29541879 bolt-heavy flangedhex,class10.9 Allison spare parts

Allison 29541879 is a 10.9 grade heavy-duty flange hex bolt specifically designed for Allison transmissions. It is designed for high-strength locking parts such as transmission housings, main valve bodies, retarder assemblies, and clutch housings. It adopts the national/international standard 10.9 grade high strength standard, and the flange face has locking teeth to effectively prevent loosening under heavy load vibration. It is a core fastener for transmission overhaul and assembly of key parts.
This product is forged from high-quality alloy steel and heat-treated with tempering. It has high thread precision and uniform stress distribution. Even under high temperature, oil immersion and continuous vibration conditions, it still maintains excellent tensile and shear strength, and will not strip, break or loosen, ensuring the overall structure of the gearbox is stable and reliable.
