Made using M24 bolts! Starting with a 60mm underhead length, the tip tapers for 10mm. If you have any changes to the taper, tip fineness, size, etc., please contact me before purchasing. If you're happy with the item in the first photo, you can buy it immediately! About Custom Orders Please provide the following information: * Bolt size * Material (stainless steel, super high-tensile steel, etc.) * Underhead length * Finish * Quantity I will provide an estimate! Since I will order the bolts after purchase, it may take some time (about 2 weeks). Due to personal production, there may be some minor errors or small scratches during manufacturing. The bolts are heat-treated, and the heads are mirror-finished. (I am not responsible for any damage resulting from heat treatment.) There may be small scratches originally present on the bolts, so please understand that no claims will be accepted regarding polishing.
