HULK screws were developed using state of the art technology and manufacturing methods. They work in perfect synergy with Infinity boards and were designed to do just that. For the best performance and longest lifespan of our products, we recommended HULK screws are used for all Infinity installations. HULK screws are an extremely durable and hard wearing choice for outdoor, corrosion-risk, or long term applications. HULK screws use an advanced bit lock system which maximizes torque transfer and extends the life of bits and screws. It also quickens assembly time.
