\u00a0\u00a0\u00a0 Tha e na bharail cumanta gur e sgriothan a th\u2019 ann am boltaichean a\u2019 toirt iomradh air an aon bhathar-cruaidh ceangail. Ach ged a tha iad a 'coimhead coltach - agus tha feartan co-ionann aca - tha iad nan d\u00e0 luchd-ceangail s\u00f2nraichte le na tagraidhean s\u00f2nraichte aca fh\u00e8in. Mar sin, d\u00e8 an diofar eadar boltaichean agus sgriothan?<\/p>\n
Tha Leabhar-l\u00e0imhe an Inneal a\u2019 m\u00ecneachadh gu bheil boltaichean gan cleachdadh airson cruinneachadh ri nithean gun shn\u00e0thainn, mar as trice le bhith a\u2019 cleachdadh cn\u00f2. An coimeas ri sin, thathas a\u2019 cleachdadh sgriothan gus nithean a chruinneachadh le\u00a0sn\u00e0ithleanan. Seo an rud, ge-t\u00e0: chan eil sn\u00e0ithleanan aig a h-uile n\u00ec anns a bheil sgriothan air an cleachdadh mu thr\u00e0th. Bidh cuid de nithean a\u2019 nochdadh sn\u00e0ithleanan a chaidh a dh\u00e8anamh ro-l\u00e0imh, agus cuid eile a\u2019 cruthachadh an t-sn\u00e0thainn nuair a thathar a\u2019 st\u00e0ladh an sgriubha. Mar sin, is e an eadar-dhealachadh bunaiteach eadar sgriothan agus boltaichean gu bheil a 'chiad fhear air a chleachdadh airson stuthan sn\u00e0thaichte a chruinneachadh, agus an t\u00e8 mu dheireadh air a chleachdadh airson rudan gun leughadh a chruinneachadh. Le sin air a r\u00e0dh, faodaidh sgriothan na sn\u00e0ithleanan aca fh\u00e8in a dh\u00e8anamh tron phr\u00f2iseas st\u00e0laidh.<\/p>\n
Is fhiach a bhith mothachail cuideachd gum feumar sgriothan a thionndadh gus co-chruinneachadh a chruinneachadh, agus faodar boltaichean a cheangal nan \u00e0ite le inneal no bolt carbaid. Mar as trice bithear a\u2019 cleachdadh boltaichean airson alt le bolt a dh\u00e8anamh le bhith a\u2019 cleachdadh cn\u00f2 gus feachd a chuir an s\u00e0s fhad \u2018s a bhios iad a\u2019 cleachdadh an shank mar shocair. Tha seo gu bunaiteach a\u2019 ceangal a\u2019 cho-cheangail an aghaidh feachdan taobh. Agus air sg\u00e0th seo, tha m\u00f2ran boltaichean air shank gun sn\u00e0thainn (ris an canar fad greim); mar sin, gan d\u00e8anamh nas \u00e8ifeachdaiche airson dowels.<\/p>\n
Tha dusanan de dhiofar she\u00f2rsaichean boltaichean ann, cuid dhiubh a\u2019 toirt a-steach boltaichean acair, boltaichean arbhair, boltaichean \u00e0rdachaidh, boltaichean crochaidh, boltaichean hex, boltaichean J, boltaichean lag, boltaichean creige, boltaichean gualainn agus boltaichean U. A bharrachd air an sin, tha boltaichean rim faighinn ann an raon farsaing de stuthan, a\u2019 toirt a-steach st\u00e0ilinn, st\u00e0ilinn gun staoin, umha, umha agus nylon. Tha staitistigean a\u2019 sealltainn, ge-t\u00e0, gu bheil suas ri 90% de na boltaichean uile air an d\u00e8anamh de st\u00e0ilinn, ga fh\u00e0gail mar an roghainn as fhe\u00e0rr le companaidhean saothrachaidh.<\/p>\n
Tha dusanan de dhiofar she\u00f2rsan sgriothan ann cuideachd, cuid dhiubh a\u2019 toirt a-steach sgriothan b\u00f2rd-sgiobalta, sgriothan b\u00f2rd gr\u00e0in, sgriothan deic, sgriothan dr\u00e0ibhidh, sgriothan draibhidh \u00f9ird, sgriothan drywall, sgriothan s\u00f9la, sgriothan dowel, sgriothan fiodha, sgriothan d\u00e0-luath, sgriothan ceann t\u00e8arainteachd agus sgriothan duilleag meatailt. Tha cuid de na cumaidhean cinn eadar-dhealaichte anns a bheil sgriothan rim faighinn a\u2019 toirt a-steach pana, putan, cruinn, balgan-buachair, ugh-chruthach, bulge, c\u00e0ise, fillister agus flanged. Agus mar an co-aoisean bolt, tha sgriothan rim faighinn ann an raon de stuthan.<\/p>\n
\u00c0s deidh dhut seo a leughadh, bu ch\u00f2ir gum biodh tuigse nas fhe\u00e0rr agad air an eadar-dhealachadh eadar sgriothan agus boltaichean.<\/p>","protected":false},"excerpt":{"rendered":"
\u00a0\u00a0\u00a0 It\u2019s a common assumption that bolts are screws refer to the same fastening hardware.
