This bolt set is necessary in high corrosive areas that are near salt water oceans or in high humidity areas. In addition, these stainless steel anchor bolts are strong, durable, and reduce vandalism possibilities. They provide a stronger resistance when vandals try to pull units directly off pedestals. Use when vandalism is a concern. The anchor is manufactured with a stainless steel body and expansion clip. Nut and washer are included. Features a Tamper Resistant Removable Hex Heads Set. The tamper resistant removable head is added on top of the anchor bolt that reduces the risk of theft. The breakaway nut is installed with regular tools, including socket wrenches. Upon tightening, the tamper resistant removable (hex) nut heads shears off, leaving the 5/8” wide conical base to protect your property. Use these to reduce the risk of the unwanted removal of mailboxes and pedestals in public or private spaces. Also works to protect signs, lighting fixtures, and displays. Made from aluminum, these lightweight, corrosion resistant tools are nonmagnetic and great for wet environments. The tamper resistant removable nut (hex) heads will work on all ½” wedge, anchor, and L style bolts for wet concrete.
