The Linear 2400-433 is an OEM replacement split lock washer from the Linear 2400-series parts catalog. It measures 1/2 in nominal bolt size, standard split lock washer dimensions. Constructed from Spring steel with black finish coating. 1/2 in nominal size for standard 1/2 in fasteners. Helical split design provides spring action to resist vibration loosening. Sharp cut ends bite into fastener and mating surface for positive grip. Compatible with Linear SWG series gate operators and Linear SG series gate operators among other Linear gate operator series.
A: It is a 1/2 in split (helical spring) lock washer with a black finish, used to prevent fastener loosening from vibration in Linear gate operator assemblies.
A: The split in the washer creates two sharp ends that dig into the fastener and mating surface when the bolt is tightened, and the helical spring action resists rotational loosening under vibration.
A: Bc indicates a black coating applied to the washer for corrosion resistance and a uniform appearance matching other black-finish hardware in the Linear gate operator assembly.
A: It differs from the internal tooth star washer (2400-400 and 2400-421) in that it uses a single helical split rather than multiple teeth. It is simpler but generally provides less gripping surface than a star washer.
A: Use Linear OEM part 2400-433 or an equivalent 1/2 in split lock washer with black finish. Ensure the replacement matches the grade and spring temper for equivalent locking performance.
