This is the first time I've seen fasteners this small. They look like ones I saw in a JLC article. However, in the article they were not using them for a deck attachment. Even then, they should have washers I believe.

There are two fasteners per bay all the way across. I'm not sure of their shear strength and they sure look like they could use washers to prevent from pulling through.

The last attachment is a ThruLok bulletin but I dont know if these are ThruLok screws on this deck. Anyway, you can see in the bulletin that they should have washers on the outer side.

Have you seen these before? Is this a suitable deck attachment?

Yeah,

There are about half a dozen various screws designed and rated for ledger to house attachment now. Most of them are self-drilling types and I guess it's up to the screw manufacturer whether or not they're supposed to have washers. Absent instructions from the screw manufacturer, you're kind of screwed. I'd probably recommend the buyer find out who built the deck, then contact the contractor to find out who made the screws and then use that information to determine if they'd been installed in accordance with the manufacturer's specs.

Could it be this...

They indicate it's approved for ledger attachment.

Simpson clearly marks the heads, so it's easy to identify if they're correct for the application.

I can't read what's on the heads in the OP's pics.

Every County in Maryland that I'm aware of requires 1/2" bolts. They each have their own permit, inspection procedure (footing, framing, finish, etc.).

It's the prescriptive method, but the AHJ would be hard pressed to explain why he or she would not accept a listed, labeled and rated alternative.

Yes, they're marked. But I wouldn't agree with the clearly part. I've had a hard time seeing the marking when holding one loose in my hands. It's hard to put much of a marking on such a tiny surface.

That, or a brass compression ferrule? About 4 mm?

Speaking of rings, my ex brother in law was working as an HVAC contractor when his foot slipped on the ladder. As he slipped down the ladder trying to catch his grip, somehow his wedding ring got hung up on a part of the ladder and it completely degloved his finger. OUCH!

Finger degloved by ring.

I think you meant "queasy" not weary.

Why was he wearing his ring on his middle finger?

Rings are supposed to hurt a bit, but the general rule is the pain is spread out over 40 or 50 years.

Well, I changed my mind and decided to delete is but it got copied before I could pull it. It was only up for a minute. Sorry.

I guess the point is to be careful when wearing rings on ladders.

I would appreciate it if a moderator could remove the picture links. Or maybe those who copied it could edit their posts.

Wrong hand as well.

If it lasts that long. Ends abruptly, full measure of pain delivered instantly.

Download the Baltimore County deck specs, they state "House band board - use minimum 1/2" carriage stagger bolted 16" or minimum 2 Ledger Locks 16" on center." I think the rest of the Maryland counties are the same but they haven't updated their on-line specs to say that yet. I know I've seen it in Carroll and Anne Arundel.

This is why I've always leased and never bought. Once they get miled up, scratched, dented, and start making noise, You can turn them in for a new one and not take the hit for depreciation

Oh, I'd always thought of that as hail stone damage.

Checked in for the latest on a couple of other counties in Maryland (Howard & Carroll) and their specs for ledger attachment say "For other approved attachment such as LedgerLok: Fastener shall be 7? oc staggered up to 12? joist span, 5? oc over 12?." I believe your picture indicates the need for more fasteners.

Charlie,

What's the live load requirement for decks in our area?
