nails for double shearing joist hangers
 
I'm out of galvanized nails, and I'm wondering if I can use 10D brights instead of galv. nails for double shearing the hangers?
I'm out of galv. but I DO have a 5lb box of the brights..... 10D, 3", just not galvanized.

Am I going to be ok or do I have to wait and get more galv.? They are not attaching to PT lumber anywhere.

Thanks!

you cannot do this. It is the shear strength of the nails not the galvanizing that makes a hanger nail so different. Brights are not strong enough for hangers.

Yeah, softer steel.... thought so.
But it's OK, the wife had to go into town anyways after all, so she's getting a 5LB box as we type. Po)

I believe “bright” is the finish of the nail before the galvanizing coating is added. Common is the key word. If you substitute box nails, then you have a problem as the shank size is smaller though the length is equal. It is the length and diameter of the nail that is important for Simpson hangers, you may need to take a reduction of loads and up-lift with other substitutions: http://www.strongtie.com/products/connectors/nails.asp


Don't let her know the trip was in vain.........


Be safe, Gary

Well, the BOX says COMMON, so I think I'm OK?
And Thank You for the link to the nail chart.

I'm hanging 2x12s blocked in the middles and using simpson hangers. I can't imagine trying to use 16 commons in those holes on the sides, they're tight enough with the 10s!

"Well, the BOX says COMMON, so I think I'm OK?" ------ if Common are specified you are fine. Most of Simpson hangers require Common, never box (a smaller diameter).

"I'm hanging 2x12s blocked in the middles and using simpson hangers. I can't imagine trying to use 16 commons in those holes on the sides, they're tight enough with the 10s!" -------- If blocking, why hangers? Or hangers on the ends of the joists, OK!

Be safe, Gary

Yup, hangers on the ends, 2x12 blocking in the middles, as per engineer's plans.
I'm still wondering though, the brights are made in USA, and the galv. are from Taiwanaland, so I'm betting the brights would still be stronger! LOL
But I'm using the required, so all's ..."well"? Po) Thanks Gary.
