Overview
The SUNEX 97329 packs a 29mm jaw capacity into a 3-inch, 13.61-gram body at just $6.99. That combination of a large jaw opening in a genuinely small package explains why 2,291 buyers have rated it 4.6 stars, with around 100 new purchases per month confirming it solves a real, repeating need.
At 13.61 grams, this wrench adds virtually no weight to a tool bag, making it easy to carry as a supplemental tool for a specific fastener that larger wrenches cannot reach in their full arc. The 3-inch overall length limits leverage, so this is not a wrench for breaking loose seized fasteners but rather for tightening and snugging accessible ones.
SUNEX is a professional-grade toolmaker whose product catalog spans sockets, impact tools, and specialty wrenches. The 97329 at $6.99 is priced as an accessible add-on tool rather than a cornerstone purchase, which matches its application profile.

Performance notes
The SUNEX 97329's 3-inch working length and 29mm jaw capacity position it for fasteners that are accessible but not swingable with a standard wrench. Its 13.61-gram weight means zero fatigue concern. The 29mm size commonly appears on brake caliper bolts, axle hardware, and similar automotive fasteners where a compact wrench is the practical choice.
What buyers say
Owners rate the SUNEX 97329 at 4.6 stars across 2,291 reviews, one of the highest-volume ratings in this category. Buyers consistently confirm it fits accurately and holds up to normal use. The primary limitation cited is the inherent torque restriction of a 3-inch wrench, which is a known design tradeoff rather than a quality defect.
The SUNEX 97329 has a published jaw capacity of 29 millimeters, fitting 29mm hex bolts and nuts as found in automotive brake systems, axle components, and other machinery applications.
Can the SUNEX 97329 break loose seized fasteners?
At 3 inches overall length and 13.61 grams, this wrench provides minimal torque leverage. It is best suited for tightening accessible fasteners rather than breaking loose seized ones. For seized 29mm hardware, a longer wrench or a breaker bar and socket would be more effective.
