Insulated Open-End Wrench 5/16

This 5/16-inch open-end wrench is built for electricians and maintenance technicians who work on live circuits up to 1000 V. The tool meets ASTM F1505 insulation standards and carries California Proposition 65 notices for chemical exposure awareness.

Fits Standard Fasteners and Safety Protocols

The precision-machined jaw engages 5/16-inch hex fasteners securely, reducing the risk of rounding. Dual-layer insulation with an orange outer layer and a yellow inner indicator layer allows quick visual verification of insulation integrity before each use.

Tested for 1000 V Protection

Each wrench is individually tested to withstand 1000 V, providing reliable dielectric protection during electrical work. The hand-tool format adds no electrical load, generates no heat, and operates silently, leaving the user to focus on the task without added thermal or noise concerns.

Questions about this item

What is the maximum voltage this wrench is rated for during continuous use?

The wrench is individually insulated and tested to protect the user for up to 1000 V.

How hot does the insulation get when the tool is used all day near live circuits?

The orange top layer and yellow safety-indicator layer are non-conductive insulation; they do not generate heat during normal hand-tool operation.

Which safety standard must my tool kit already meet for this wrench to comply?

Each wrench is tested to ASTM F1505, so your insulated tool programme should reference that same standard.
