Heavy Duty Large Allen Key Hex Set 32mm 27mm 26mm 24mm 22mm 3/4 Metric
Wera Hex plus Allen keys
Heavy Duty Large Allen Key Hex Set 32mm 27mm 26mm 24mm 22mm 3/4 Metric. Also is one with USA on it and a 10 but it is a tiny bit smaller than the 27 so I assume it is a 26mm, and also is one that is marked 3/4 USA.
