Q: Are these compatible with concrete railroad ties?
A: Yes! Our rail anchor bolts work with both wood and prestressed concrete ties - use 1/4" thicker washers for concrete applications.
Q: What torque value should I apply?
A: Recommended torque: 450-500 lb-ft (610-680 N·m) for M24 track bolts. Always follow railroad maintenance manuals.
