Q: Im looking for shear screws, and Im unsure between the NAS1580 and NAS 1581, could you tell me the difference between them? Or it could indicate a shear screw that is countersunk?

Both NAS1580 and NAS1581 are countersunk 100 degree, the NAS1581 has a reduced size head diameter. The NAS1580 will have a larger diameter head.
