A medium viscosity, medium strength, screw and threadlocker. Capable of bonding “As Received” parts covered with a light film of oil. Non-drip consistency for clean, economic application.

Used as a locking compound for direct application to lightly oiled components. Replaces spring washers and lock nuts. Allows for disassembly using the correct tools. Also prevents rusting or corrosion.

Ideal for rebuilding engines where by some parts are being recycled/cleaned up, versus all brand new parts where by Bond It A70 can also be used for application. (A70 requires no oil residues present, ie only new parts. where as A43 here will work with slightly oiled parts, ie a sump bolts/plug but also new pre oiled parts.


Remove heavy oil and grease contamination. Best results are obtained on clean parts.

At the least a good wipe with dry tissue is required!
