Overview
At about 2 inches long and roughly 13.6 grams, the SUNEX 5303 is sized as a small, single-piece wrench rather than anything full-length, intended for a narrow, specific fastening task.
At just over half an ounce and 2 inches long, this is a small specialty wrench rather than a standard combination or adjustable wrench; no drive size, fastener size, or material spec came through in the listing, so confirm fit against your specific application before buying.

Who it's for
