Some common types of galvanized ring shank siding nails include:

Casing nails

Typically used for attaching moldings and trim, casing nails have a small diameter head that sits flush with the surface. Lengths commonly range from 1 to 2 inches.

Face nails

These nails have a larger head that is intended to be exposed on the face of siding or trim materials. Face nails are usually between 1.5 to 3 inches long.

Siding nails

Specifically designed for fastening siding materials, siding nails have ringed shanks that grip into wood and resist withdrawal. Ring shanks start about 0.5 inches below the head. Lengths typically range from 1.25 to 3 inches.

Blind nails

Similar to siding nails but without an exposed head, blind nails are driven in at an angle so the head is concealed by siding panels. They have full length ring shanks. Common lengths are 1.5 to 3 inches.

Roofing nails

Used for attaching asphalt shingles and roofing felt, roofing nails have larger heads and are upward-tapered for easy driving into shingles. Lengths range from 0.75 to 2.5 inches.

The key differences between these types of galvanized ring shank nails are the head size and shape, length, and purpose. The ring shank provides resistance to withdrawal, making them a good choice for fastening siding and roofing materials that may be exposed to weather. Galvanizing protects against corrosion.

While these are common types, there are many variations and specialized nails available depending on the manufacturer and intended application.
