Secure-Grip Tight-Clearance Offset Sockets


The opening makes more contact with fasteners for a better grip than standard open-end sockets. Also known as flare-nut or line wrench sockets, they're often used with flared tube fittings and fuel and hydraulic lines.
Hex secure-grip sockets achieve the best possible grip on hex fasteners and prevent rounding.
12-point secure-grip sockets quickly position on hex fasteners.

Open-End 6-Point Sockets
![]() | ![]() |
![]() |
Slide the open side of these sockets over a tube or hose to adjust a nut that’s already installed. You can turn them with ratchets, so they’re easier to use than open-end wrench heads—no need to pull the socket off the nut and reposition. The hex shape provides the best possible grip on hex fasteners and prevents rounding. Only use with hand-driven tools.
