Our Shear Nuts, also known as Tamper Proof Nuts, Security Shear Nuts, or Break Away Nuts, are a high-security fastening solution designed for permanent installations. Available in Stainless Steel, BZP (Bright Zinc Plated), and Galvanised finishes, these nuts provide a secure and reliable fixing method for a wide variety of applications. The hexagonal head of a shear nut is designed to snap off during tightening, leaving behind a smooth, conical dome. This ensures a permanent, tamper-proof fastening that cannot be easily removed with standard tools. Why Choose Stainless Steel, BZP, or Galvanised Shear Nuts?
