Great value for money

You get a lot of washers for the price. The zinc plating seems even, and I haven't seen any rust after a few months of use in my garage.

Heavy duty indeed

I use these in my workshop for heavy machinery maintenance. The spring tension is strong, and they don't flatten out easily under high torque. Highly recommended.

Solid construction

These are thicker than standard washers found at local hardware stores. They hold bolts tight very well. Just make sure you select the right size for your bolt diameter.

Essential for vibration prone areas

Used these on my motorcycle exhaust mounts. The lock feature works great against vibration. Very satisfied with the purchase.

Good quality, fast shipping

Bought the M8 and M10 sizes for a shelving unit. They are sturdy and fit perfectly. One star off because the packaging was a bit battered, but the product inside was fine.

Perfect for my automotive project

These washers are exactly what I needed. The galvanized coating looks solid, and the thickness provides great tension. No slipping on my suspension bolts.

5 FAQ

Q: Do these come with a certificate of material compliance?

A: For bulk industrial orders over 50kg, we can provide a material test report upon request. For standard retail packages, they comply with general ISO standards but do not include individual certificates.

Q: Are these washers suitable for outdoor use in rainy conditions?

A: While they are galvanized for corrosion resistance, they are best suited for indoor or protected outdoor environments. For constant exposure to harsh weather, stainless steel options might be more durable long-term.

Q: What is the exact thickness of the M10 washer?

A: The M10 thickened split lock washer typically has a thickness of approximately 2.5mm to 3.0mm, which is greater than standard DIN 127 specifications. Please refer to the detailed dimension chart in the product images.

Q: Can I mix sizes in one order?

A: Yes, we offer assorted kits that include a variety of sizes from M5 to M20. You can also purchase bulk packs of specific sizes individually and combine them in your cart.

Q: Will these work with metric bolts only?

A: Yes, these washers are designed specifically for metric bolt sizes (M5 through M20). They are not compatible with imperial (UNC/UNF) bolt sizes due to differences in inner diameter measurements.
