Product Summary
Made from tough, lightweight nylon, these countersunk cross head bolts offer high tensile strength, wear resistance and impact resistance. Nylon is resistant to most organic solvents, fuels, oils, weak acids and bases, but strong acids and oxidising agents can degrade it. The countersunk head sits flush with the surface when fitted in a countersunk hole, and the cross head can be tightened with a cross head screwdriver. These fasteners are also known as plastic bolts or plastic screws.
