Question

Aren't 1-1/2" staples too long for 3/4" hardwood flooring?


The hardwood nailer I got (Numax) takes 15.5 ga 1/2" crown staples. All I was able to find in terms of length is 2" and 1-1/2" (Bostitch).

It appears to me that 1-1/2" staples would be too long for nailing 3/4" hardwood into 3/4" OSB subfloor. Because the part of the hardwood strip the staple would go through seems at most 1/2" diagonally (assuming 45 deg angle) and the OSB part maybe a little less than 1" (same angle assumption).

I would not like tips of staples to protrude on the bottom since there is basement on the other side and lots of wires and pipes, not that I think there is wire affixed anywhere to the subfloor above but I would prefer to not have a rough surface with nail tips.

I tried googling 15 ga 1/2" crown with 1" or 1-1/4" length but there wasn't any.

Can you tell me if my 45 deg angle assumption is incorrect and whether I can safely staple 1-1/2" staples into 3/4" hardwood + 3/4" subfloor?

I wouldn't use 1 1/2" staples. If they blow through, you lose holding power. Since the staple goes in the tongue, it is going through less than 3/4" plus the subfloor.

I understand and that was my concern. However, they don't make my size any shorter than 1-1/2".

Assuming a 45 deg angle, the length of the path would be:

[2 x (3/8)^2] ^ 1/2 + [2 x (3/4)^2] ^ 1/2 = 0.53 + 1.06 = 1.59"

which is a little more than the length of the smallest nail but still not much wiggle room for safety

The "standard" for 3/4" is/used to be (?) 2" cleats. That's what I use, and what is recommended. The idea is to fasten through and into the joists and another between the joists.

That's not a good reason at all. Manufacturers want the fasteners to pock through the underside of the subfloor to verify how well the floor was installed in the event you had a claim. In some cases the 1st 1/4" doesn't do anything, has no gripping power.
