Product Detail

description

This genuine M20×140 bolt is made of premium alloy steel and strengthened by quenching and tempering. Rolled threads feature full, continuous tooth profile with outstanding tensile, fatigue and shear resistance, suited for sustained heavy vibration of pavers. Standard thread size mates well with M20 nuts and washers for reliable engagement and low risk of thread stripping. This bolt secures thick supporting assemblies during paving. Elongated shank, damaged threads, worn bolt heads or cracks will loosen load‑bearing brackets and trigger vibration and abnormal noise, even structural failure. Inspect each bolt during feeding assembly overhaul and replace damaged units.

product parameters

Applicable Scenarios

Fastening large feeding supports and drive bases of pavers; connection of thick welded brackets; assembly of multi‑layer heavy components; replacement during overhaul of heavy‑load feeding points; pre‑assembly of thick supporting structures on new machines.

advantage

- Original standard threads with precise dimensions mesh smoothly with matching nuts and resist stripping
- Quenched and tempered high‑strength shank provides reliable tensile and impact resistance for long‑term heavy vibration
- Anti‑rust surface coating protects against muddy water and asphalt dust on construction sites
- Sufficient shank length fits stacked thick welded parts with proper assembly margin
- Ideal for critical load‑bearing positions, delivering stable clamping and lowering failure risk from loose brackets

FAQ

Q: Can removed heavy‑load bolts be reused if they look intact?
A: Reuse is not recommended. Heavy‑duty bolts develop invisible internal fatigue after loading and may fracture suddenly. Replace them during overhaul.

Q: What should be noticed when installing this long bolt?
A: Clean thread debris and align holes before fitting. Never drive it by force. Tighten to specified torque and use washers as required to avoid insufficient or excessive preload.

Q: Can M20 bolts of different lengths substitute each other?
A: No. Use the correct length. Too short leads to insufficient thread engagement, while excessive length causes interference with nearby parts.

Q: How to deal with recurring loosening of heavy‑load bolts?
A: Check flatness of mating surfaces, remove asphalt residue, fit lock washers, torque correctly and carry out periodic retightening inspection.
