Tension-Indicating Hex Head Screws
Fully Threaded
Partially Threaded
An indicator dot changes from red to black when the screw is properly tightened. If it comes loose, the dot changes back to red. Also known as SmartBolts. Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. The zinc yellow-chromate plating provides corrosion resistance in wet environments. Length is measured from under the head.
