NMFC 124640 - Metal Thread Grinding Machines | Class 92.5

To find the correct freight class for your shipment:

1. Secure the thread grinder to a robust skid: lag-bolt the base, add steel banding, lock the table and spindle, and crate loose tooling (wheels, dressers, guards) separately.
2. Protect precision components. Pad and cover ways, lead screws, and control cabinets; add corner protectors and a rigid top frame before stretch-wrap or shrink-wrap.
3. Mark center of gravity and lifting points, and maintain 4-way forklift access. Drain coolant where possible, cap lines, and use shock and tip indicators for high-value units.
4. On the BOL, state the full NMFC: Machines, metal thread grinding, in packages or on skids, NMFC 124640, Class 92.5. Add required accessorials (liftgate, appointment) up front.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Fixed Class 92.5 eliminates density math, speeding LTL quotes and rate comparisons for machine tool shipments.
• Correct NMFC and packaging minimize reclass and inspection charges, cutting unexpected costs and delays.
• Skid or crated protection lowers risk to spindles and controls, reducing claim frequency and downtime after delivery.
• Clear handling marks and accessorial planning shorten terminal dwell time and improve pickup and delivery success rates.
