Key Advantages

Aerotight is an all metal stiff nut - No vulnerable inserts to be affected by heat or oil.

Aerotight can be re-used many times - Self locking function will still remain effective having been used a number of times.

Aerotight will stay in position whether tightened down or not, provided the locking element is engaged - Does not have to achieve recommended torque to be effective.

Steel and Austenitic Stainless Steel Aerotight can be used up to a temperature of 300oC.

Aerotight can be supplied in all plated finishes if required.

Customised specials - Thin Aerotight or other specified thicknesses may be supplied in suitable volumes or could encompass different specifications of material. Larger diameters are available on request.

No additional parts are required for Aerotight to function, and therefore no special tools are needed for the application.
