This kit includes 12 precision-turned A2-70 stainless-steel studs and 12 flanged nuts designed for high corrosion resistance, consistent thread engagement, and predictable torque behavior. The studs feature split threaded lengths to accommodate different flange thicknesses and provide a secure hold for exhaust components.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the exact dimensions and thread details of these studs?\u003c\/h3\u003e\n\n\u003cp\u003eThese studs are specified as M10-1.25 x 48mm with distinct threaded sections and a hex nut size of 14mm. The overall stud length is 48mm, and the thread lengths are divided into 25mm and 15mm sections to suit various manifold flange designs. Use these measurements to confirm compatibility with your vehicle or replacement parts.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eStud specification: M10-1.25 thread pitch\u003c\/li\u003e\n  \u003cli\u003eOverall stud length: 48mm\u003c\/li\u003e\n  \u003cli\u003eThreaded sections: 25mm and 15mm lengths\u003c\/li\u003e\n  \u003cli\u003eNut wrench size: 14mm (hex)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the A2-70 stainless steel construction help in exhaust applications?\u003c\/h3\u003e\n\n\u003cp\u003eA2-70 stainless steel combines good corrosion resistance with reliable strength for under-hood and exhaust environments. It resists oxidation and surface rust better than plain steel, reducing the risk of seized studs and making future disassembly easier. This material choice is suitable for the thermal cycling and exposure typical in exhaust systems.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eMaterial: A2-70 stainless steel for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eDurability: engineered for repeated heat cycles\u003c\/li\u003e\n  \u003cli\u003eMaintenance: easier removal versus untreated fasteners\u003c\/li\u003e\n  \u003cli\u003ePrecision-made for consistent thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles and jobs is this 12-pair kit compatible with?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit is intended for various Toyota, Nissan, and Honda models — compatibility depends on engine\/manifold specifications. It suits exhaust manifold replacements, turbo flange reconstructions, and head-to-manifold fastening on engines using M10-1.25 studs of similar length. Always verify the vehicle’s stud length and thread pitch before installation.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCommon uses: exhaust manifold or turbo flange fastening\u003c\/li\u003e\n  \u003cli\u003eVehicle families: select Toyota, Nissan, Honda models (verify before purchase)\u003c\/li\u003e\n  \u003cli\u003eQuantity: 12 studs and 12 flanged nuts per kit\u003c\/li\u003e\n  \u003cli\u003eFit check: confirm M10-1.25 thread and 48mm length\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I install and torque these studs and nuts safely?\u003c\/h3\u003e\n\n\u003cp\u003eInstall studs by hand-threading into the head or manifold then tighten to the recommended torque for your engine using the 14mm nut size. Use anti-seize on the stud threads if desired, and follow vehicle-specific torque sequences to avoid warping.
