Stainless Steel All-Thread Bar

Presented below are four different stainless steel options for All-Thread-Bar anchoring.  Generally, the Stainless 304 B8 Class 1 and the Stainless 316 B8M Class I bars are the least expensive and most readily available of the Stainless Steels.  The Stainless 304 B8 Class II bar  boasts the highest strength among the Stainless Steels, while the 316 B8M Class II provides the combination of high strength and the highest level of corrosion resistance.  Check with your local WFEC Technical Rep for information on availability and lead times.
