Excellent corrosion resistance

I used these for an outdoor solar battery setup. After three months of exposure to humidity, there is zero sign of rust. The 304 stainless steel claim is definitely accurate.

Solid construction

Very sturdy screws. The round head looks clean on the finished battery box. The only minor issue is that the spring washers are a bit stiff, but they provide good tension once installed.

Best value for M4 battery hardware

I have bought similar sets from other vendors, but the quality control here is superior. Every screw was straight, and the threads were clean. Will definitely order again for my next batch of cells.

Perfect fit for my battery pack project

These screws are exactly what I needed for assembling my 32650 battery packs. The M4 threading is precise, and the included washers and nuts make assembly very quick. The stainless steel quality feels robust.

Complete kit saves time

Having the flat washer, spring washer, screw, and nut all in one matched set is a huge time saver. No need to hunt for compatible parts. Highly recommended for DIY electronics builders.

Good quality, slightly long shipping

The hardware itself is excellent. The cross head grips well without stripping, and the locking nuts hold tight. Only giving 4 stars because shipping took a bit longer than expected, but the product is great.

5 FAQ

Q: What is the length of the screw shaft?

A: The standard screw length in this set is 10mm. If you require a different length for a custom application, please contact us directly to check availability.

Q: Is the locking nut reusable multiple times?

A: Yes, the locking nuts are designed to be reusable. However, for critical safety applications involving high-vibration environments, we recommend inspecting the nylon insert for wear after several uses.

Q: Are these screws compatible with 26650 batteries as well?

A: While these are specifically designed for 32650 cell spacing, they can be used with 26650 batteries if your holder or bracket has M4 mounting holes. Please verify your specific casing dimensions before purchasing.

Q: Does this package include a wrench for the nuts?

A: No, this package includes only the hardware components (screws, nuts, and washers). Tools such as wrenches or screwdrivers are not included.

Q: Do I need a special screwdriver for the cross head?

A: No special tool is required. A standard Phillips #2 screwdriver works perfectly with these cross pan head screws.
