Good but Stiff
Works well but requires a firm hammer tap to seat properly. Otherwise solid product for general use.

Excellent Locking Power
These washers fit perfectly on my round nuts. The six-prong design really keeps everything tight during operation.
Q: Is this material resistant to saltwater?
A: 304 Stainless Steel offers good corrosion resistance, but 316 is recommended for prolonged saltwater exposure.
Q: Do you offer bulk pricing?
A: Yes, please contact us directly for orders exceeding 500 units for a discount.
Q: Can these be reused after removal?
A: They can be reused if the prongs are not permanently deformed during removal.
Q: Is this compatible with M30 round nuts?
A: Yes, please select the M30 size option from the variant menu to ensure proper fit.
Q: What tool is needed for installation?
A: A standard hammer or a press tool is sufficient to seat the washer into the nut slot.
