Fixaball 1/2" Internal Shakeproof Washers Steel Self Colour

For locking threaded fastenings against movement and vibration, these Fixaball 1/2" internal shakeproof washers are made from steel with a self colour finish. The internal teeth grip within the fastening assembly while leaving a rounded outer edge.

Suitable for use where a more secure fixing is required, they also help prevent galvanic corrosion by insulating steel screws from aluminium surfaces.
