Sasana. Le linn na 1850í Forbraíodh uirlisí Swaging chuig snáithe níos aonfhoirmí agus comhsheasmhach a chur ar fáil. tá scriúnna rinneadh leis na huirlisí gleannta chothromú le snáitheanna géar agus garbh. Rinneadh roinnt scriúnna adhmad a rinneadh le bás a ghearradh chomh luath agus is na 1700í déanacha (b'fhéidir fiú roimh 1678 nuair a bhí an t-ábhar leabhar a foilsíodh den chéad uair i gcodanna).

Chomh luath agus bhí meaisíní scriú casadh in úsáid go coitianta, bhí scriúnna adhmad is fáil ar bhonn tráchtála a tháirgtear leis an modh seo. Tá na scriúnna adhmad gearrtha barrchaolaithe beagnach i gcónaí, agus fiú nuair nach bhfuil an shank barrchaolaithe soiléir, is féidir iad a discerned toisc nach bhfuil na snáitheanna a leathnú thar an trastomhas an shank. scriúnna den sórt sin suiteáilte fearr tar éis druileáil poll píolótach le beagán druil barrchaolaithe. An chuid is mó de scriúnna adhmad nua-aimseartha, ach amháin dóibh siúd déanta de phrás, atá déanta ar mheaisíní snáithe rollta. Tá na scriúnna trastomhas tairiseach, snáitheanna le trastomhas níos mó ná an shank, agus go bhfuil siad níos láidre toisc nach bhfuil an próiseas rollta ghearradh ar an grán de na miotail.
