Timcoloc Asphalt Anchor Bolt Fasteners allow contractors to attach steel protection barriers, noise barriers, and turnstiles or secure a steel plate to cover holes in a street while construction is in progress. They can also be used to stake tents or install banisters or railing in asphalt. The anchor bolts are made of carbon steel with a surface treatment of zinc aluminum flake that imparts higher corrosion resistance than hot dipped galvanized bolts. The bolts are available in 16mm x 100mm; 22 mm x 100mm; and 22mm x 155mm.
