S20SNDB 4" Type 304 Stainless Steel Ring-Shank Wood Siding Nails- 25# Box

S20SNDB stainless steel ring shank wood siding nails by Simpson Strong-Tie are 4" long made of type 304 stainless steel. Each box contains approximately 1,850 nails.

The nails have a 1/4" head with a checker pattern to reduce glare from sunlight. The shank is .131" (10 gauge) and has annular ring shanks to increase pullout resistance. This provides a secure attachment that reduces the cupping of siding boards. The nails have a diamond point for easier driving.
