The Ampco Safety IM-21 Basic Insulated Tool Kit is a compact 9-piece set designed for electrical maintenance work in hazardous environments. Every tool is manufactured from Ampco's beryllium copper alloy — non-sparking, non-magnetic, and corrosion resistant — and individually insulated to 1,000V for protection against accidental contact with energized conductors. The kit covers core hand tool needs: adjustable combination and groove joint pliers, lineman's side-cutting pliers, Phillips and standard screwdrivers, an adjustable wrench, two single box-end wrenches, and a scratch brush, all stored in a tool box with removable tray. A leaner alternative to the IM-20 for applications where a full socket set is not required. Made in the USA.

Frequently Asked Questions

Is the entire kit rated to 1,000V?

With one exception, all tools in the IM-21 kit are individually insulated and rated to 1,000V AC/DC — the adjustable wrench is not 1,000V rated. For live electrical work where every tool in contact with the circuit must be fully rated, confirm the specific tool requirements for your application before use.

What is the difference between the IM-21 and the IM-20?

The IM-21 is Ampco's basic insulated kit (9 pieces, 7.5 lbs), while the IM-20 is the deluxe kit (17 pieces, 11 lbs). The IM-20 adds diagonal cutting pliers, a 10" adjustable wrench, a full 3/8" drive socket set with ratchet and extension, and a third box-end wrench. The IM-21 is the right choice when a compact, lighter kit covering core plier, screwdriver, and wrench needs is sufficient.

Can I choose which size box-end wrenches are included?

Yes. The IM-21 includes two single box-end wrenches, and each can be specified as 7/16", 1/2", or 9/16" at the time of order. Select the two sizes that best match your most common fastener requirements.

What makes these tools safe for use around flammable atmospheres?

Every tool in the IM-21 kit is manufactured from Ampco beryllium copper (BeCu) alloy, which does not produce friction sparks when struck against hard surfaces. This makes the kit appropriate for maintenance work in oil and gas, petrochemical, and other classified hazardous locations where both ignition risk and electrical shock hazard are present simultaneously.
