Channellock 12-Inch Tongue & Groove Plier 440 — Straight Jaw, High Carbon Steel, Made in USA

Premium performance you can rely on

The 12-inch Channellock Tongue & Groove Plier 440 blends forged high-carbon steel with precision engineering to deliver a secure, long-lasting grip. Laser-heat-treated 90° teeth and a straight jaw profile are designed to bite firmly in multiple directions, helping you tackle stubborn fasteners, pipes, and hardware with confidence. The tool is crafted with a patented undercut tongue-and-groove action to minimize jaw slip, so you can work more efficiently and with less interruption.

Key build details include a robust PERMALOCK fastener that reduces nut and bolt failures, reinforced edging to withstand heavy use, and CHANNELLOCK BLUE comfort grips for ergonomic handling during extended sessions. The combination of durability and thoughtful design aims to support both professional applications and serious DIY projects, without promising guaranteed outcomes—only possibilities based on the tool’s features.
