Bolt with a step and over 1,000 types of custom-made products available!

90% are custom-made products. We offer small lot support, material selection, cost reduction, strength enhancement, and suggestions for processing steps! Samples available. Prototyping available.

【Features】 We manufacture stepped bolts. For large production runs, we create molds for processing, but for smaller quantities, we produce them as shown in the photo by straight forging and machining the screw neck and rod tip. Since there are no mold costs, we can accommodate small lots. If you are considering stepped bolts, please feel free to contact us. We have produced them because the neck dimensions are not available in commercial products. The shaft diameter is 8 mm. If you have any issues with the neck dimensions or length dimensions, please feel free to contact us.
