Rated 5 out of 5 by from Great for fencing We use these for attaching rails in the pastures. Very strong, long lasting and the head doesn't strip easily compared to robertson heads.

Rated 4 out of 5 by from Great and strong hold, but be careful These work great, I was even able to sink them. Be careful when drilling in close the the edge, they will split the wood, even though they claim to be self tapping. Also, if you need to remove one, best to drill into a fresh hole. I was drilling into end grain, and had to remove a few, when I drove them in again, when they bottomed out, they just started to spin, I couldn't sink them anymore.

Rated 5 out of 5 by from Great replacement for lag bolts Recently used a couple of different sizes of these while rebuilding one of my decks. The existing ledger board was still in good condition but the previous owner had only used nails to secure it to the wall. These bolts sucked it right tight to the structure of the house. Screwed them in using just my Dewalt 18v cordless drill.

Rated 5 out of 5 by from Great product These are my favourite fasteners to use. Really strong, the head is a lot more difficult to strip then a red Robby! I’d highly recommend getting an impact bit with it, as it only comes with a tiny bit to put in a holder

Can these be used on lvl lumber to laminate a support beam

Asked by: Eddie
GRK RSS Fasteners are suitable in ledger board applications, depending on the general rules and spacing details As for the specified application, what is the 2x10” ledger board being attached to and what is its thickness? This will help determine the most appropriate length.
