Is it worth even screwing these brackets in with these screws?

[Jeff543]

I have a cabinet and I've glued the problem-dowels up in the drawer and i want to put brackets in each corner inside.

This is the cabinet and the measurements are 18mm front x 18mm side.

I have 25mm brackets and i have some 3.5mm x 8mm self-tapping countersunk screws.

Will it be ok to use these screws for these brackets, they look tiny but i don't want to crack the wood with big screws.

Thanks.

If you don't want to split the wood, prepilot it. Wood screws are far better at this sort of task and on 18mm thick material with a 1.5mm bracket you should be able to use a 3.5 x 12mm screw or even a 3.5 x 16mm one with care. Pilot size for these is around 2.5 to 2.7mm

Thanks, what if i use the screws the size i'm holding in the photo?

The screws you have look more like self tappers for sheet metal rather than wood?
That said if its chipboard then I've found special chipboard screws are a lot better than normal wood ones.

Ok thanks but are they actually big enough to hold the brackets in?

No, or rather yes, but not for long.

Self tappers may look like wood screws, but the threads are blunter and nowhere near as deep as the threads in wood screws so they are more likely to "choke" as you screw them in (greater chance of breaking out material) and will not hold as well (because the depth of thread is less). In other words they are designed for metals and certain plastics, not wood - and that's why joiners don't use them.

It is a fairly common misconception that all screws are equal when they are clearly not

I'd recommend that you look on eBay for Hospa screws in the appropriate size. Hospa is a brand much favoured in the kitchen and bedroom trades. 3mm screws have a lot less holding power than 3.5mm ones and also have bigger heads

Alternatively, don't Toolstation or Screwfix sell Reisser or Spax screws of the appropriate size?

SPAX Yellox Pozi Screw 3.5 x 12mm (toolstation.com) At £56? I need 16 screws. It'd be cheaper to get a new second hand cabinet.

My screen shows £3.50 (per pack of 200) from your link...

3.5 x 16 are an extra penny...

Where does £56 come from?

Easy enough mistake to make if you don't deal with fixings every day. We order-in every 2 to 4 days, generally 10k or so loose screws and 15k collated nails and pins at a time, but also some collated screws, bolts, TEK screws, concrete screws, coach screws, resin anchors, etc. Everything comes in boxes of different sizes and sometimes things go awry - which is why it took us 6 months to use up one particular size of screw (the order was for 100 boxes of a given size, I.e. 10 000, not a single box of 100) This project eats stuff, so fixings always get used in the end - eventually

I've got the screws, should I nail a little hole in first before i screw in?

Thanks.
