Wood and chipboard screws

Wood and chipboard screws can be screwed in without making a pre-hole. Very sharp and threaded along their entire length, they avoid splitting the wood when screwed in.

Countersunk Head Screws: suitable for fixing wood and plaster, as they allow full insertion into the substrate.

Round-head screws: for better surface contact. This is why they are used to fasten objects.

Chrome-plated brass suet drop screws have a milled round head in the shape of a lens to prevent snagging. More for decorative purposes, they are used to assemble wood that is to be dismantled.
