8-9 x 38mm Chipboard Screws Csk Ribbed 1000 Pack

The 8-9 x 38mm chipboard screw is the standard length for everyday chipboard, MDF and softwood assembly. The coarse thread pulls firmly into the board, and the ribbed countersunk head self-embeds to leave a clean flush finish over the surface. Supplied in a 1000 pack, it is the volume size for cabinet shops, joiners and site carpenters who work through fixings quickly.

Frequently Asked Questions

What board thickness does 38mm suit?

At 38mm this screw suits standard 16 to 18mm chipboard and MDF where the screw passes through one board and grips firmly in the one below. For thicker laminated panels, move up to the 51mm length.

Do the ribs really stop the head standing proud?

Yes. The ribs under the countersunk head cut into the surface as the screw seats, so the head pulls flush without needing a separate pilot countersink. That is what gives the clean finish.

Are these the same screw as the 51mm version?

They are the same head and thread design, just a shorter 38mm body. The 51mm pack is for thick board and multi-layer joints; 38mm is the everyday cabinet and joinery length.

Can I use them with a cordless driver?

Yes. The coarse thread and sharp point drive cleanly with a cordless drill driver set to a moderate clutch so the head seats flush without over-driving into the board.
