Lag Screw/Bolt question and a cheap place to get em

Postby LeonardPotato » Wed Mar 29, 2017 6:24 am

Burners,

I have been reading the forums and found that most people recommend rebar or lag screws.

I recently purchased mine because I stumbled on a site that was a lot cheaper than anything else I could find. Not being too familiar with lag screw/bolts prior to this endeavor, I was surprised to find out what they were. Is the playa so hard that you can screw something into it? I bought some other tent stakes that are 6-8 inches but from what I am reading those won't do it, is this true?

So, did I make the right move in buying 3/8 hex head 12" lag screw Zink Plated?

If so, checkout wholesalebolts.com. I got 20 of them shipped for $25.

PS - I am in no way affiliated with this company, just wanted to pass along a good find.

The site I posted has 12" in a box of 10 for $5.73. I don't know if the extra 2" are crucial, but shakes out to about the same number per, and I don't need 50 of them.

2" doesn't seem like much, but the top 2-4" of the playa is pretty crumbly and sometimes 14" is *just* enough.
If that's the case, try a small shovel (or stout spoon) and remove the top layer of playa before setting the screw.

Yah, 12" is not always enough. But this particular year, with all the water still heavy on the playa...I'm expecting a good hard packed crust and the stiff mud layer to be even closer to the surface! That means if we get any rain it may not soak into the playa very fast. Bring galoshes!

I'm giving this a nudge over to the Recommendations board, since that's a better fit for threads seeking, offering, or soliciting feedback about stuff to buy.

Those might work, depending on your project. Personally I prefer 14 inch for the conduit frame structures I build. Depending on the playa conditions in a given year, the first several inches of the surface are pretty loose and crunchy.

I am just looking to maintain a tarp structure. It is 16x20 and will be tied to a car, a trailer and have 12 stakes on it. I am hoping it will be a good shade and won't be inclined to take off in those winds.

I will add galoshes to my prep list, thanks!

Thanks for pointing me in the right direct. I will have a look at the 12s and see. Hope what the other guy said about the ground is true.

The larger the tarp, the greater the wind resistance (ie force) pulling on the lag screws. Ground conditions vary widely from year to year. The biggest contributing factor I've found on the depth of the crust is the amount of rainfall the playa gets during the summer months - in a dry summer it could be 8-10 inches of loose pack before you get to harder/wetter stuff, though it averages 4-6 from my experience (before using lag screws I was driving 18 inch hurricane stakes into the ground).

Make sure you have plenty of rope and you should be fine. At the very worst, it's a super dry summer and so you end up needing to dig out a little of the dry crunchy crust to get deep enough with the 12 inch screws. Then you just anchor as usual (rope through one of the links of chain, then tie the guy line off to the top of the structure), and fill back in.

I think it also varies from spot to spot around the playa. I split my build week a few years ago helping build two different camps about 3 hours apart (not something I recommend, by the way), and the hard pack seemed to be down several inches deeper in one than in the other.

12 inchers are a little short (that's what she said) for the playa but like the others said, remove a bit of the top layer before screwing them down and you'll be fine.

Here's your next step...Go to the big box warehouse store of your choice and have them cut 2 to 4 link sections of chain for each lag screw. The head of the bolt should be large enough to hold the chain link so when you screw it in the chain will ll stick out of the dust and you'll have something to hook onto.

I use this system with ratchet straps for my shade structure and it has been bulletproof...so far.

Lag screws are great, but remember to carefully mark the location of each one you put in the ground. They can sometimes get buried during the week and can be easy to forget when packing up!

Good on you for doing your homework! You are doing it right!

PapaBear, I'm confused.

What was 3 hours apart. You mean your break/resting time between appointments? Certainly not the riding time between the two camps. The whole event isn't that big.

3 hours in terms of radial street names. One cap was at 4:30 & E, the other at 7:30 & F (-ish).

Oh. Thanks. I never would have figured that out. I usually head down to 'C' and cut across and back up. It's less tedious. Thanks again.
