I have a new Honda HS928TCD blower.  Apparently a change was made in the past for the shear pins for the HS928 so now there are two types available, depending on the frame serial number. The older style pins have a P/N of  95701-06016-00 and the newer style is 92101-06016-0A. Since I have a bunch of the older style shear pins, I am wondering what the nature of the change was and if the older type of shear pins will work for the newer model.  If the old style is used on the new frame type, is there a danger to the gearcase because the shearing point is different?  See  http://www.boats.net/parts/search/Honda/Snow%20Blower/0/HS928%20WAS%20SNOW%20BLOWER%2C%20JPN%2C%20VIN%23%20SZAS-1100001%20TO%20SZAS-1129999/AUGER/parts.html for the illustrations.  Any ideas out there?

The after market shear pins designed for the Honda only cost 66 cents for the pin and the nut.  Why take a chance?

The Canadian Ebay seller responded to my question regarding the "grade" or hardness of these replacement pins;

 " Hello these will fit the Hs 624. The grade is the exact replacement grade as specified by honda for this application. They would be commonly known as grade 8.8 metric."

Can anyone tell what a "metric grade" might be?

 

Underdog,

Yes.  My bolts are in metric and say they are 8.8.  The 8.8 is written on the head bolt.

I did order some of these - still in the mail - should be here in a few days.  I'll let post here what they look like when I get them.

The spare spare shear pins that came with my new Honda 928 are hex head flange bolts.  On the cap, there is an "8" in a circle with an underline.  The nuts are self locking type.  I'll see how they compare to the new ones.

 

Left bolt is from my Honda dealer ($0.36) and Right bolt came with the blower.

The one on the right is the type that came with my blower too.  But I haven't taught them to play the piano yet.

Only Yamaha thing we have at our home is the piano.

Not an option fpor the Honda.  But does it blow snow too?  Would be nice to listen to a little Mozart while following the Yamaha  LOL.  Comment from Mr. Rubinew??

Is there such thing as a "metric" grading system for bolts that is different from a non-metric "grading system" for bolts.

Or is a grade "8" all there is.  I am not familiar with the grading system for bolts.  "8" sounds pretty hard (or strong) to me.

I would think that we would be looking for a softer bolt to protect our auger gear box.
