Using it

Do not return used product to the container.

The product helps develop greater and more uniform clamp load for the same applied torque. Use the K value of 0.18 (3/8 x 16 steel nuts and bolts) as a guide when setting torque, and check it for your own fasteners.

Storage and handling

Store unopened and dry at 8 °C to 21 °C. Storage below 8 °C or above 28 °C can adversely affect product properties.

Limits and safety

Not a high-speed load-carrying lubricant, and not for ball or roller bearings or parts where lubrication is critical. Not recommended for pure oxygen or oxygen-rich systems, or for chlorine or other strong oxidising materials. Read the safety data sheet before use.
