FUNKYWOO 20-Inch Chainsaw Chains — 4-Pack, 3/8" Pitch .050" Gauge, Heat-Treated Semi-Chisel

This is a 4-pack of 20-inch replacement chainsaw chains by FUNKYWOO — 3/8" pitch, .050" gauge, 72 drive links designed to fit many 20" bars on Husqvarna, Stihl and comparable saws.

If you need reliable spare chains for routine cutting, this set gives four heat-treated semi-chisel chains built for smoother cuts, improved wear resistance and lower vibration compared with some economy links. Each chain is finished with an industrial hard-chrome outer layer and hardened rivets for longer service life. Confirm your saw uses a 3/8" pitch sprocket and a .050" gauge bar plate before ordering — this package is intended for 20" bars on compatible models such as Husqvarna 455 Rancher, 460 Rancher, MS 391, and Stihl MS 290/MS 310 among others.

How do these chains perform during regular cutting?

The semi-chisel cutters are heat-treated for high toughness, giving consistent bite and good debris tolerance. Low-vibration geometry reduces operator fatigue and helps maintain steadier control over longer cutting sessions.

• Semi-chisel design for smooth, consistent cuts
• Low-vibration profile for reduced fatigue
• Heat-treated steel resists chipping under usual loads
• Suitable for limbing, felling and general firewood cutting

Will these chains fit my chainsaw model and bar?

They are made for 20" bars with a 3/8" pitch and .050" gauge and include 72 drive links. Fit depends on your saw’s sprocket pitch and bar plate gauge rather than the overall chain length alone.

• Compatible with many Husqvarna and Stihl models listed in the product details
• Works only with 3/8" pitch sprockets and .050" gauge bars
• Designed for 20" guide bars (check bar model and part numbers)
• Measure sprocket pitch and count drive links if unsure

How durable and easy to maintain are these chains?

The outer surfaces feature a hard-chrome layer to slow wear, and rivets are hardened for stronger link connections. Routine sharpening and proper tensioning keep performance consistent; the construction reduces the frequency of adjustments compared with untreated chains.

• Industrial hard-chrome coating for improved wear resistance
• Hardened rivets for reliable link strength under load
• Easier to maintain with typical sharpening intervals
• Reduced chain stretch and fewer mid-session adjustments

Are there safety notes or usage considerations I should know?

Chainsaw chains can cause kickback — this set is designed with a low-kickback profile but still requires experienced handling. Only use if you understand kickback dynamics and follow all chainsaw safety practices and training.

• Low-kickback geometry reduces but does not eliminate risk
• Wear proper PPE: eye, hearing, gloves and leg protection
• Keep chain tensioned and well-lubricated during operation
• Follow manufacturer instructions for mounting and sharpening

Who is this for: This 4-pack is ideal for homeowners, landowners and small-acreage operators who want spare chains on hand for frequent cutting, tree work or firewood processing. It also suits DIY mechanics and professional users who run compatible 20" bars and need durable, heat-treated chains that balance cut quality, wear resistance and vibration reduction. Before purchasing, verify your sprocket pitch and bar gauge to ensure a proper fit.
