3/8" 12-Point Insulated Wrench
The Gray Tools 160B-I is a combination wrench built for electrical work where live circuits up to 1000 V may be present. It suits electricians and maintenance technicians who require individually tested hand tools for high-voltage environments.
Capacity and headroom
The wrench fits 3/8" fasteners with a 12-point drive that engages from multiple angles. Dual-layer insulation uses an orange outer layer over a yellow inner layer that acts as a visual wear indicator; once yellow shows, the tool must be replaced. Testing follows ASTM F1505 standards for 1000 V protection.
Build quality and daily use
The insulated coating adds bulk compared to standard wrenches, so access in tight panels may be limited. The colour-change safety layer lets you confirm integrity at a glance before each job. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm.

Questions about this item
Will the 3/8" 12-point 1000V insulated wrench fit the same fasteners as my existing non-insulated 3/8" 12-point wrenches?
Yes, the 3/8" hex size and 12-point drive match standard 3/8" 12-point fasteners, so it engages the same bolt heads you already work with.
How can I verify the insulation is still intact after each use?
The wrench has an orange top insulation layer over a yellow inner layer; if the yellow layer becomes visible, the insulation is compromised and the tool must be removed from service.
Does the wrench come with a storage case or any accessories, or is it sold individually?
The product is supplied as a single insulated combination wrench; no case, pouch or additional accessories are included in the box.
