Self Drilling Hex Screw with Rubber Gasket 5.5 x 2, 200 Pack, EPDM Sealing Washer, Hardened Steel

Hex-Head Fastener with Sealing Washer

The self drilling hex screw drives its own pilot hole through metal sheet and clamps down with a bonded rubber washer. Each pack holds 200 pieces at 5.5 x 2 size. The hex head takes a standard socket or nut driver, and the drill point removes the need for pre-drilling on light-gauge steel.

The hardened steel body carries a plated finish for outdoor exposure. A bonded EPDM gasket sits under the integrated washer and compresses against the panel face. That seal covers the hole edge and limits water ingress at roof and cladding fixings. The hex head spreads clamp load across the washer face rather than the screw shank.

The 5.5mm nominal diameter suits metal panel, roofing sheet and purlin work. Length covers sheet-to-purlin connections where the drill point must pass through both layers. The 200-piece pack covers a small cladding run or a service stock holding. Fixings drive with a powered driver at controlled torque to avoid crushing the gasket.
