Description
M8 Shear nut in A2 stainless steel
The M8 Shear nut in A2 stainless steel is a fastener for bolted joints that need to be difficult for unauthorised persons to dismantle. Shear nuts typically have a hexagonal section for tightening with a spanner and a rounded head separated by a narrowed section, distinguishing them from a standard Hexagon nut.

Shear nuts are used in publicly accessible areas to secure signs, barriers, enclosures and structural components exposed to interference by third parties. Made from A2 stainless steel, the nut is suitable for outdoor use where corrosion resistance is important.
How it works
Nuts of this type are tightened with a spanner, and the narrowed section of the head is designed to shear off once the appropriate torque is reached. After it shears off, a hexagonal section remains that is difficult to grip with a standard spanner, making unauthorised removal more difficult.

Applications
- Securing components in public spaces
- Fixing signs, signage and enclosures
- Outdoor structures exposed to moisture
- Joints requiring protection against vandalism

Benefits for the installer
- M8 thread compatible with standard bolts and threaded rods
- A2 stainless steel material for outdoor applications
- Shear-off design makes removal by unauthorised persons more difficult
- Hexagonal section for tightening with a standard spanner
- Small parcel, convenient to transport
The M8 A2 Shear nut complements the range of fasteners for securing bolted joints. Use it with M8 bolts or threaded rods when the joint needs to resist unauthorised removal.
