So, I build a lot of cabinets… Built-ins, a behind-load of floating shelves, etc. I do a lot of other custom wood stuff, too… But today I am focusing on my upcoming cabinet projects.

I use a lot of pocket hole joinery… I like the Kreg screws, but I’ve used a number of different brands as well, with similar results. Never had any call-backs. But pocket holes don’t work for everything…

I recently had a project and the designer spec’d melamine to save overall costs. I bought the melamine screws and drill bit. I was glad I did. They worked really well and I felt it was a good decision to spend the few extra bucks.

I’ve been building some shop furniture and cabinets and tend to build ‘planer’ for that stuff. Simpler boxes with butt joints, screwed together… I don’t like using drywall screws to assemble stuff like this, I much prefer the SPAX construction screws… They have good coarse threads and a nice flat near the head to help pull the pieces together. I don’t mind the star drive heads. They do tend to strip less than any similar phillips head screws I’ve used.

That being said…. Is there a specific screw you like for plywood? Not for pocket holes, but more butt joints, etc…

I am in the process of really examining how I do business. I am trying to get back to ‘buying ahead’. Basically, I’m trying to plan ahead and get/keep more hardware on hand. I want to stop buying screws and typical consumables at the local hardware store or big box store (if it makes sense to do so, of course) in 1 lb boxes… for each project… I want to start buying in larger quantities, basically. But, while trying to save money, I also want to maintain the easiest, most pleasant work experience for me, as well as maintaining the best quality I can afford to produce.

When I ran the commercial shop, Steve would go to Home Depot and buy a large tub of sheet rock screws. Never had a problem.. you can see the tub of screws sitting on the work bench…I think that would have been between 2003-2010. He decided to retire and I went on to the furniture company..I worked for him 7 years , straight cash…He hated the IRS…

This. 1 1/4 for screwing two 3/4” thick things together. 1 3/4 or 2 1/4 for butt joints, depending.

Square drive is superior to Phillips in absolutely every way.

“Robertson” It’s a Canadian thing. Amazing how hard I had to look when in Idaho last summer to find one for some repair work on my RV! https://mysteriesofcanada.com/ontario/robertson-screw/#:~:text=Robertson%20Screw.%20The%20Robertson%20socket%20head%20screw%20soared,it%20reduced%20product%20damage%20and%20sped%20up%20production.

Confirmat screws can be useful. Takes special equipment to drill for them but you can try out a drill bit

I’ve seen these mentioned before… Didn’t try them at the time. I will this time. Thanks!

Also another screw Ive read of, but not sure I’ve ever tried one. I am willing to learn!

These were what I used for the Melamine project i mentioned in the first post. So, I have the drill bits and drive bits for the smaller size screws. I think I used all of my screws up… Maybe I’ll go pick up a small pack at the hardware store and see how they hold in Baltic Birch Ply?

I would bet that more things are held together using drywall screws, than any other screw, nail, or otherwise. The only exception being for framing 16’s and 8’ s, and roofing nails.

Maybe with the increase of decks as part of most homes, decking screws as a category, but they have so many sub types it’s like just saying screws.

That said, I have had failure with the loved drywall screw, so I like SPAX as a brand, and generally will use something of theirs in the proper line for what it is I am doing.
