Lightweight bolts made from aluminum, which has a specific gravity of one-third that of iron!
Aluminum bolts do not experience galvanic corrosion against aluminum, and since their specific gravity is 1/3 compared to steel, they are highly effective for weight reduction. The material specification is from the 7000 series, with a strength of 4T, and by applying anodizing treatment, high corrosion resistance and decorative qualities (various color variations) can be achieved. 【Features】 ■ No galvanic corrosion against aluminum ■ Significant weight reduction effect ■ High corrosion resistance and decorative qualities can be achieved through anodizing treatment *For more details, please refer to the catalog or feel free to contact us.

Company information
Our company's name was not always Topura since its inception; it was initially "Toyo Plus Screw Co., Ltd." Until then, screws primarily had slotted heads (minus), and the tools used for tightening were minus screwdrivers. Topura quickly adopted a cross hole (plus) in the head and became the first JIS-certified factory in Japan.
