1. Locking performances?
Locks in any position independent of preload. Locking torques follow ISO 2320 which is
equivalent to IFI 100/107.
Lanfranco all metal locknuts perform in temperatures from -200oC to +400oC.
Ideally suited for corrosive environments, Lanfranco all metal locknuts are available in
stainless steel 304 and 316, A2-70 and A4-80, as well as steel nuts with augmented
corrosion resistance (600hrs to +1000hrs salt spray testing).
Lanfranco all metal slotted locknuts will not damage the male part nor will they seize
up upon installation or removal. This holds true even when dealing with stainless steel
as Lanfranco uses unique and permanent anti-galling treatments.
The majority of all Lanfranco made products are available from stock in either inch or metric
sizes in a variety of materials. Parts may be shipped from our North American or European
warehouse, or by one of our many worldwide distributors
