Fasteners yog siv los txuas ob lossis ntau qhov chaw (los yog cov khoom siv) rau hauv tag nrho.Lawv tau siv dav hauv ntau lub tshuab, khoom siv, tsheb, nkoj, kev tsheb nqaj hlau, txuas hniav, tsev, cov qauv, cov cuab yeej, cov cuab yeej, tshuaj, cov cuab yeej thiab cov khoom siv.Cov cuab yeej, cov cuab yeej, tshuaj, ntsuas thiab cov khoom siv, thiab lwm yam. Nws yog tus cwj pwm los ntawm ntau yam kev qhia tshwj xeeb, kev siv sib txawv, thiab qib ntawm standardisation, series thiab generalisation, Nws yog yam ntxwv ntawm ntau yam specifications, sib txawv kev siv, thiab qib siab ntawm standardization, serialization thiab generalization.
Covntsia hlauyog ib qho ntawm feem ntau siv fastening qhov chaw, siv lub cev thiab lej cov qauv ntawm beveled ncig rotation thiab kev sib txhuam ntawm cov khoom.Cov ntsiab cai ntawm kev ua lej, ib kauj ruam ntawm cov cuab yeej fastening rau cov khoom thiab cov tshuab.Laum-tail screws yog ib qho kev tsim tshiab hauv xyoo tas los no.yog ib tug ntsia hlau nrog ib tug self-tapping drilled taub hau nyob rau hauv pem hauv ntej ntawm lub ntsia hlau, nws tsis tas yuav tsum tau siv nrog cov txiv ntseej, tseem hu ua nws tus kheej tapping screws, tus Tsov tus tw ntawm laum tail screws Drill-tailed screws yog laum-tailed. los yog taw tes-tailed, yog li lawv tuaj yeem tau drilled, tapped thiab xauv ncaj qha rau hauv cov khoom siv thiab cov khoom siv hauv paus yam tsis muaj qhov drilling qhov hauv lub workpiece ua ntej.Lub laum-tailed ntsia hlau muaj lub zog rub thiab txij nkawm piv rau cov ntsia hlau zoo tib yam, thiab yuav tsis xoob txawm tias tom qab lub sijhawm ntev.Nws yog ib qho yooj yim thiab nyab xeeb siv.Qhov drilling thiab tapping yog ua tiav hauv ib qho kev ua haujlwm, txuag lub sijhawm thiab kev ua haujlwm.Drill-tail screws feem ntau yog siv rau fastening hlau daim hlau xws li steel phaj.Lawv feem ntau yog siv rau kev xauv cov phaj hlau thiab cov phaj tsis yog hlau, xws li silica-calcium daim hlau, gypsum boards thiab ntau yam ntoo daim hlau ncaj nraim rau cov phaj hlau.cov ntawv hlau.Qhov tsim nyog tsim laum-tail screws ua rau cov hlau phaj thiab cov phaj mating kom ruaj khov ua ke, tsis txhob muaj kev puas tsuaj thiab khawb ntawm cov phaj mating, Cov ntsia hlau yooj yim rau nruab.
