Home improvement fastener designed to protect assemblies by shearing at a predictable point to prevent wider damage. Peace of mind for installers and maintenance teams who need tamper-resistant, single-use fixings. Is the Generic M10 Shear Nut the right choice for your security-critical M10 connections?

⚡ At a Glance
  • Shear Performance: Predictable fail-safe shearing under overload protects connected equipment
  • Best for: Security installations and mechanical assemblies needing sacrificial failure to prevent damage
  • Not ideal for: Applications requiring reusable or adjustable fastenings after installation

Made from A4 marine grade stainless steel with a snapoff security design. Engineered to act as a sacrificial M10 nut that shears at a predictable point to protect assemblies.


Corrosion resistance - thanks to A4 marine grade stainless steel

A4 marine grade stainless steel is specified for environments prone to moisture and salt exposure, offering enhanced resistance to pitting and corrosion compared with standard grades.

Longer service life in outdoor and coastal settings keeps fixings reliable and reduces replacement frequency.

Predictable sacrificial protection - with snapoff shear design

Snapoff shear geometry creates a defined weak point that severs when torque exceeds the design limit, preventing overload from transmitting to the rest of the assembly.

Protects more expensive components by sacrificing the nut, making repairs simpler and damage more localised.

Tamper resistance - thanks to tamper-proof Permacone form

Permacone-style tamper geometry limits removal with standard tools once installed, deterring unauthorised disassembly and tampering.

Adds an extra security layer for fixed installations where unauthorised access must be minimised.

❓ Frequently Asked Questions

Q: Are these nuts suitable for outdoor or coastal use?

A: Yes. A4 marine grade stainless steel is intended for corrosive environments and is suitable for outdoor and coastal applications.

Q: Do the nuts shear reliably under overload?

A: User feedback reports reliable and predictable shear-off behaviour under load, designed to protect connected equipment by sacrificing the nut when necessary.

Q: What size are the nuts and how many come in a pack?

A: Thread size is M10 and the pack contains six nuts.

🏆 Our Verdict

The M10 shear nuts are well suited for installers, maintenance teams and security-conscious purchasers who need sacrificial fastenings to protect assemblies. Marine-grade stainless construction combined with a snapoff shear and tamper-resistant Permacone form delivers corrosion resistance, predictable sacrificial behaviour and deterrence against unauthorised removal. While cost-conscious buyers should factor in replacement frequency for sacrificial fixings, long-term corrosion resistance and damage prevention provide practical value over time.
