Overview
This 2-pack of aftermarket 16-inch replacement chains is designed to fit select Worx chainsaw models. It serves as a drop-in replacement when the original chain becomes dull past the point of resharpening, develops a damaged cutter, or has stretched beyond the tensioner’s adjustment range. Having a spare on the shelf eliminates trips to the dealer mid-project.
Key specifications
- Bar length: 16”
- Pitch: 3/8 LP
- Drive links: 57DL
- Quantity: 2-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, and does the 57 drive link 3/8LP .050 spec need to match exactly?
Yes, this chain is made for the Worx WG300, WG303, WG303.1, and WG304 that use a 16-inch bar with 57 drive links, 3/8” low-profile pitch, and .050” gauge. Those specs need to match your saw and bar exactly, or the chain may not seat correctly on the bar and sprocket.
Q: Can I use this 2-pack chain on a different 16” chainsaw if the bar is also 16 inches long?
Not by bar length alone. A 16-inch bar can use different chain configurations, so you also need to confirm 57 drive links, 3/8 LP pitch, and .050 gauge before installing it on any non-listed saw.
Q: What’s the best way to install and maintain these chains on my Worx WG303.1 so they last longer?
When installing, make sure the cutter teeth on the top of the bar face forward and then tension the chain so it sits snugly but still pulls around by hand with gloves on. Keep the chain oiled, check tension after the first few cuts, and sharpen it as soon as you notice it cutting slowly or producing fine dust instead of chips.
