7-piece 12-point hex impact socket set

Suits jobs needing 12-point hex engagement

Mechanics who need 12-point contact on hex fasteners will find the right profile here. The 7-piece count covers a specific range without duplicating common sizes already owned. Buyers who need a broader range of sizes or different drive profiles should look at larger or mixed sets.

12-point hex profile on 3/8 inch drive

The defining specification is the 12-point hex geometry combined with a 3/8 inch drive. This pairing determines exactly which fasteners the sockets fit and which ratchets or guns they attach to. Verify that both the fastener shape and the drive size match your application before purchase.

Questions about this item

Will the 12-point sockets need replacement if the corners round off?

The 12-point design distributes torque across more surfaces, reducing corner rounding compared to 6-point sockets, so the set resists wear under normal impact use.

Does the 3/8 inch drive limit the torque I can apply with the 7-piece set?

The 3/8 inch drive is rated for lower torque than 1/2 inch drives, so it will reach its limit first when loosening very large or seized fasteners with the 7 sockets.

Do the impact sockets get hot during all-day use in a shop?

Impact sockets absorb repeated hammer blows without significant heat build-up, and the 12-point geometry spreads force evenly, keeping temperatures low during continuous operation.
