Want to have a supply of shear pins for my Woods rotary cutter. The manual recommends a Grade 2 NC 1/2"X3" shear bolt with a lock nut.
Went to my local Quality Farm and Home Supply store which was out of Grade 2 shear bolts. Asked one of the "associates" if they had anymore and, of course, they didn't since all of the Grade 2 hardware was on sale. He said that I could use a Grade 5 since it was harder and would shear cleaner than the Grade 2. Passed on the advise since I don't trust these guys very much. A personal observation with the store i.e. a collection of village idiots based upon previous experiences in other areas.
I had the opportunity to stop at my JD dealer to ask a general question about my 4100 (Boy, the 4200 and 4300 are looking good - Hey, honey can I ..... /w3tcompact/icons/wink.gif). While I was there I asked for some of the Grade 2 shear bolts and they recommended the same thing as the Quality Farm and Home store (must apologize to QHF people /w3tcompact/icons/blush.gif). They gave me Grade 5 bolts with nylon locking heads. Is this correct?
When it comes to bolt grading, my head flips to the side and I begin to drool trying to understand what the differences are.
Grade 2 is softer than Grade 5. Grade 5 seems to be better due to the hardness of the metal (shears better) whereas Grade 2 is softer and may bend rather than shear. (This is why my head flips and drooling commenses.....)
Thoughs, comments, recommendations?
