These external shakeproof washers are designed to help keep bolted joints secure in demanding, vibration-prone environments. Made from quality materials and available with a range of protective finishes, they deliver strong durability and dependable corrosion resistance for long service life.

The external tooth design bites into the mating surfaces to resist loosening, while the washer profile helps distribute load evenly to reduce stress on bolts, nuts, and assembled components. This improves joint stability and supports consistent clamping force across repeated use.

Manufactured to recognised industry standards including DIN 125A, BS4320, and DIN 6798, these washers are a trusted choice for professional fastening applications across construction, automotive, maintenance, and heavy engineering. Ideal for use wherever vibration resistance, secure fastening, and reliable load distribution are essential.
