How to Get Out a Stripped Allen Head Bolt on a Factory Sway Block
One of the most common problems we see when guys pull the factory sway block off — a stripped Allen head that won't budge. Here's the fix.
Factory Allen head bolts on the John Deere sway blocks strip out constantly — they've been torqued down for a decade or more, they're full of dirt and rust, and by the time you're trying to back them out, half the time the socket just spins. Good news: you don't need to drill it out or replace the sway block housing. There are two clean ways to get it out.
Option A — The Easy-Out Method
If you have an easy-out set (also called a screw extractor), this is usually the fastest path.
- Pick an easy-out that matches the hole diameter of the bolt.
- Center-punch the head of the bolt to give the easy-out a bite point.
- Drill a pilot hole straight down into the bolt head, deep enough for the taper of the easy-out to seat.
- Turn the easy-out counter-clockwise with a tap handle or T-bar. The reverse threads bite as they turn and back the bolt right out.
Option B — The MIG Welder Trick (our preferred way)
If you have a MIG welder, this is honestly the cleanest fix and takes about 30 seconds. This is what we show in the video above.
- Take a spare nut and set it on top of the stripped bolt head.
- MIG-weld the nut to the bolt head — a good solid tack around the inside of the nut, filling into what's left of the stripped Allen recess.
- Let it cool for a few seconds. The heat also helps break the corrosion bond in the threads.
- Put a wrench on the nut you just welded on and back the whole thing out. The heat + the fresh bite gets it out clean.
- MIG welder (Option B) OR easy-out set + drill (Option A)
- Spare nut — whatever size you can weld to, doesn't need to match the bolt threads
- Standard wrench or socket for the nut
- Center punch (Option A only)
