Snap-on 10 pc SAE 12-Point Flank Drive Combination Wrench Set, 5/16 to 7/8 in., USA - OEX710
An unbroken ten-wrench SAE run in the original Snap-on tray. Every size present, every wrench stamped USA:
5/16 OEX10B · 3/8 OEX12B · 7/16 OEX14B · 1/2 OEX16B · 9/16 OEX18B · 5/8 OEX20B · 11/16 OEX22B · 3/4 OEX24B · 13/16 OEX26B · 7/8 OEX28B
Flank Drive is why these cost what they do. The box end grips the flats of the fastener instead of the corners, so it turns bolts that are already rounded and it doesn't round the good ones. Twelve-point box ends with Snap-on's 7.5° offset: flip the wrench over and you get a second bite in tight quarters.
Condition. Excellent. Bright chrome across the set, with light handling marks on a couple of the open ends the 7/8 and 13/16 show the most, and they're in the photos. No pitting, no rust, no rounded jaws, no owner stampings. Ships in the original red PAKLD098 tray with its clear cover.
The big sizes are the ones that go missing first. This run is whole.
