Sgriubha:
Is e seòrsa de fastener a th ’ann an sgriubha, ann an cuid de dhòighean coltach ri bolt, mar as trice air a dhèanamh de mheatailt, agus air a chomharrachadh le druim helical, ris an canar snàithlean fireann (snàithlean taobh a-muigh). Bidh sgriothan air an cleachdadh gus stuthan a cheangal le bhith a ’cladhach a-steach agus a’ ceangal a-steach do stuth nuair a thèid a thionndadh, fhad ‘s a bhios an snàithlean a’ gearradh claisean anns an stuth a tha ceangailte a dh ’fhaodadh cuideachadh le bhith a’ tarraing stuthan ceangailte ri chèile agus a ’cur casg air tarraing a-mach. Tha mòran sgriothan ann airson measgachadh de stuthan; tha an fheadhainn a tha gu tric air an ceangal le sgriothan a ’toirt a-steach fiodh, duilleag meatailt, agus plastaig.
Mar as trice bidh ceann air stiùireadh , le inneal. Tha innealan cumanta airson sgrìoban dràibhidh a ’toirt a-steach screwdrivers agus wrenches. Mar as trice tha an ceann nas motha na corp an sgriubha, a chumas an sgriubha bho bhith air a stiùireadh nas doimhne na fad an sgriubha agus gus uachdar giùlain a .
Sgriubha fiodha:
Chaidh sgriothan fiodha tràth a dhèanamh le làimh, le sreath de fhaidhlichean, chisels, agus innealan gearraidh eile, agus chithear iad sin gu furasta le bhith a ’toirt fa-near farsaingeachd agus cumadh neo-riaghailteach nan snàithleanan, a bharrachd air comharran faidhle air fhàgail air ceann an sgriubha. agus anns an àite eadar snàithleanan. Bha deireadh gruamach aig mòran de na sgrìoban sin, gu tur às aonais a ’phuing biorach biorach air cha mhòr a h-uile sgrìob fiodha ùr-nodha. Mu dheireadh, chaidh lathes a chleachdadh gus sgriothan fiodha a dhèanamh, leis a ’phaitinn as tràithe air a chlàradh ann an 1760 ann an Sasainn. Anns na 1850n chaidh innealan sèididh a leasachadh gus snàithlean nas èideadh agus nas cunbhalaiche a thoirt seachad. Tha sgriothan a chaidh a dhèanamh leis na h-innealan sin air glinn cruinn le snàithleanan biorach is garbh. Chaidh cuid de sgriothan fiodha a dhèanamh le gearradh a ’bàsachadh cho tràth ri deireadh na 1700an (is dòcha eadhon ro 1678 nuair a chaidh susbaint an leabhair fhoillseachadh an toiseach ann am pàirtean).
Aon uair ‘s gu robh innealan tionndaidh sgriubha air an cleachdadh gu cumanta, chaidh a’ mhòr-chuid de sgriothan fiodha a bha rim faighinn gu malairteach a thoirt a-mach leis an dòigh seo. Tha na sgriothan fiodha gearraichte seo an-còmhnaidh air an teip, agus eadhon nuair nach eil an shank le teip follaiseach, faodar an aithneachadh leis nach eil na snàithleanan a ’dol seachad air trast-thomhas an t-shank. Tha e nas fheàrr a leithid de sgriubha a chuir a-steach an dèidh a bhith a ’drileadh toll pìleat le pìos drile le teip. Tha a ’mhòr-chuid de sgriothan fiodha an latha an-diugh, ach a-mhàin an fheadhainn air an dèanamh le umha, air an cruthachadh air innealan roiligeadh snàithlean. Tha trast-thomhas seasmhach aig na sgriubha sin, snàithleanan le trast-thomhas nas motha na an shank, agus tha iad nas làidire leis nach eil am pròiseas rollaidh a ’gearradh gràn a’ mheatailt.
