Hexagonal Flange Screw

The Hexagonal Flange Screw is a highly efficient fastener that combines the convenience of a screw with the holding power of a washer. Designed with a built-in flange under the head, this screw distributes pressure over a larger area, providing greater load-bearing capability and reducing the risk of damage to the material being fastened. Made from durable materials, it offers excellent strength and corrosion resistance
