Simpson Strong-Tie S13A250SNC 304SS 15° coil ring shank nails 2-1/2"

I bought these nails and used all of them last summer doing a hardie lap siding job. I bought 2.5" because i was going through hardie, 3/8 inch plywood furring strips, then 3/4" sheathing then hitting studs. I found they bent way too easily. Thought it might be my freeman nailer but when i bought the 2.5" bosch .099 galv. nails i found they were extremely strong. I could nail over another nail and it would just find its path around and not bend or jam. With these SS nails I had a jam probably every 10-20 nails on average

Excellent nails I use in my Bostitch coil nail gun for fastening half log siding to my house. Every 16 inches, the stud gets 2 nails - one through the top of the log and one through the bottom - both at an angle due to the round shape of the siding. Stainless steel is definitely worth the extra cost when doing something so permanent and long term as attaching siding.

Worked great on Hardie Siding. Good price.

Used with Hitachi siding nailer. Good Nail with Good Grab

It does the job, but many double nails problems (2 nails thatr come out at once). Still when looking at the price, I would recommend it. I would buy it again.
