I'd wish they would focus more on selling screws in bigger containers (with appropriate price discount). Also work to get them certified as replacement for nails in building code.
I prefer GRK over Spax but sometimes Spax are just easier to find.
My most used GRK is the R4 #9 x 3 1/8" and the #9 x 2 1/2". They are available in boxes of 2000 pieces at real lumber yards. [smile]
I haven't used a lag bolt in years since the release of the RSS version. I've installed everything from wall mounted vanities to stainless railings with the RSS. Fantastic fastener.

I use GRK's trim head screws in 305 stainless for exterior cedar trim.
Here's a list of code approvals

My problem with using number 1 Systainers is how many would it take to hold 3 parachute bags of GRK fasteners and 1 parachute bag of Spax fasteners?
