Buying guide
Applies to all chipboard screws.
Drive type
Pozi drive is standard in Europe. Star (Torx) drive transmits more torque with less cam-out and is preferred for long timber screws.
Full or partial thread
Partial thread pulls two boards together; full thread is for fixing hardware and fittings into a single board.
Type 17 point
A notched cutting point starts quickly near board edges and reduces splitting, which matters for decking and framing.

Questions about this product
What is the difference between chipboard and wood screws?
Chipboard screws have a thinner core and sharper, deeper thread, so they hold better in particleboard and need no pilot hole in most softwoods.
Which finishes are available?
Yellow zinc, white or blue-white zinc, black phosphate, nickel and ceramic coatings up to 1,000 h salt spray.
Can you pack in retail boxes?
Yes, we pack in small boxes, buckets or bulk cartons with your labels and barcodes.
