We do not recommend a Zinc coated screw for exterior applications. Check out our HCR-X coating that is High Corrosion Resistant and approved for pressure treated lumber and outdoor applications. Thank you for being a SPAX customer.

Answer

The MULTI Head meant to countersink these SPAX screws is not very compatible with a washer. We would not have a size recommendation. If you need a washer head, check out our wafer head screws which are more suited to this use. This line ranges in size from 1-1/4 length to 3-1/2". Thank you for being a SPAX customer.

SPAX would recommend a #14 for this application. If that will not fit the holes on the hinge, then a minimum of a #10 diameter. Thank you for being a SPAX customer.

I want to use this indoors in wood (not drywall). Do I really not need to pre-drill?

Asked by Andkon December 19, 2019

I would say that these screws will be fine in softer wood without pre-drilling. If I were using these in hardwood, I would drill pilot holes to prevent splitting the wood.

Looking for the ones I previous purchased. They must be able to go into concrete patio without pre drilling. Will these?

Asked by djpkw March 4, 2018

These will not go into concrete. Any acre in concrete must be drilled first

saw these at local HD across from the bargain packs of screws. mounting an infrared light for a security camera outdoors I needed something to drill through siding and wood. the key here is that the light is 3lbs and needs to absolutely not sag (screws not firm in the wood) because it will change the illuminating angle and to fix it might require more holes in my siding or it simply won't work illuminating what it needs to. these screws are actually cheaper per piece than the HD bargain screws and cut through siding and bit into the wood like butter. don't hesitate to buy. these are fantastic!!

Used for drawer fronts - good and bad
We used the Spax #8 1" wood screws to attach drawer fronts to drawers. The good is that you don't have to predrill the drawer fronts. We were skeptical - especially since the fronts are 100% cherry. However, they actually work without drilling the holes with no splitting (yet). However, the combo square drive / phillips drive is a bust. When heavy torque is applied (as in attaching the cherry drawer fronts), the heads consistently stripped out. We went through a lot of screws that ended up being thrown away before we had the fronts attached. If these were available with just a square drive, they probably wouldn't have stripped out. Also, they are pretty expensive if you don't really need their special ability to skip pre-drilling - especially given the weakness of the head. I would only recommend them in special situations.

Square bit works way better than Phillips on this screw, but either work. Screws work like screws should. ;)

Solid fastener with the option of using the far superior Robertson bit (square) instead of the mediocre to downright aggravating philips head. Another winner from Spax

Would love to give the product five stars but Spax has a small quality issue that allows several duds in every package, including the smallest of packages. For typical hardware this would be acceptable, but it becomes concerning with more expensive hardware like this. Often predrilling is still necessary to avoid splitting project materials.

Not as good as I thought
I tried to drive these screws into a pine 2x4 that has been sitting in my basement for 10 years. Not impressed. The square recess in the head of the screw doesn't fit a square drive bit that well, so I had some cam-out when the screw was almost in. The square part of The "square x" does not fit that well. I found better results with the phillips bit. I've used square drive before and they worked fine, the quality on these is iffy. If you're going to use them in hardwood, I would recommend you pre drill.
