Product Description

Emergency handling

If you encounter rust on the Flange Head 12 Point Cap Screw during use, do not panic. Here are the emergency handling methods for when the product shows signs of rust.

（1）Mild rust (surface rust)

Wipe with rust remover (such as WD-40), or use non-metallic brushes (copper brushes, nylon brushes) to remove it, and then reapply anti-rust oil.

（2）Moderate rusting (rust pit depth < 0.2mm)

Determine whether it affects the bearing capacity of the Flange Head 12 Point Cap Screw. If it is not a critical part, the rust can be removed and the bolts can be used at a reduced grade; for critical parts, it is recommended to replace them with new ones.

（3）Severe rusting (large area of coating detachment, rust pits > 0.5mm)

Directly scrap it, replace with a new one, and do not use it.

（4）If the packaging is found to be damaged:

Replace the old VCI rust-proof bags immediately and add desiccants.

Check if the internal products have been dampened. If necessary, reapply the oil.
