Fits shop or garage use needing a matched multi-piece wrench set from SUNEX. Not for buyers who need individual wrench sizes confirmed before purchase, since sizing is not broken out here.
Pros and cons

- Individual wrench sizes not broken out in the listing
- No purchases recorded in the tracked month
Performance notes
As an 8 piece set, the value here comes from having a matched range of sizes on hand rather than any single wrench's spec. The listing does not break out individual lengths or opening sizes, so fit for a specific bolt or fitting should be checked against SUNEX's own size chart.
