Tus Tsov tus tw ntawm lub laum tail screw yog nyob rau hauv cov duab ntawm ib tug laum tail los yog ib tug taw tes tail. Nws tsis tas yuav tho qhov ntawm lub workpiece ua ntej, thiab tuaj yeem xyaum ncaj qha, kais, thiab xauv rau ntawm qhov chaw thiab cov khoom siv hauv paus. Piv nrog rau cov ntsia hlau zoo tib yam, lub laum tail screw High tenacity thiab tuav lub zog, nws yuav tsis xoob tom qab lub sijhawm ntev ntawm kev sib xyaw ua ke, yooj yim thiab nyab xeeb siv, drilling thiab tapping tuaj yeem ua tiav hauv ib qho haujlwm, txuag lub sijhawm, kev ua haujlwm thiab kev ua haujlwm. Drilling screws feem ntau yog siv los kho cov hlau phaj xws li steel phaj fasteners, feem ntau yog siv los xauv cov hlau phaj thiab cov hlau tsis yog hlau, xws li rau kev kho ncaj qha silicon-calcium boards, gypsum boards thiab ntau yam ntoo boards ntawm cov hlau phaj. Drilling screws nrog tsim tsim nyog thiab cov qauv tuaj yeem ua rau cov phaj hlau thiab cov phaj mating nruj nreem kaw, tsis txhob muaj kev puas tsuaj thiab khawb ntawm cov phaj mating, thiab yooj yim rau nruab.
