I picked up this Snap-On magnetic screwdriver set at a garage sale for $5! I would like to replace some of the damaged and missing bits, and am unsure if all of the bits included are original. Here's what bits are included, in order as on the sticker inside the kit:
Hex bits are stamped CRA2A, CRA2.5A, CRA3A, CRA3.5A, CRA4A. I didn't think these are original, as they are longer and have an O-ring half way up the hex. In the picture, they are outside the box, farthest back. After seeing the catalog scan, I guess they are correct for the set.
I believe the item that looks like a nut in the open box is part of the 1/4 adapter. Unfortunately that's all there is of it if I am right.
Hex bits are marked with an "S" in a box with slanted sides and T-8, 9, 10, 15, 20, 25, 27 and 30. They all also have a mark that looks like a number 3 or a lightning bolt.
Pozidrive bits are marked SDM 252 and 253, followed by a "Z" in a circle, an "R" in a circle. On another facet they are stamped PZ#2 PAT and PZ#3 PAT.
Phillips bits are marked SDM 221, 222 and 223, followed by a "Z" in a circle, an "R" in a circle. On another facet they are stamped PHILLIPS 1, 2 and 3.
Standard bits are marked SDM 211 and 213, followed by a "Z" in a circle, an "R" in a circle.
Seen to the right of the box in the picture are some square drive bits, two marked S-0, four marked S-1 and two marked S-2 with no other markings. Finish and material appear identical to the bits marked with the "SDM" numbers.
Last are two much lighter looking bits, one unmarked phillips and one standard marked only with a "5". I assume these are generic bits used to replace damaged originals.
The driver is marked Snap-On SSDM41 USA.
I did a quick internet search and found the set in a 1983 catalog, but the torx bits are listed with "SDM" numbers like the others I have. Here's a link to the catalog scan http://www.vintagesnapon.com/catalogs/catalogs.php?loggedin=0&catalogPage=5300
Are these bits still available? Individually or as a complete set? Are the torx bits I have made by Snap-On?
