Common questions

Who makes Proto tools?

Proto is the industrial hand tool line of Stanley Black & Decker. Every listing here names Stanley Black & Decker as the manufacturer and carries the Proto manufacturer part number you would order against.

Is the country of origin listed for each Proto tool?

Yes. Every listing publishes country of origin in its specification table alongside the manufacturer part number and UPC, so it can be checked before ordering rather than after. Origin varies by part number — it is not the same across the line.

What is the difference between a 6-point and a 12-point socket?

A 6-point socket contacts the flats of a fastener across a wider face, so it grips harder and is less likely to round a tight or corroded nut. A 12-point engages every 30 degrees instead of every 60, so it is faster to seat in a confined space. Both are stocked here.

When do you need an impact socket rather than a chrome socket?

Use an impact socket on any powered impact wrench. Impact sockets are made from a softer, more ductile alloy with thicker walls so they deform rather than shatter under sudden torque; a chrome hand socket can fracture. Impact sockets here are finished in black oxide.

What drive sizes does Proto make?

The sockets and drive tools on this page run 1/4, 3/8, 1/2, 3/4 and 1 in. drive. Drive size is the square that mates with the ratchet, and it is a separate specification from the socket size that fits the fastener.

Do the listings show which standard a tool is built to?

Where Proto publishes a standard for a part, it is reproduced in that listing's specification table — for example the J07500-10 impact socket set is listed against ASME B107.110-2012. That figure comes from the manufacturer's own published data, not from us.

What is in the Lab Tool Kit?

Twelve items assembled by LabSupplies.com: ten Proto hand tools — an open tote, a 3/8 in. drive socket set and ratchet, an adjustable wrench, slip joint pliers, an 11-in-1 driver, a precision screwdriver set, hex keys, a ball pein hammer and an aligning pry bar — plus HexArmor cut-resistant gloves and goggles, because Proto does not make protective equipment. It is not a Proto-branded kit, and every component is listed with its own part number.

Proto is the industrial hand tool line of Stanley Black & Decker. Every item is listed under its Proto manufacturer part number, and the specifications shown here are taken from that part number. Filters cover the attributes Proto publishes for each category, so the available filters differ between categories.
