Screw:

Uzskrūvējamu ir stiprinājuma veids, savā ziņā līdzīgu uz aizbīdņa, parasti izgatavoti no metāla, un kas raksturīga ar spirālveida kores, ko dēvē par  ārējo vītni  (ārējo vītni). Skrūves tiek izmantoti, lai piesprādzēšanu materiāliem, rokot un ieķīlēšanu par materiālu, ja ieslēgts, bet diegu griezumi rievas nostiprinātas materiāla, kas var palīdzēt pull piestiprināti materiālus kopā un novērst izvelkamā. Ir daudzas skrūves dažādiem materiāliem; tie parasti piestiprina ar skrūvēm ietver koka, lokšņu metāla un plastmasas.

Skrūvi parasti ir  galva  vienā galā, kas satur speciāli izveidotā forma, kas ļauj to ieslēgt, vai  brauc ar rīku. Bieži rīki braukšanas skrūvēm ietver skrūvgrieži un uzgriežņu. Galva parasti ir lielāks nekā ķermeņa skrūves, kas notur skrūvi brauc dziļāk nekā garumu skrūves un sniegt  nesošo virsmu

Koka skrūve:

Early kokskrūves veica ar rokām, ar virkni failus, kalti un citiem griezējinstrumentu, un tos var satikt viegli atzīmējot neregulāras atstarpes un formu, pavedieni, kā arī failu zīmes paliekot uz galvas skrūves un apgabalā starp diegiem. Daudzas no šīm skrūvēm bija strupu galu, pilnīgi trūkst asu konusveida punktu uz gandrīz visiem mūsdienu koka skrūvēm. Galu galā, virpas, tika izmantoti, lai ražotu koka skrūves, ar agrāk patentu tiek ierakstīts 1760.gadā Anglijā. 1850. gadā aptīšanas instrumenti tika izstrādāti, lai nodrošinātu vienotāku un konsekventāku pavedienu. Skrūves veikti ar šiem instrumentiem ir noapaļoti ielejas ar asiem un raupja pavedieni. Daži koka skrūves, tika veikti ar griešanas nomirst jau vēlu 1700 (iespējams, pat pirms 1678., kad grāmatas saturu pirmo reizi tika publicēts daļās).

Kad skrūvju pagrieziena mašīnas bija parastā lietošanā, lielākā komerciāli pieejami kokskrūves tika ražoti ar šo metodi. Šie griezums koka skrūves ir gandrīz vienmēr samazināts, un pat tad, kad konusveida kāts nav skaidrs, tos var saskatīt, jo pavedieni nesniedzas pagātnes diametra kāta. Šādas skrūves vislabāk uzstādīti pēc urbšanas izmēģinājuma caurumu ar konusveida urbi. Mūsdienu koka skrūves vairākums, izņemot tos, kas izgatavoti no misiņa, tiek veidoti uz Vītņu velmēšanas mašīnas. Šīs skrūves ir pastāvīga diametrs, pavedienus ar lielāku diametru nekā kāta, un ir spēcīgāka, jo ritošā process nešķērso graudus no metāla.
