What Is an M8 Copper Nut?
An M8 Copper Nut is a metric hexagonal lock nut with an 8mm diameter and 1.25mm coarse thread pitch, typically made from steel with a copper plating for enhanced heat and corrosion resistance. Often designed as a self-locking or flange nut, it resists loosening under vibration, making it ideal for securing brake pedals to chassis tubing or brake linkages, as seen in automotive and karting applications (e.g., exhaust manifolds or control systems). Its specifications, such as a 12mm or 13mm wrench size and 7.8-8.6mm height, ensure compatibility with standard M8 bolts, per sources like Bel-Metric and Wurth USA.
Why Use an M8 Copper Nut for Go Kart Brake Pedals?
The M8 copper nut provides secure fastening for brake pedals, critical for maintaining precise braking control under high-vibration conditions, a priority in your inquiries about pedal sets and foot pedal extensions (April 16-17, 2025). Its copper plating reduces corrosion in wet or dusty environments, while the locking mechanism (e.g., conical or pinch design) prevents loosening, ensuring safety during intense racing or off-road use. Compared to standard steel nuts, the copper-plated version offers better heat dissipation, ideal for brake systems near engines like Predator 212cc or IAME X30, and aligns with Luckyway’s focus on durable fasteners like their two-bolt cable clamps (April 13, 2025).
Designed for Durability and Compatibility
Luckyway Metal’s M8 Copper Nut is engineered for M8-1.25 coarse threads, fitting 1/2” to 1” chassis tubing mounts on brake pedals for brands like Tony Kart, OTK, CRG, and Yerf-Dog. Available as a hex lock nut or flange nut with a 12mm or 13mm hex size, it supports karts with #219 (7.95mm) or #428 (12.7mm) chains, 5” or 6” wheels, and engines from 150cc to 300cc. Its copper-plated steel construction ensures compatibility with high-vibration environments, reflecting Luckyway’s expertise in reliable components like wheel hubs and alloy rims (April 14, 2025).
Key Features of the M8 Copper Nut
The M8 Copper Nut, crafted by Luckyway Metal, combines robust materials, secure locking, and practical design, making it a top choice for go-kart brake pedal fastening. Here’s what makes it exceptional.
Copper-Plated Steel for Heat and Corrosion Resistance
Made from Class 8 or 10 steel (100,000-120,000 PSI tensile strength) with copper plating, the nut weighs ~0.02-0.03 lbs (e.g., 8.6mm height at 0.025 lbs). The copper finish provides 800-1,200 hours of corrosion resistance in wet or dusty conditions and withstands temperatures up to 300°C, ideal for brake pedal mounts near engines, as noted in IDParts.com’s exhaust nut specs. This durability mirrors Luckyway’s corrosion-resistant parts like sprocket guards (March 18, 2025).
Self-Locking or Flange Design for Vibration Resistance
Available as a conical lock nut (DIN 980V/ISO 10513) or flange nut (DIN 14440), it features a pinch or serrated design to resist loosening under vibration, critical for brake pedals on karts with Rotax Max or Briggs LO206 engines. The 12mm or 13mm hex size allows easy torquing (15-20 ft-lbs), ensuring a firm hold, as praised in Amazon reviews for exhaust applications and Luckyway’s precision fasteners (March 23, 2025).
Compact and Standardized Dimensions
With an M8-1.25 coarse thread, 7.8-8.6mm height, and 12mm or 13mm hex size, the nut fits standard M8 bolts used in brake pedal assemblies, per Wurth USA’s specs. Flange versions have a 17mm flange diameter for added stability, ideal for securing pedals to chassis tubing, aligning with Luckyway’s versatile components like two-bolt cable clamps (April 13, 2025).
Easy Installation with Standard Tools
The nut installs using a 12mm or 13mm wrench, torqued to 15-20 ft-lbs, ensuring a secure fit for brake pedal mounts on brands like Manco or Azusa. Its self-locking design simplifies maintenance, requiring no additional lock washers, making it user-friendly for pit crews or DIY builders, as seen in Luckyway’s easy-installation parts like pedal sets (April 16, 2025).
