Perfect fit for my e-bike battery

These M6 screws and square nuts fit my 250 series electric bike battery terminals perfectly. The zinc plating looks durable and should prevent rust.

Good quality, fast shipping

Solid construction and the square nuts grip well without stripping. Arrived quickly and exactly as described in the short description.

Sturdy and reliable

Good value for a set of terminal bolts. They feel heavy-duty and the threading is clean. One nut was slightly tight but loosened up fine.

Universal compatibility confirmed

Worked great on my 400 model scooter. The M5 square nut design makes tightening much easier than standard hex nuts in tight spaces.

Essential for secure connections

Upgraded my old battery connectors with these. The vibration resistance is noticeable on rough roads. Highly recommend for motorcycle owners.

Solved my loose terminal issue

My battery kept losing connection due to vibration. These square nuts lock in place securely. No more starting issues on my 12V system.

5 FAQ

Q: What tool do I need to install the square nuts?

A: You will typically need a standard open-end wrench or an adjustable wrench that fits the M5 square profile. A socket set may also work depending on clearance.

Q: Will these fit a 36V battery system?

A: These are designed specifically for 12V universal systems. While the physical size may fit, we recommend checking your manufacturer's voltage specifications before use.

Q: Does this kit include washers?

A: This specific set includes the M6 screws and M5 square nuts only. Washers are sold separately if needed for your installation.

Q: How many sets are included in one package?

A: Each package contains one complete set of terminal bolts and square nuts sufficient for one standard battery connection point.

Q: Are these compatible with the 150 series model?

A: Yes, the product description explicitly lists compatibility with the 150, 200, 250, 350, and 400 series models.
