Papua New Guinea Track Shoe Bolts Nuts (Universal) For Steel Track Of Crawlers (Excavator, Dozer, Loader...)
Bolts and nuts for steel track of crawlers are high-strength fasteners engineered to secure track shoes to links. These critical components must withstand immense vibration and shear forces, with specific sizes determined by machine weight and undercarriage requirements. Manufactured by Shengde Machinery (a 26-year factory), our fasteners feature hardened steel to ensure maximum grip and durability. Note: Please verify your thread diameter and length with us to ensure a 100% precision fit for your machinery.

Product Description
Steel track bolts and nuts for crawler machinery (excavators, bulldozers etc.) are high-strength, heat-treated fasteners, typically using Grade 12.9 alloy steel to withstand heavy impact and torque. They are generally sized based on the crawler's size, ranging from metric M12 to M36 and imperial 1/2" to 1-3/8".
Common Track Bolt and Nut Sizes:
- Mini Excavators (Small): Often use M12-M16 or 7/16" - 9/16" diameters.
- Mid-Size Excavators (e.g., PC200, CAT 320): Commonly use M20 x 1.5 or M18 x 1.5 thread pitches.
- Heavy Dozers (e.g., D6, D7, D8): Use larger fasteners like 3/4" (6V1792) or 7/8" (6V1723) and M20-M24.
- Track Shoe/Pad Bolt Lengths: Ranging from 35mm to 100mm+ depending on shoe grouser height.
Key Specifications:
- Grade: 12.9 (most common) or 10.9 (for specific applications).
- Thread Pitch: Usually fine thread for high tension (e.g., 1.5 mm for M20).
- Head Style: Domed/Oval head, plow bolt, or hexagonal head.
- Material: 40Cr or 42CrMo Alloy Steel.
- Common Part Numbers: 9W3619 (M20x55), 7H3596 (9/16"), 7H3598 (3/4").
