DWO1DT995 Replacement Trimmer Head Cap Compatible with Dewalt DCST920 DCST970 DCST990 DCST925 Cordless String Trimmer Weed Eater,with Replacement Spring & Base Parts (5 Pack)

What It Is

This 5-pack replacement trimmer head cap (with springs and base parts) secures the cutting line spool inside the trimmer head on select Dewalt cordless string trimmers. It’s a wear-and-repair item for when the original cap cracks, strips, or won’t stay latched.

Fitment & Compatibility

Check before buying:

• Models: Fits Dewalt DCST920, DCST970, DCST990, and DCST925 cordless string trimmers (all 20V/60V Max variants). Not compatible with other brands or gas models.
• OEM vs aftermarket: This is an aftermarket replacement, not genuine Dewalt. The cap, spring, and base are designed to match OEM part numbers N486016 and N484509.
• Measurement: The cap diameter is approximately 1.5 inches. If your original cap measures close to this and your model is listed, it should fit.
• Pack contents: 5 complete cap assemblies (cap + spring + base). No spool or line included.

Key Things to Know

• Installation is tool-free – snap off the old cap, remove the old spring/base, drop in the new assembly, and press to lock. Takes under a minute per trimmer.
• Use the included spring – the spring is part of the latching mechanism. Reusing an old worn spring will cause the new cap to pop off.
• Quality note: Some users report slightly looser fit than OEM, but the 5-pack means you can swap a dud. The plastic is similar to factory grade, not brittle.
• Common gotcha: If your trimmer head is cracked or the spool hub is damaged, this cap alone won’t fix it – you’ll need a full head replacement.

Should You Buy It

Buy this if you have a listed Dewalt cordless trimmer and the original cap keeps popping off or the latch is worn. The 5-pack is cost-effective for heavy users or anyone with multiple Dewalt trimmers – you’ll have spares ready. Skip it if your trimmer head body is cracked or you need a complete head assembly.
