RAYS Engineering Official Japan 17 Hex Racing Bolt Set - 48mm M14 x P1.5 (Neck Length 38mm / Black Plated) - 4 PCS PACK

Engineered for Premium European Performance Platforms Running Wide Tracks or Custom Spacers. Genuine Made-in-Japan SCM435 Chrome-Molybdenum Steel Extended Racing Lug Bolts Crafted by RAYS Japan. Upgrade and secure your European vehicle's wheel setup with the precision-engineered Original Rays 17 Hex Racing Bolt Set 48mm M14 x P1.5 Neck Length 38mm. Unlike standard configurations, European performance builds utilize heavy-duty wheel bolts that thread directly into the hub assembly. This official 4-piece racing pack from RAYS Engineering is forged from high-grade SCM 435 (Chrome-Molybdenum Steel), delivering exceptional structural fatigue resistance and the high tensile strength required for demanding street and track conditions. These racing bolts feature a durable Black Plated finish that complements premium dark or polished custom wheels while providing long-term corrosion defense. This specific setup provides a total length of 48mm paired with an extended 38mm neck length (under-head thread depth), making it excellent for wheels with thicker center faces or applications utilizing small slip-on wheel spacers. Designed around a compact 17 Hex profile, these bolts provide extra tool socket clearance inside narrow tuner lug wells to eliminate the risk of accidental scratches during installation. Each bolt is cleanly finished with contrasting RAYS branding to guarantee true Japanese authenticity.
