【Success Story】Adoption in the Folding Bike Industry

-How the ultra-low head screw “310Slim” improved both design and productivity-

【1】Customer Profile

Industry: Japanese Hardware Startup Company
Application: Electric Folding Bike

A fast-growing Japanese hardware startup was developing a next-generation folding bike.
Their vision was to provide urban users with a product that combines space-saving storage and sleek design.
However, the fastening components in user-operated folding sections posed significant challenges.

【2】Challenges (Before)

Protruding screw heads interfered with folding operations and risked snagging hands or clothing.
Exposed screws compromised the premium look of the product.
Achieving a flush finish required countersinking, which added extra machining steps and cost.
Strict assembly precision was necessary, slowing down the manufacturing process.

【3】Proposal

We proposed adopting our ultra-low head screw “310Slim.”

Key Features:
Exceptionally thin head design eliminates interference during folding.
Blends seamlessly with the bike’s exterior for a refined aesthetic.
No need for countersinking, reducing production workload.
Maintains reliable fastening strength while supporting lightweight and compact designs.

【4】Results (After)

Eliminated the need for countersinking, simplifying the production process.
Improved operability, making folding smoother and safer for users.
Enhanced product aesthetics, achieving a more premium and stylish finish.
Boosted production efficiency and achieved significant cost reductions.
