All titanium bolts, nuts, and washers in the SPARTS Series are manufactured from premium "S"-grade TC4 titanium alloy. The bolt heads are forged using custom stamping dies at temperatures up to 650°C, and feature exclusive SPARTS markings.

To ensure maximum precision and consistency of the drive recess, each forging die is limited to no more than 300 production cycles. The fastener bodies are further processed using advanced manufacturing equipment, including precision turning, milling, and 3-axis CNC machining centers.

Surface treatments include PVD vacuum coating, matte anodizing, and mirror polishing, providing excellent durability while supporting a wide range of personalized color finishes with consistent appearance.
