I didn't notice until I read your question, but mine came with a plastic sleeve instead of a metal one too.
Unhappy about product
No unfortunately not
yes for 1/8 is standard
Not sure what the dimensions are, but they fit a standard size drill. Hope that helps.
you sure can
I was told it would fit any Dewalt drill
Has no bearing on screw head weather it be metric or imperial so will fit both
It’s for doing drywall. Sets the screw at the perfect depth for mudding
It is a merchandising piece only (meant to illustrate the effectiveness of the magnetic screw holder) and can be discarded after purchase.
