Downloadable datasets availableAnnotation ability available
To be used on cutting edges and end bits in conjunction with No. 3 head plow bolts (Ref. ANSI B18.9) typically used on off-road self-propelled work machines as described in SAE J1116.
Cutting edges are further defined in SAE J737, J739 and J1304.
End bits are further defined in SAE J63.
When section thickness exceeds A in drawing 1 (Figure 2) (countersunk one side) or B in drawing 4 (countersunk both sides), use counterbore with diameter D, as shown in cross section drawings 2, 5 and 6, or extended countersink C, as shown in cross section drawings 3 and 7.
The inscribed circle of the square holes shall be concentric with countersink or counterbore within 0.03 in (0.8 mm).
The technical report covers technology, products, or processes which are mature and not likely to change in the foreseeable future.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
