29541878 bolt-heavy flangedh Allison spare parts

Allison 29541878 bolt-heavyflangedhare high-strength fastening bolts specifically designed for Allison automatic transmissions. They are designed for transmission housings, main valve bodies, clutch housings, and heavy-duty load-bearing components. The integrated flange structure effectively improves the locking area and anti-loosening performance, making them an indispensable high-strength fastener in transmission assembly and overhaul.
This product is made of high-strength alloy steel and undergoes heat treatment and precision thread rolling process, resulting in excellent tensile strength and shear resistance. The flange face has anti-slip teeth, which prevents loosening, stripping, or breakage under heavy load vibration and high temperature oil immersion conditions, ensuring that the key components of the gearbox are firmly and reliably connected.
