Shear bolts - зрізні болти

Shear bolts are a type of fastener designed to fail (shear off) at a specific load to protect a machine or structure from damage.

What they do

A shear bolt is intentionally the “weak link” in a mechanical system. When force becomes too high, the bolt breaks before more expensive or critical parts are damaged.

Where they’re used

You’ll commonly find shear bolts in:

Snow blowers / augers (very common example) Agricultural machinery (tractors, combines, PTO shafts) Industrial equipment with rotating or overload-prone parts Safety mechanisms in some mechanical assemblies

How they work

The bolt is chosen for a specific shear strength. Under normal operation, it holds parts together like a regular bolt. If the machine jams or overloads, the bolt shears (snaps cleanly). After failure, it is replaced rather than repairing major components.

Why they’re useful

Cheap and easy protection against expensive damage Simple “mechanical fuse” concept No sensors or electronics needed Important note

Shear bolts are not interchangeable with regular high-strength bolts. Using the wrong grade or replacing them with stronger bolts defeats their safety purpose and can lead to serious damage.
