Overview
This 3-pack of aftermarket 16-inch replacement chains is designed to fit select Worx chainsaw models. It replaces the factory chain when the original becomes dull beyond resharpening, damaged, or stretched past the tensioner’s range. Keeping a spare chain on hand means less downtime during cutting season — swap in a fresh chain and keep working while you sharpen the old one on the bench.
Key specifications
- Bar length: 16”
- Pitch: 3/8 LP
- Drive links: 57DL
- Quantity: 3-pack
- Type: Semi-chisel (aftermarket replacement)
Compatibility
Engineered to match the specifications of select Worx chainsaw models, this chain drops in without modification. Before ordering, verify the three critical numbers — pitch, gauge, and drive-link count — against the stamp on your guide bar. A mismatch in any one dimension means the chain won’t fit safely.
Installation notes
Start by removing the battery or disconnecting the power cord. Take off the bar-cover plate and release bar tension. Pull the old chain out of the groove and off the sprocket. Seat the replacement chain into the bar groove — cutters must face forward on the top of the bar. Engage the chain on the drive sprocket, reinstall the cover, and adjust tension so the chain lifts about a dime’s width off the bar and springs back. Hand-rotate the chain to check for binding before powering on.
Common questions
Q: Will this 16” replacement chain fit my Worx WG304 chainsaw, and does the 57DL / 3/8LP / .050 spec need to match exactly?
Yes, this chain is made for Worx WG300, WG303, WG303.1, and WG304 saws that use a 16-inch bar with 57 drive links, 3/8” low-profile pitch, and .050” gauge. Those specs do need to match your bar and saw setup exactly, or the chain may not seat correctly on the bar or drive sprocket.
Q: I have a Worx WG303.1 with the original 16-inch bar—can I install one of these chains without changing the bar or sprocket?
If your saw is still using the original 16-inch setup that calls for 57 drive links, 3/8 LP pitch, and .050 gauge, this chain should install without changing the bar or sprocket. Just confirm the markings on your current chain or bar first, then set the chain tension properly after installation and recheck it after the first few cuts.
Q: What maintenance should I do with these 16” chains to keep them cutting well and avoid premature wear?
Keep the chain properly tensioned, maintain bar-and-chain oil flow, and touch up the cutters regularly with the correct file for a 3/8 low-profile chain. It’s also a good idea to inspect the bar groove and drive links for debris or burrs each time you swap chains, especially since this 3-pack makes it easy to rotate chains during heavier use.
