We have taken the possibility of any corrosion even one step further! We now offer our Anchor Bolt Bushing, which is a simple plastic sleeve, made from super strong polypropylene, designed to eliminate any possible galvanic reaction between 1/2" anchor bolts and treated wood. The plastic sleeve slides over the anchor bolt, eliminating the contact between the anchor bolt and the treated wood, while the flanged top protects the nut and flat washer from touching the wood, as well. Not only is the anchor bolt hot dip galvanized to exceed plating recommendations, now it is also further protected by our Anchor Bolt Bushing plastic shield. BIG SAVINGS on BIG ORDERS ! Anchor Bolt Bushing $0.35, 100/$22.00, 500/$90.00, 2000/$280.00, 4000/$440.00
