Stainless S-9 Undercut Anchor Data

Presented below are four different stainless steel options for the S-9 Undercut Concrete Anchors. 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.

These loads are valid where embedment is sufficient to assure steel failure; that is concrete shear cone strength is greater than steel strength.NOTE: 1-1/4” & 1-1/2” diameter SS S-9 – ASTM A193 – 316 B8M Class 2 Max Factored Design Loads are limited to the yield strength per SectionR17.4.1.2 of ACI 318.
