Overview

The GEARWRENCH 86910 is a 10 millimeter wrench measuring about 6.67 inches long and weighing 0.13 pounds, sized for reaching fasteners in tight engine bays or equipment panels where a standard-length wrench will not fit.

GearWrench sells this size in both standard and long-pattern combination wrenches, and many carry ratcheting box ends on one side. The listing data confirms the 10mm capacity and length but does not state whether the box end ratchets, so confirm that feature on the product page if it matters.

Who it's for

Suits mechanics and DIYers who need a dedicated 10mm wrench for automotive or equipment work. Not useful on its own for anyone needing a full metric set, since this listing covers a single size.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

Compact 6.67 inch length fits tight clearance areas
Light at 0.13 pounds for easy handling

What to check first

Single 10mm size only, not a set
Shorter length gives less leverage than a full-size wrench

Performance notes

At 6.67 inches, the wrench is on the shorter side for a combination wrench, giving more clearance in cramped spaces at some cost to the leverage a longer handle would provide on a stuck 10mm fastener.
