9ST13858 - Lincoln Electric T13858 Thumb Screw Assembly for Wire Feeders

Get Your Feeder Back in Action with the Lincoln T13858 Thumb Screw

We've all been there—you're in the middle of a job, you go to swap out your gun or check your drive rolls, and that little thumb screw that holds everything together either strips out, breaks, or rolls under the workbench never to be seen again. The Lincoln Electric T13858 Screw and Thumb Assembly is the exact replacement you need to get your rig back up and running without jury-rigging a solution that might fail halfway through a bead.

This isn't just any bolt from the hardware store; it's the genuine Lincoln part designed specifically for your wire feeder. Whether you are running an LN-25 on a construction site or an LN-7 in the shop, this thumb screw is what locks your gun bushing or inlet guide in place. The "thumb" part of the assembly is key—it's designed to be tightened by hand, even when you're wearing welding gloves. This means you can make quick adjustments or swap out liners and guns without having to hunt for a screwdriver or a wrench.

Using the correct screw is more important than it looks. A screw with the wrong thread pitch can ruin the tapped holes in your expensive wire feeder casting, turning a five-dollar repair into a five-hundred-dollar headache. The T13858 is made of tough steel that resists stripping and holds tight against the vibration of the wire drive motor. It gives you the peace of mind that your connection is solid, so you can focus on the puddle, not on whether your equipment is going to rattle loose.

Don't let a missing piece of hardware slow down your production. Keep a spare Lincoln T13858 Screw and Thumb Assembly in your toolbox or parts bin. It’s a small part that plays a big role in keeping your wire feeding smoothly and your day going according to plan. Trust OEM parts to fit right the first time, every time.
