TEKTON 1/2 in. Drive x 23 mm Deep 12-Point Impact Socket SID23323 - The Home Depot

Classically lean and quietly refined, TEKTON Combination Wrenches provide a sure fit on fasteners and multiple options for working around obstructions or in tight spaces. To reduce the working swing arc, the open end is angled 15° so the wrench can be flipped over with each rotation to engage the fastener twice as often. The 12-point box end doubles the access angles of a 6-point. It's offset 15°, creating clearance for your fingers and extra space to slide past whatever might be in the way. To prevent round-off, it contacts and applies force to the flat sides of fastener heads rather than the corners
