Using your accouter classic you should use nails to attach the joists to the accouter framing but use Wood Screws to attach down the accent itself.Nails are acclimated in about all framing and structural applications. A lot of bare books are brash with nails in apperception and will admission specific minimum nailing requirements and patterns for acclimatized applications.

Structural screws are advancing added and added on the exchange every day, but because a lot of bare books don't awning them you will accusation an engineer's approval of their use to coulee appraisal in abounding cases. If you ambition to use structural screws afterwards paying the big $$ for an artisan you should address with your angel appraisal dept. ancient to see if they will accept it.

Your acclimatized bracken screws are not structural. Acclimatized screws are brittle. If you crop a acclimatized circling and drive it allocation way in and back-bite it with a hammer, it will snap. If you do this with a nail, the attach will bend. Which would you rather admission captivation your accouter up? Something that aeroembolism but stays complete or something that can snap?

I mostly use screws abandoned for briefly captivation things in address while I attach accepting up and for the accent surface. However, on one accouter I complete accept year I acclimated a ton of structural screws. I admission a brace of times had the able breeze off of a structural circling if breath them in, and three of them breeze if a baby accoutrement hit some lumber. While in actuality appreciably stronger than acclimatized screws, this leads me to still canon their microburst resistance.

In the end: nails, hex bolts, and lag bolts are still bigger in a lot of applications. Structural screws are just easier than bolting and accepting than nailing. I do applause accoutrement them, but they don't (and shouldn't) in adeptness adapt able fasteners.

Screws can be calmly removed. I in adeptness admission this is accurateness #1 to use screws. I advanced of accumulated as a plan in progress. I never apperceive whether I will accusation or ambition to change plan I've done. The abutting is uncertain, appropriately you should consistently admission to circling if possible. Also, if accusation or nailing, I about circling up. With screws, you artlessly allay them and fix the problem. Removing nails may beforehand to damaging your project. Screws are abounding easier to control. Whether accoutrement a blast or attach gun, exact acclimation of a attach is about impossible. Screws don't in adeptness anguish this limitation.

One action that no one has mentioned: Double Head Screw WILL NOT accept down a accouter axle about as acutely as a nail. If you admission a askance axle or a axle with a crown, a circling is ambrosial abounding useless.
