Class 3 Chipboard Screws Csk Ribbed 1000 Pack

The Class 3 chipboard screw is a quality fastener for very soft timbers, MDF and particleboard. An aggressive coarse thread and a thin shank let the screw bite firmly into soft base materials and minimise strip-out, while the aggressive ribbed countersunk head (6 nib) eases countersinking for a clean flush finish. Available in zinc and galvanised finishes, the screw suits furniture construction, cabinet making, office partitioning and formwork.

Frequently Asked Questions

Why is a Class 3 screw good for soft timbers?

The aggressive coarse thread and thin shank are designed to bite firmly into very soft timbers, MDF and particleboard while minimising strip-out, which is the common failure with a fine-thread screw in these materials.

What does the 6 nib ribbed head do?

The ribs under the countersunk head act as a countersink cutter, opening the surface as the screw seats so the head pulls flush without a separate countersinking step.

What finishes are available?

The screw is available in zinc and galvanised finishes, so you can match the corrosion protection to where the piece will live. Interior furniture and cabinetry are well served by the zinc finish.

What is the difference from the 8-9 gauge chipboard screw?

The 8-9 gauge screw is a heavier, longer chipboard screw for thicker board, while the Class 3 range covers the standard soft-timber chipboard sizes in a 1000 pack.
