Professional insulated wrench set

Wiha Tools 20196 provides 13 open end wrenches with metric sizes from 8 mm to 24 mm. The alloy steel construction ensures durability for daily professional use. Urethane insulation protects against electric shock and improves grip in wet conditions.

Urethane insulation benefit

The insulation layer allows safer work on live electrical components up to rated limits. It also delivers a more secure hold when hands or fasteners are wet. This combination reduces slip risk and supports compliance with electrical safety practices.

Electricians and maintenance crews

Suited for professionals who need insulated open end access on metric fasteners. Not suited for buyers who require ring or ratcheting ends, imperial sizes, or a smaller piece count for light occasional use.

Questions about this item

Will the urethane insulation on these wrenches degrade and need replacing?

The urethane insulation is bonded to the alloy steel and is not designed to be replaced; inspect it before each use and retire any wrench with cracked or worn coating.

What stops me from using the 24 mm wrench continuously on high-torque fasteners?

The open-end profile contacts only two flats of the fastener, so rounding risk rises before the alloy steel yields under sustained load.

Do the handles get hot or slippery during all-day electrical work?

Urethane resists heat buildup and stays grippy when wet, so the handles remain comfortable and secure through a full shift.
