Inconel 718 Washers to Internal Tooth Lock Washers
Inconel 718 Internal Tooth Lock Washers, also known as toothed lock washers, are
engineered to
provide superior locking performance under extreme conditions. Manufactured by FERROBEND in India,
these precision plate stamped components are made from Alloy 718
(UNS N07718
2.4668 / NiCr19Fe19Nb5Mo3),
and offer excellent strength, corrosion resistance, and thermal stability. Available in metric and
inch sizes, they are widely used in high-temperature and high-vibration applications. These
washers conform to
ASTM B670,
ASTM A1014,
EN 10269 and ISO 6028 material
specifications.
Dimensional standards include
DIN 6797J,
ASME B18.22.1, ASME B18.21.2M, JIS B 1251, JIS B 1255,
SAE J489B, SAE J2655, and IFI 532, ensuring compatibility across global assemblies.
These internal tooth washers grip the mating surface to prevent loosening under dynamic loads. FERROBEND maintains ready inventory for domestic and export supply, offering fast turnaround and custom manufacturing upon request.
