Fifchall 18-inch Chainsaw Chain Pack for Stihl .325 Pitch .050 Gauge 68 Drive Links — 4-Pack, Heat-Treated Chrome

Four replacement 18-inch chains designed to fit Stihl models with .325" pitch, .050" gauge and 68 drive links, sold as a pack for quick swap-outs.

These Fifchall chains are aftermarket replacements engineered to match Stihl guide bars that require a .325" pitch and .050" gauge with 68 drive links (commonly used on newer MS250 and MS251 series). Built from heat-treated, corrosion-resistant steel and finished with chrome plating on the cutters, the set comes with hardened rivets and oil-storage grooves to help maintain cutting performance. Before buying, confirm your bar length, pitch, gauge and drive link count stamped on the guide bar or listed in your owner’s manual to ensure compatibility.

Will these chains fit my Stihl MS250 or MS251?

They fit Stihl saws that use an 18-inch bar with .325" pitch, .050" gauge and 68 drive links—this is common on post-2022 MS250 and MS251 variants. Older models sometimes use a thicker .063" gauge chain; those will not work with this set.

• Compatible: 18" bar, .325" pitch, .050" gauge, 68 drive links.
• Check: side-stamped bar markings or owner’s manual for exact specs.
• Not compatible: bars requiring .063" gauge chains (older MS250 variants).

How do these chains perform compared with OEM options?

Fifchall chains are manufactured from premium German-style steel and heat-treated components, offering sharp cutters and hardened rivets designed for reliable, consistent cutting. They aim to deliver smooth cuts and resist corrosion thanks to chrome plating and built-in oil grooves, though real-world results depend on maintenance and saw setup.

• Material: heat-treated steel for wear resistance and durability.
• Finish: chrome-plated cutters to reduce corrosion and wear.
• Design: oil grooves and hardened rivets for smoother operation.

What should I know before installation?

Installing a chain correctly is crucial: it must be oriented so the cutter faces forward on the top of the bar and tensioned per the saw manufacturer’s guidance. Incorrect direction or incorrect tension will prevent cutting and can damage the bar or chain.

• Direction: cutters face forward along the bar’s top edge when installed.
• Tension: set to manufacturer's spec—tight enough to seat, loose enough to move freely.
• Maintenance: sharpen cutters or replace if damaged; check rivet integrity regularly.

What safety and maintenance practices should I follow?

Use proper protective equipment, keep the chain sharp, maintain correct chain tension and use the right bar oil. Regular inspection for chips, bending, or loose rivets extends chain life and reduces the chance of kickback or premature wear.

• Wear PPE: gloves, eye protection, and hearing protection during use and maintenance.
• Lubrication: use recommended chain oil and verify bar oiling while operating.
• Inspection: check cutters, rivets and tension before each use; replace chains showing excessive wear.

Who is this for: This 4-pack from Fifchall is aimed at homeowners, landscapers and professional users who own compatible Stihl saws and want spare or replacement chains for frequent jobs or to keep a rotation of sharpened chains ready. It’s a cost-effective option for anyone needing multiple reliable chains for continuous cutting tasks, provided the chain pitch, gauge and drive link count match the saw’s specifications.
