Tight-Clearance Ratchet Wrenches

Rather than teeth, these wrenches use a series of rollers to engage the ratchet, enabling work in the tightest of spaces. Also known as silent ratchets, they don't make the traditional click sound when turned.

Turn sockets in the most confined spaces.

Nonsparking Ratchet Wrenches

Made of aluminum-bronze, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Electrical-Insulating Ratchet Wrenches

Insulated to protect against accidental contact with live electrical circuits, these wrenches are tested to 1,000 volts to meet IEC 60900.

Replaceable-Head Ratchet Wrenches

When the ratchet head becomes worn or damaged, change it out for a new one.

Fast-Driving Ratchet Wrenches

Twist the grip to rapidly turn a socket before final tightening or to remove a fastener once loosened. The handle also swings like a traditional ratchet wrench.
