SD Strong-Drive screws

[JStructsteel]

Besides the screws from Simpson, is there a "Generic" version that is acceptable? I know Simpson wont suggest any, but is there a compariable screw that is cheaper? Asking for a contractor that now realized he messed up going to face mount hangers instead of top mount.

Yes, nails.

I imagine that “acceptable,” in this case, means any alternative fastener that meets or exceeds the ESR-published lateral strengths, withdrawal strengths, and geometric limitations, including fastener head size and spacing requirements.

Never had to entertain a substitution, so I got nothin’.

I imagine the hanger will work fine capacity-wise with either SD screws of nails. Nails can go in pretty fast with a palm nailer or a nail gun specific to this operation.

Is this where people are trying to save $50 on jobs now?

But XR makes a good point about nails. Look in the front of the catalog and see what nails you can use for those hangers to satisfy the loading.

I'm sure people install dollar store screws here and there, but I'd never specify anything else besides what the Simpson book requires.

Spend $200 on the engineer to save $50

Contractor said the hanger needs 26 screws per hanger, and there are 62 hangers. Said a box of 25 was 20$+/-

I looked into the hanger hes talking about, its spec'd by the truss supplier, so I am off the hook., even though at the start I suggested top mount hangers.

Hes looking for a generic version.

Im done with residential after this cat.

I never look at the truss hangers, but do any of them even require screws to get full loading? And do they really need to get full loading from a truss reaction? House contractors will do anything to save $.50

I looked a bit, the one spec'd is 20 or 26 screws/nails depending on load.

This a contractor that wants to change all 2x beams to LVL to be consistent, then put each side of the column, screw them in, and then face mount the joist to one side and call it good.

Thankfully I will never work with this guy again. One-off project.

The good news is there are many potential projects for you to fix from this guy's previous jobs. Good for business.

Yea, and then a fix for the fix.
Im 100% sure nothing ever gets built close to the plans I put out.

While I agree with the comments above concerning silly ways to save a few bucks, 25 screws for $20 is really expensive. I'll bet the contractor priced the wrong screws. I've used SD screws on many projects of my own and while they weren't cheap, they were nowhere near that price. What Simpson connector is this?

Yeah usually outdoor screws are $1 a piece. You can get the regular SDS screws for $.50 a piece or less at Home Cheapo.

 

[XR250]

I think a box of SD screws for hangers is like $10

Most typical top flange hangers do not have that much capacity. The ones that do require a bunch of fasteners - probably not much different than their face-mount counterparts.

That makes a lot more sense.

All this commotion because the builder failed to price the correct screw, lol. Really sums up this profession sometimes.

It's why engineering judgement is so hard to quantify to an average person. Almost any bozo can build houses and there's a really good chance no matter what they do or cheap out on it will never become a real issue. This clown could use thumbtacks in these hangers and it may hold up forever. Well, until it doesn't. And it's our job to figure out which element "it" is and how much care and thought needs to be put into it's design and installation.

I work with a lot of contractors who would take offense to this comment and attribute it to "just another arrogant engineer", who hates to go to the jobsite, doesn't know what he/she is looking at when they get there and provides woefully inadequate details to describe how they want it done. I've read a lot of your posts and I would not put you in that category, but, myself, I appreciate and admire some of the workmanship I see on the projects I observe and I don't mind telling the contractor so. I look at it from the perspective that I cannot build anything. "All" I can do is provide a structural design that is safe and code compliant. Hopefully, my designs have become more constructable over the years, mainly by gathering data I get from the jobsites. Most roof framers know more about geometry than engineers. Crane operators know a LOT more about physics than graduating engineers. It would help if more engineers would put themselves in the contractor's shoes once in a while.
