Walmart Chainsaw Chains: Sizes, Fit & Cross-Reference Guide

Walmart sells chainsaw chains in gauges from .043″ to .063″ and pitches from 1/4″ to .404″ — but a chain only fits if pitch, gauge, and drive-link count all match your bar exactly. Buying the wrong combination wastes the trip and can jam mid-cut. This guide covers how to measure your old chain, which Walmart-carried brands (Oregon, SALEM MASTER, Husqvarna) fit common saws, and why Walmart won’t sharpen a chain in-store.

What Chainsaw Chain Sizes Does Walmart Carry?

Walmart stocks replacement chains for the bar lengths most homeowners and professionals actually run, from small pruning saws up to full-size felling saws. Chains are sold by bar length, but bar length alone won’t get you a fit — you also need the pitch, gauge, and drive-link count printed on your old chain or bar.

Bar Length	Typical Use	Common Pitch/Gauge Combos
8″ – 12″	Pole saws, small pruning saws	1/4″ pitch, .043″–.050″ gauge
14″ – 18″	Homeowner firewood and yard cleanup	3/8″ LP or 3/8″ pitch, .050″–.058″ gauge
20″ – 36″	Heavy-duty felling, milling	.325″ or 3/8″ pitch, .058″–.063″ gauge

These are the combinations Walmart’s listings group chains by (for example, a 20-inch SALEM MASTER chain listed at .058″ gauge, .325″ pitch, 76 drive links). Two chains can both say “20 inch” and still not interchange if the gauge or drive-link count is different.

How to Measure Your Chain Before You Buy a Replacement

Measuring your own chain takes about five minutes and prevents a second trip. You need three numbers: pitch, gauge, and drive-link count. Here’s the method that actually works without special tools.

1. Find the pitch: Measure the distance between the centers of any three consecutive rivets, then divide by two. Most saws run 1/4″, 3/8″ low-profile, 3/8″, or .325″ pitch — the number is often stamped on the drive link itself.
2. Check the gauge: The gauge is the thickness of the drive link where it sits inside the bar groove. A caliper reads this most accurately; without one, compare your old chain directly against a new one’s packaging at the store — the four common gauges (.043″, .050″, .058″, .063″) are close enough that eyeballing it gets people the wrong chain.
3. Count the drive links: Mark one drive link with tape, then count every link along the entire chain (the inner tooth that sits in the bar groove, not the cutter on top) until you reach the mark again.
4. Cross-check against your bar or manual: The pitch is usually stamped on the bar near the mount, or listed in the chainsaw’s owner’s manual — use it to confirm your measurement before buying.

Chain is a looped cutting attachment made of individual drive links, tie straps, and cutters that a chainsaw’s sprocket drives around the guide bar. It only functions correctly when its pitch matches the drive sprocket and its gauge matches the bar groove width — mismatching either one causes binding, poor tension, or the chain jumping the bar entirely.

“A chain that’s even .003 inch off in gauge will still slide onto the bar, but it binds under load within a few cuts — I’ve had people bring me a chain that looked identical to their old one but was actually ground for a completely different saw family.”

Chainsaw Chains Walmart Actually Sells

Walmart’s own listings (both in-store and online) center on a handful of real, verifiable models rather than one universal chain. The three below cover the sizes most homeowners search for:

Model	Specs	Best For
Oregon S62	18″, 3/8″ pitch, .050″ gauge	Mid-size homeowner gas saws
SALEM MASTER 20″	.325″ pitch, .058″ gauge, 76 drive links	Larger yard-cleanup and felling saws
Generic 20″ replacement	.325″ pitch, .058″ gauge	Cross-brand fit on many 20″ bars

All three are genuine, currently-listed Walmart products — not off-brand chains repackaged under a generic name. Cross-check the pitch and gauge against your own measurements from the section above before ordering either in-store pickup or delivery.

Price generally tracks bar length and drive-link count rather than brand: short 8–12 inch pruning chains typically run under $15, mid-size 14–18 inch homeowner chains (like the Oregon 18″ above) land in the high-teens to mid-$20s, and 20-inch-plus heavy-duty chains with higher drive-link counts run $25–$45. A chain priced far outside that range for its size is worth double-checking against the listed specs before buying.

Does Walmart Sharpen Chainsaw Chains In-Store?

No — Walmart does not offer an in-store chainsaw chain sharpening service. Its outdoor power equipment section sells the tools to do it yourself (hand-crank guides, files, and electric chain grinders) but does not run a sharpening counter the way some hardware stores do. If your chain is dull rather than worn out, a $15–$30 manual filing kit or electric sharpener is usually cheaper than a full replacement chain.

Chainsaw Chain Maintenance and Sharpening Tips

A correctly-fitted chain still needs regular care to cut straight and last through a season. These steps apply whether you bought new from Walmart or reused an existing chain on a new bar.

1. Clean after every use: Remove the chain, brush off sawdust and pitch with a wire brush, then wipe it down before storage.
2. Check tension before each start: A chain that sags off the bottom of the bar by more than about 1/8″ is loose enough to derail.
3. File at a consistent angle: Most chains sharpen at a 25–30 degree angle — check your chain’s packaging, since low-kickback chains sometimes use a shallower angle.
4. File every tooth the same number of strokes: Uneven filing makes the saw pull to one side mid-cut.
5. Check the depth gauge after several sharpenings: Once the cutters wear down, the depth gauge needs filing too or the chain stops biting into the wood.

Safety Gear to Pair With a New Chain

A sharp new chain cuts faster and more aggressively than a worn one, which raises the stakes on basic protective gear. At minimum:

• Chainsaw chaps: Cut-resistant fibers jam a moving chain almost instantly on contact.
• Face shield and ear protection: Combined helmet units cover both in one piece of gear.
• Cut-resistant gloves: Protect hands during chain changes and bar cleaning, not just cutting.
• Safety glasses under the face shield: A mesh shield stops chips but not fine dust.

Chain choice matters here too — a saw with proper drive link count and low-kickback design reduces the chance of the bar jumping back toward the operator.

Frequently Asked Questions

What types of chainsaw chains does Walmart sell?

Walmart carries standard chains, low-profile (3/8″ LP) chains for smaller saws, and semi-chisel/full-chisel chains for heavier cutting, from brands including Oregon, SALEM MASTER, and Stihl-compatible replacements. Always match pitch, gauge, and drive-link count to your saw rather than the brand name alone.

How do I know what size chain my chainsaw needs?

Measure your existing chain’s pitch (distance between three rivets divided by two), gauge (drive link thickness with a caliper), and drive-link count (count every inner link around the loop). These three numbers, not just bar length, determine fit.

Does Walmart sharpen chainsaw chains in-store?

No, Walmart does not run an in-store chainsaw sharpening service. It sells filing kits and electric sharpeners for at-home use instead, which is usually the cheaper option for a chain that’s dull but not worn out.

Can I buy a chainsaw chain online at Walmart for pickup or delivery?

Yes. Walmart.com lists chainsaw chains by bar length and spec, with both home delivery and in-store pickup options at checkout, the same as most other outdoor power equipment parts.

What is Walmart’s return policy on chainsaw chains?

Most general-merchandise items at Walmart, including chainsaw chains sold and shipped by Walmart, fall under the standard 90-day return window with a receipt. Marketplace-seller items can carry different windows, so check the specific listing before buying.

Conclusion

Getting the right Walmart chainsaw chain comes down to three numbers — pitch, gauge, and drive-link count — not the bar length alone. Measure your old chain first, cross-check it against the listing before you buy, and budget for a filing kit rather than in-store sharpening if the chain just needs an edge, not a replacement.
