Screw sizes. or Lag bolts going smaller too.

I'll never use another lag bolt again when there are structural fasteners available that are stronger and made to much higher standards.

"screwed" by the Chinese bolt manufacturers

"Crown" screws are made in Indianapolis. I stopped in once to try to get something special. You want "How Many?" (LOL)

------------------------------------------------ Think metric standardization.

Nope, not in this case. 5/16 is as close to 8mm as damn is to swearing. 7mm is not a "metric standard" The length mabee - 35mm, vs 1 1/2 at 38mm and 1 5/8 at 41 (plus or minus a few decimals)

Yep. Been quite a few years since I've bought a lag bolt from a Borg.

A structural screw like Spax or GRK, besides being hugely stronger in sheer force, has an added benefit in being easier to drive with a quality cordless drill.

Expensive, but well worth it in strength and labor savings.

These are what I buy if strength matters, and yeah you can get them at the borg. ;~)

And they're not what I call "single drive." Meaning, you can back one out and drive it back in without it breaking off like a lag bolt.

I love Spax. Next time you're there check out FastenMaster, if they're carried in your neck. I used this product on my "Sharn" and they were amazing...

Thanks. I think I have seen them on TOH recently.

"Spax", by any other name...

;)

So SPAX doesn't fill the space on a wheel mounting plate like lags do. I don't need heavy structural, I want to fill the space as much as possible.

I don't want the length, just noticed it was much smaller when compared to an old lag.

And yep, spax are neat when used in the right application.
