DWO1DT995 Weed Trimmer Head Cap Replacement for Dewalt with Weedeater Head Cap and Spring, Weed Wacker Head 20V Part for Dewalt ‎Weed Trimmer Head DCST922P1 DCST922B DCST972X1, 2 Pack

What It Is

This is a replacement cap and spring set for the head of DEWALT 20V MAX weed trimmers. It secures the spool and line inside the trimmer head, allowing the head to function properly during use.

Fitment & Compatibility

Check that your trimmer is one of these DEWALT 20V models: DCST922P1, DCST922B, or DCST972X1. This cap is not universal—it will not fit older 18V or gas-powered DEWALT trimmers, nor will it work with other brands. Before buying, remove your old cap and spring and visually compare them to the images. Measure the cap diameter (roughly 1.5 inches) and spring length (about 1 inch) to confirm. This is an aftermarket part, not OEM, so the fit may be slightly tighter or looser than the original.

Key Things to Know

• Quality: Users report the cap is durable plastic, but the spring can feel weaker than OEM. If your trimmer head doesn’t lock or line feeds unevenly, the spring may be the issue.
• Installation: Easy—no tools required. Push the spring into the head, place the cap over it, and twist to lock. Watch a quick video if you’re unsure about alignment.
• Common gotcha: The cap may pop off under heavy use if the spring isn’t seated fully. Double-check that it clicks into place securely.
• Pack size: Comes as a 2-pack, so you have a spare for future replacements.

Should You Buy It

If you own one of the listed DEWALT 20V trimmers and your cap is cracked, lost, or the spring has worn out, this is a cheap, functional fix. It won’t match OEM quality or fit perfectly, but for $10.39 it’s a practical stopgap. Skip it if you want guaranteed OEM reliability or if your trimmer model isn’t listed.
