Stainless S-9 Undercut Concrete Anchors

Presented below are four different stainless steel options for the S-9 Undercut Concrete Anchor.  Generally, the Stainless 304 B8 Class 1 and the Stainless 316 B8M Class I S-9 Undercut Concrete Anchors are the least expensive and most readily available of the Stainless Steels.  The Stainless 304 B8 Class II S-9  boasts the highest strength among the Stainless Steels, while the 316 B8M Class II S-9 provides the combination of high strength and the highest level of corrosion resistance.
