Overview

This pre-wound replacement spool drops directly into compatible string trimmers, eliminating the hassle of hand-winding line. Worn or empty spools leave trimmer owners without a cutting edge mid-job. Keeping spare aftermarket spools on hand ensures minimal downtime and consistent line feed during yard work.

Key specifications

  • Pre-wound replacement trimmer spool
  • Direct-fit for listed trimmer models
  • Bump-feed compatible winding pattern

Compatibility

This spool is designed for Hyper Tough string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.

Installation notes

Power off the trimmer and press the tabs on the spool housing to release the cover. Pull out the empty spool and clear any debris from the housing interior. Drop in the new spool, route the line through the eyelets, and snap the cover back on.

Common questions

Q: Will this replacement part fit my Hyper Tough 20V Max Cordless String Trimmer model HT19-401-003-16, or is it only for HT21-401-003-02 and HT22-401-03-05?

Yes, this replacement part is listed as compatible with Hyper Tough 20V Max Cordless String Trimmer models HT19-401-003-16, HT19-401-003-07, and HT-19-401-003-06, along with HT21-401-003-02, HT21-401-003-03, and HT22-401-03-05. The safest approach is to match your full model number exactly from the trimmer label before installing.

Q: I have model HT-19-401-003-06. Is this the correct replacement if my original trimmer part is worn or damaged?

If your trimmer label shows HT-19-401-003-06, this is one of the compatible models for this replacement part. It’s designed as a direct replacement for the listed Hyper Tough 20V Max cordless string trimmer versions, so it should fit properly as long as the model number matches.

Q: Do I need to remove the battery before installing this replacement part on my Hyper Tough 20V Max trimmer, and is there any maintenance I should do after installation?

Yes, always remove the 20V battery before doing any installation or maintenance on the trimmer for safety. After installing the part, check that it is seated securely, inspect the string head area for debris, and test the trimmer briefly to make sure everything runs smoothly without wobble or rubbing.

Before you buy — how to verify fitment

  1. Find your trimmer model number. It's usually on a label on the motor housing, battery slot, or lower shaft.
  2. Check spool compatibility. Compare the model number with the compatibility list above.
  3. Verify line gauge. Confirm the line thickness matches what your trimmer head requires by checking your manual or the old spool.
  4. Inspect the spool housing. Make sure the spool diameter, cap, spring post, and feed style match your trimmer head.

Frequently asked questions

How do I know this spool fits my trimmer?

Check your trimmer model number against the compatibility list above. Then verify the line gauge (.065, .080, .095) matches what your trimmer head requires — it's usually printed on the spool cap or in the manual.

Can I rewind a pre-wound spool?

Yes. Once the factory line runs out, you can rewind the spool with bulk trimmer line of the same gauge. Pre-wound spools just save time on the first load.

How often should I replace the spool?

Replace the spool when the line no longer feeds properly, the spring loses tension, or the spool body is cracked. Under normal weekend use, a spool lasts 2–4 refills before the housing wears out.

What gauge trimmer line should I use?

Match the gauge to your trimmer's power: .065" for light-duty electric trimmers, .080" for mid-range cordless, and .095" for gas-powered or heavy-duty models. Using too thick a line can stall the motor.
