Re: [Tools] I need a Impact driver ?

I have 18 volt cordless, both DeWalt and Ryobi. They both work about equally well.
I did not have a 1/4" impact driver for the longest time. Now it is the first thing that I grab if I need to put in any kind of screws.

Torx screws work the best for really holding boards together.

If only you poor Yanks had Robertson screws...

As for snapping bits; there are impact bits out there - I like the dewalt 'impact ready' series of bits myself...

I never heard of Spax. Still don't know what it is...

Torx is a 6 pointed star drive head. Could be any type of threads.

I got real tired of square drive screws trying to work on trailer houses.
Maybe Robertson screws are different than just regular square...

So how does the drive type figure into the holding power of the threads?

It doesn't really. Just the torx driver stay in the heads better than the phillips drivers and makes sure the screw really gets sunk in.

They never will. You know why? Because we invented them and not an American. So they persist with their little girly man slot and philips.

I used to find square drive screws. Most have switched to Torx because of the high licensing fees for Robertson.

You mean screws with the little inset square for driving? We've got them, I helped put up a bunch of drywall with them.

»en.wikipedia.org/wiki/Robertson_ ··· ewdriver says "P. L. Robertson invented the Robertson screw and screwdriver in 1908 and received patents in 1909 (Canada) and 1911 (U.S. Patent 1,003,657). "

They are available here at many places. Actually they are very common for deck screws. They certainly has some advantages over standard slotted or Phillips head screws because the driver stays in the head much better but they are also inferior to Torx!
