These black oxide hex head self-tapping screws with large washers are precision-engineered for automotive applications, delivering reliable and durable fastening solutions for all car brands. The integrated large washer distributes pressure evenly, preventing material damage and ensuring a secure, vibration-resistant hold—critical for automotive body panels, trim, and undercarriage components.

Made from high-quality carbon steel with a black oxide finish, they offer excellent corrosion resistance and a sleek, professional appearance that matches OEM standards. The self-tapping design eliminates the need for pre-drilling, enabling quick and efficient installation, while the hexagonal head ensures a firm grip with standard tools.

Bolts are packed in neutral packaging boxes with standard quantities arranged in small cartons. Custom packaging configurations are available upon request. Small cartons are consolidated into larger master cartons for secure transportation. Palletized units are wrapped with waterproof film and reinforced with packaging straps, with custom shipping marks available.
