Shear pin?

[DFB]

Hey guys,

Check this one out. The attachment shows the grade and manufacture mark of this bolt that came on my Worksaver Backblade from CT. It sheared while out plowing snow. This one is clearly marked 307A, the ASTM grading for a low carbon steel bolt and according to the register the O F mark identifies the manufacturer as

Oriental Fastener Industry Co.,Ltd
299 Yu-Lin Road
Chiao-Tou Village
Kaohsiung Hsien Taiwan R.O.C. /w3tcompact/icons/smile.gif

I always thought that the marks were unique to the trade!
