Disgrifiad o'r Cynnyrch

Self drilling roofing screws are specially designed screws that are commonly used for roofing applications. These screws are made with a sharp point that allows them to drill through roofing materials such as metal, plastic, or wood without the need for a pre-drilled hole. The screws feature a hex head or a washer head that provides a secure connection between the roofing material and the roof deck.

Mae'r sgriwiau toi hunan-drilio fel arfer yn cael eu gwneud o ddur di-staen neu ddur galfanedig, sy'n rhoi ymwrthedd uchel iddynt i gyrydiad a rhwd. Daw'r sgriwiau mewn gwahanol feintiau a hyd, ac maent wedi'u cynllunio i wrthsefyll y tywydd garw y mae toeau yn agored iddynt.

Un o nodweddion unigryw sgriwiau toi hunan-ddrilio yw eu gallu i greu sêl sy'n dal dŵr o amgylch y twll sgriw. Cyflawnir hyn gan olchwr rwber neu neoprene a osodir o dan ben y sgriw, sy'n selio'r twll ac yn atal dŵr rhag treiddio trwyddo.
