Title:Metric Countersunk Holes for Cutting Edges and End Bits (STABILIZED Oct 2011)
Issuing Committee:Mtc1, Loaders, Crawlers, Scrapers And Mounted Attachments
Scope:This document is to be used on cutting edges and end bits in conjunction with metric bolts (reference ISO 7852-1982) typically used on off-road, self-propelled work machines as described in SAE J1116. The cutting edges are further defined in SAE J737, J739, J1304, and J1581. The end bits are futher defined in SAE J63.
