A standard 13 mm wrench or socket is typically used for M8 hex nuts, though we recommend measuring your specific application to confirm the correct tool size before installation.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these copper-plated exhaust lock nuts suitable for turbocharged engines?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The copper plating is specifically chosen for high-temperature automotive applications such as turbocharger flanges and exhaust manifolds. The coating helps reduce galling on studs and makes future removal much easier compared to uncoated steel nuts.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between the 12-pack and 50-pack options?\u003c\/h4\u003e\n\u003cp\u003eA: Both packs contain the same M8 copper-plated exhaust lock nuts. The 12-piece pack is great for a single repair or small job, while the 50-piece pack offers better value for full engine builds, workshop stock, or multiple vehicle projects.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What size wrench is needed for these M8 copper-plated hex exhaust nuts?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"These M8 hex head exhaust lock nuts are approximately 17.4 × 9.2 mm.
