Frequently Asked Questions

What sizes are included in the J1200FASD set?

The J1200FASD is a 15-piece fractional (SAE) set spanning 5/16 through 1 1/4 inch. Ace Tool lists the individual openings from 5/16, 3/8, and 7/16 inch through 1 1/4 inch, so it is intended for inch fasteners rather than metric sizes.

What fasteners can the 12-point box ends fit?

The 12-point box ends are specified to fit 4-, 6-, and 12-point fasteners. The 12-point layout also permits fine indexing, which can help when access is limited and the wrench must be repositioned in smaller increments.

Do all open ends have Proto's ASD anti-slip design?

No. Proto's ASD anti-slip open-end design is not applied to fractional sizes 11/32 inch and smaller. In this 15-piece set, the 5/16-inch wrench is the listed small-size exception; the larger listed pieces carry the ASD designation in Ace Tool's included-wrench list.

What storage and construction details are listed?

The set is supplied with a J25TR34C textile tool roll with 15 pockets, one for each wrench. The listed construction is forged alloy steel with a satin finish, and the set weight is 9.75 pounds. FastoolNow likewise identifies the material as forged alloy steel and the included accessory as a tool roll.

What specification is listed for the J1200FASD?

Ace Tool lists ASME B107.100 as the specification for the J1200FASD. That is a product specification for this exact 15-piece set, rather than a general statement about Proto's wider wrench range.
