This is a super duralumin eyebolt W3/8 (1 piece). Eyebolts are necessary in various situations, such as tying a safety rope, securing luggage, or connecting stringers, so it's a good idea to have several on hand. However, standard W3/8 or M10 stainless steel eyebolts are large and heavy, and carrying multiple ones to the fishing spot can add a significant amount of weight. Duralumin eyebolts, on the other hand, weigh only about 9g and are very light, and the small, compact eye makes them easy to carry multiple pieces without taking up much space. Manufacturer: FMW ■ About the Material Made of super duralumin, a lightweight, high-strength material also used in aircraft. The specific gravity is only 2.8g/cm3, less than half that of stainless steel (7.93g/cm3), making it lightweight. Furthermore, the tensile strength is approximately 570N/mm2 for super duralumin, which is higher than the approximately 520N/mm2 for stainless steel. Each piece is produced by cutting from the material, which inevitably increases the cost, but it eliminates the risk of breakage because there are no welds. → #Other FMW products are here [For fishing for striped beakfish, longtooth grouper, giant grouper, bottom fishing, pitons, rod tips, rod holders]
