Husqvarna Chainsaw Bar Nuts (4) — Replacement flanged guide bar nuts, 13mm fit for most Husqvarna chainsaws

Husqvarna Chainsaw Bar Nuts (4) are original-style replacement nuts designed to secure the guide bar on most Husqvarna chainsaws, sold in an easy-to-open clamshell pack.

When your chainsaw’s guide bar retention hardware wears, corroded or missing bar nuts can make the saw unsafe or difficult to adjust. These four Husqvarna-compatible bar nuts follow the manufacturer’s original dimensions and include a flange side for proper retention, so you get consistent fitment and straightforward installation with a standard 13mm scrench. Packaged in a clear clamshell, they’re convenient to store in a toolbox or replacement parts drawer.

How do these bar nuts help keep my chainsaw running safely?

The bar nuts hold the guide bar in place and maintain correct chain tension—critical to safe operation. Worn or loose nuts allow the bar to shift, increasing wear on the sprocket and chain and raising the risk of accidents. Replacing worn nuts restores secure mounting and consistent chain adjustment.

• Flanged design provides stable retention against the bar’s mounting surface.
• Fits standard 13mm scrench for easy tightening and loosening.
• Sold as a set of four so you have spares for multiple saws or future maintenance.

Will these nuts fit my Husqvarna model?

These bar nuts are designed to match Husqvarna’s common guide bar mounting specifications and will fit most Husqvarna chainsaws. Compatibility depends on the model year and specific bar configuration—compare nut dimensions to your existing hardware to confirm. If your saw uses a proprietary or nonstandard mounting, verify fit before installing.

• Intended for most Husqvarna saws using standard bar mounting studs.
• Compare to original nuts and confirm 13mm scrench compatibility.
• Includes four nuts so larger shops or multi-saw owners have replacements ready.

How do I install these replacement bar nuts?

Installation is straightforward: remove the old nuts, position the guide bar and chain, then hand-thread the new nuts before final tightening with a 13mm scrench. Tighten incrementally and check chain tension during a test run. Avoid overtightening; the flange side should seat against the bar to prevent loosening from vibration.

• Hand-start threads to avoid cross-threading before final tightening.
• Use a standard 13mm scrench for accurate torque and fit.
• Check tension after a short run and retighten if vibration loosens hardware.

What materials and build quality can I expect?

These nuts follow original-manufacturer-style specifications for shape and functional features like the flange face, ensuring reliable retention and compatibility. They’re made to withstand normal outdoor use and the vibration common to chainsaw operation, but like all fasteners, they should be inspected for wear and corrosion on a regular maintenance schedule.

• Original-style dimensions for consistent fit with Husqvarna guide bars.
• Flange provides a broad seating surface to resist loosening.
• Pack of four makes it easy to replace damaged parts promptly.

Who is this for: These Husqvarna Chainsaw Bar Nuts (4) are ideal for homeowners, arborists, landscapers and maintenance crews who use Husqvarna chainsaws and want OEM-style replacement hardware. They’re especially useful if you perform regular chain and bar maintenance, manage multiple saws, or prefer to keep spare parts on hand to minimize downtime.
