Product Description

The GEARWRENCH 86408 is an 8 mm combination wrench built for professional technicians who need a fast, reliable hand tool in tight spaces. The box end features a 12-point ratcheting mechanism, allowing the user to work without removing and repositioning the wrench on the fastener after each stroke. The open end delivers standard flat-sided engagement for quick fastener placement. Constructed from chromium-vanadium steel with a polished finish, this wrench resists corrosion and holds up to repeated use in demanding shop and field environments. Overall length is 5.91 inches with a 0-degree head offset and a head thickness of 0.18 inches.

Installation Notes

This wrench is a hand tool used by trade professionals across HVAC, plumbing, and electrical disciplines. Always confirm the fastener size before applying torque to avoid rounding. When servicing live equipment, de-energize electrical systems per NEC guidelines and isolate refrigerant or fluid circuits before loosening fittings. Keep the wrench clean and inspect for wear or deformation before each use.
