Self-tapping screws for polycarbonate

Polycarbonate is a modern material used for lightweight structures.

For example, summer-house owners often clad greenhouse walls with it. Neither nails nor rivets are suitable for fastening polycarbonate sheets to metal profiles — special self-tapping screws are needed.

Such self-tapping screws are threaded fasteners with a head, fitted with a cap and a sealing washer. The washer fits snugly against the sheet, ensuring a reliable connection. The cap, shaped as a wide rounded head, ensures a watertight connection, which is important for outdoor structures.

How to use

When installing, a hole is first drilled in the metal profile and the polycarbonate sheet. The hole diameter should be about 1 millimeter smaller than the self-tapping screw’s diameter — only under this condition will the connection be reliable.

The self-tapping screw is then driven in with a screwdriver drill or a screwdriver. Fasteners can have different head types — for Phillips or slotted screwdrivers, raised or countersunk.
