YDTech® manufacturer of shear pins,nails or drive lock pins(S7)! supplier of mold guide pins,bolts and bushings stainless steel in china.

shear pins are designed to break in half if the auger strikes a hard object to prevent damage to the transmission and engine. If the shear pin is broken, the auger won’t be able to turn. the retaining clip is not included, you must purchase it separately to complete the assembly.

snowblower shear pins are designed to break in half if the auger strikes a hard object to prevent damage to the transmission and engine. If the shear pin is broken, the auger won’t be able to turn.

when making a metal object for a mechanical application, an alloy and tempering is usually selected to make the construction resistant to damage. the metal returns to its original shape after being deformed by an external force. A shear pin however is often tempered to make the metal brittle, so that it breaks or shatters rather than bends when the required force is applied.

If the snowblower's auger hits a hard object, the shear bolt breaks in half to prevent damage to the transmission and engine. If the shear bolt is broken, the auger won’t turn.

the material of a shear pin is selected and treated so that it is relatively resistant to fatigue ,. If material fatigue were to weaken a shear pin, the pin could potentially be broken by a force smaller than the original threshold force causing the mechanism to operate unintentionally, or a safety shear pin to break during normal operation of the machinery it protects.

snowblower shear bolt, locking nut sold separately. this part has been updated by the manufacturer; it no longer requires a spacer. shear bolts are designed to break in half if the auger strikes a hard object to prevent damage to the transmission and engine by stopping the auger from turning..
