FAQ

Q: Can a bolt with light surface rust keep working?
A: It may be used temporarily if threads are intact. Replace it if seized, stretched or with rounded hex head.

Q: What causes thread stripping during tightening?
A: Over‑torque, worn threads, misaligned holes or insufficient strength. Stop tightening and fit a new bolt.

Q: Can ordinary low‑grade bolts be substituted?
A: Not recommended. Low‑strength fasteners tend to loosen or break under paving vibration.

Q: What are the installation requirements?
A: Clean asphalt and grit from threads, tighten progressively to correct torque and use anti‑loosening washers on high‑vibration locations.

Q: What faults follow bolt failure?
A: Loose components rattle; in severe cases, plates drop and interfere with feed chains and drive assemblies.
