CRAFTSMAN String Trimmer Spool Head (CMZST260H), Red

What It Is

The CRAFTSMAN CMZST260H is a replacement spool head for Craftsman string trimmers, designed to hold and feed trimmer line for edging and weed trimming. It’s a quick-load bump-feed head that reduces downtime when replacing line.

Fitment & Compatibility

• Model match: Fits Craftsman trimmers with a 0.080-inch or 0.095-inch line diameter. Confirm your trimmer’s shaft type (straight vs. curved) and head attachment (thread size: typically 10mm x 1.25 left-hand thread for Craftsman models).
• Check your model number: Look on the trimmer’s serial tag (e.g., 316.791190). The CMZST260H is OEM for many Craftsman gas and electric trimmers, but not universal. Avoid if you have a different brand (e.g., Echo, Ryobi) unless you verify thread pitch.
• Measurement: Head diameter is roughly 4.5 inches. Ensure it clears your trimmer’s guard and doesn’t hit the ground at your desired cutting height.

Key Things to Know

• Installation: Simple – remove old head (usually a counterclockwise turn), screw on new one. No tools required for most models, but a pin or screwdriver may help lock the shaft.
• Line loading: Bump-feed design – tap the head on the ground to advance line. Pre-wound spools are available, but you can also reload manually. Use only 0.080 or 0.095 line; thicker line may jam.
• Durability: Plastic housing is sturdy for residential use, but not for heavy commercial or rocky terrain – impacts can crack the casing.
• Gotcha: Some users report the bump knob can loosen over time; check tightness after first few uses.

Should You Buy It

Buy this if you own a compatible Craftsman trimmer and want a reliable, easy-to-load replacement head for routine yard maintenance. It’s a solid value for homeowners who prefer bump-feed over fixed-line heads, but skip it if you need a heavy-duty metal head for frequent commercial use or if your trimmer uses a different thread size.
