Galling is the welding of two mating parts due to excessive friction during fastening and screws made of stainless steel, aluminium, titanium or other alloys that self-generate an oxide film for corrosion protection, are susceptible to thread galling. Using CAMTRONIC and UNITRONIC materials, Unisteel has become one of the leading manufacturers with technologies to produce anti-galling fasteners for use in hard disk drive assembly and in applications where functional requirements exceed SUS 302 in terms of mechanical strength, high speed assembly, contamination and multiple service cycles.
