Bosch Ratchet Set 1600A03AD0, 1/4 and 1/2 inch, 80 pcs

Bosch Ratchet Set 1600A03AD0, 1/4 and 1/2 inch, 80 pcs

The Bosch 1600A03AD0 is an 80-piece set with two drives - 1/4 inch for small fasteners and 1/2 inch for heavy ones - laid out in a case. It is the largest set in the Bosch Professional hand tool range and is meant for the workshop and the service bay, where both fastener sizes turn up in the same job.

The ratchet in the set

The ratchets in this range use a powder-metallurgy ring gear with 72 teeth, giving a 5 degree working angle - that is all the swing needed for the next tooth to engage, and all there is to be had in a tight space. The body is chrome-vanadium steel, the neck is curved and the handle is soft-gripped. The manufacturer states power transfer up to 50% above the requirement of the ISO 3315 standard. The direction switch changes under the thumb, without taking the hand off the tool.

Two drives in one case

The 1/4 and 1/2 inch combination is the classic working pair. The small square carries a short lever and small sockets - the size for panels, boards and clips, where a larger tool simply does not fit and strips threads easily. The large square carries the long neck and the torque needed for anchors, structural bolts and running gear. One case with both sizes saves carrying two sets and hunting for the missing adapter.

Build

The ratchets are chrome-vanadium steel with a powder-metallurgy ring gear and a soft-grip handle. The case holds every piece in its place, so a missing socket shows itself when you open the lid rather than when you need it. The packaging Bosch specifies is a box without a Euro hole.

Applications

Servicing and maintenance of machinery and plant, automotive and agricultural repair, fitting steel structures and anchors, installation work, assembling and dismantling equipment. The set covers most of the usual range of threaded fasteners on a single site without reaching for a second box.

What the manufacturer publishes

For this part number Bosch states a drive size of 1/4 inch + 1/2 inch and 80 pieces. The manufacturer does not publish an itemised list of the individual sockets, extensions and bits for this article, so no such list is reproduced here - the contents can be seen in the official photograph of the case.
