O-CONN 20 Inch Chainsaw Chains 4-Pack .325 Pitch .050 Gauge 80 Drive Links — Hard Chrome, Semi-Chisel

O-CONN replacement 20" chainsaw chains — a 4-pack of .325" pitch, .050" gauge, 80 drive-link chains built to fit Husqvarna, Craftsman, Makita and similar 20" bars for durable, consistent cutting.

When your saw needs reliable replacement chains, this O-CONN four-piece set delivers size-matched parts made for everyday timber and property work. Each chain is engineered to the common .325" pitch and .050" gauge standard with 80 drive links, so installation is straightforward for compatible saw models. The group pack keeps spares on hand so you can swap a dull chain quickly and reduce downtime on job sites or at home.

Will these chains fit my Husqvarna 450 Rancher or similar models?

Yes — the chains are designed to fit many popular 20" bar models that accept a .325" pitch and .050" gauge chain with 80 drive links. Confirming bar length and drive link count on your existing chain or manual ensures compatibility before ordering.

• Fits Husqvarna: 450 Rancher, 445(E), 450(E), 545(MII), 550XP(MII)
• Also fits Craftsman 358.38200, 360.35200, 360.35201 and Makita EA5600F
• Matches 20" bar length, .325" pitch, .050" gauge, 80 drive links

How are these chains constructed and what makes them durable?

O-CONN chains use a semi-chisel cutter profile and high-toughness steel to balance cutting performance with wear resistance. A hard chrome plating on the outside of cutting links and heat-treated rivets increase surface hardness and slow wear from repeated use.

• Semi-chisel cutters for efficient cutting and simpler maintenance
• Industrial hard chrome outer layer to resist abrasion
• Hardened, quenched rivets for stronger link joints and longer life

What cutting characteristics can I expect during use?

These chains are tuned for steady, predictable cuts that minimize vibration and operator fatigue. The profile and build reduce stretch and the frequency of readjustments, making them suitable for routine pruning, firewood, and general saw work.

• Consistent cutting speed across wood types
• Reduced chain stretch and fewer tension adjustments
• Lower kickback tendency compared with aggressive profiles

How should I maintain and swap these chains for best results?

Proper sharpening, correct tensioning, and routine lubrication extend chain life and keep cutting performance steady. Keep a spare from the 4-pack ready so you can swap quickly rather than work with a blunt chain that increases wear and stress on the saw.

• Sharpen cutters with a .325"-compatible file or professional service
• Set chain tension per saw manual—snug but with slight play
• Use bar and chain oil to reduce friction and prevent overheating

Who this is for: This O-CONN 4-pack is aimed at homeowners, landscapers and occasional loggers who use 20" chainsaw bars and want value in quantity plus durable replacement parts. It’s a practical purchase for anyone maintaining a Husqvarna 450-series, compatible Craftsman or Makita unit who prefers having ready spares for uninterrupted cutting tasks.
