3/8 in SAE Open End Wrench

This Wiha 20135 open end wrench fits SAE 3/8 in fasteners. It is made from alloy steel with a high visibility coating. The single ended head features a rounded profile and a 10 degree angle. Insulated handles provide protection for electrical work.

Technicians needing insulated hand tools

The insulated design suits electricians and maintenance staff working near live circuits. The single ended format limits use to one fastener size. Buyers requiring multiple sizes or double ended versatility should look at other options.

10 degree single ended head

The 10 degree offset allows access in tight clearances. A rounded head profile reduces fastener rounding. One piece alloy steel construction delivers strength for daily use. This specific head geometry decides if the wrench fits the job.

Questions about this item

Should I choose the 3/8 in open-end wrench or another SAE size?

Select the 3/8 in head when that exact fastener size is required; other SAE sizes fit different bolt heads, so match the wrench to the fastener.

What does the 10-degree offset do when the wrench is in use?

The 10-degree angle lets the open end engage a fastener in tighter swing arcs, reducing the space needed to turn the bolt.

How does the insulated coating affect the tool's electrical safety rating?

The insulated coating is designed to protect against accidental contact with live circuits up to the rated voltage for insulated hand tools.
