RHI Automotive 8355-Z Zinc Open End Acorn Bulge Lug Nut Kit 5-Lug

The RHI Automotive 8355-Z is a zinc-finish open-end acorn bulge lug nut wheel installation kit designed for 5-lug applications. Built to meet and exceed OEM standards, these lug nuts are an ideal upgrade for factory or aftermarket wheels requiring dependable fastener performance and long-lasting corrosion resistance.

AntiWear 18-Point Contact Technology:

Unlike conventional 6-point acorn lug nuts, RHI's unique 18-point contact design delivers three times the contact area. This dramatically improves torque distribution during installation and significantly reduces the risk of stripping, rounding, or chipping lug corners over time.

Key Features:

• Zinc finish — durable, corrosion-resistant plating suited for everyday driving conditions
• Open-end acorn bulge design — cone seat seating style for use with factory and aftermarket wheels
• 5-lug kit — includes lug nuts and 1 installation key
• 1045 carbon steel construction — cold forged and heat treated to 10.9 grade hardness for superior strength
• Neoshield coating — proprietary aerospace-grade nanotechnology coating fused to the surface, virtually eliminating porosity for a smoother, shinier, and more durable finish
• 300+ hour salt spray tested — engineered to resist rust and corrosion under demanding conditions
• Two-piece construction — delivers more usable thread engagement versus traditional one-piece designs
• 2-year limited warranty — backed by RHI's manufacturer warranty against defects in materials and workmanship

Installation is straightforward with basic hand tools. Always torque to manufacturer specifications and re-check torque after initial use for best results.
