Grease Zerks

Metric Grease Zerks from Cottco Specialty Hardware are specifically designed for use with Weld On Bullet Hinges.

Featuring machined threads to ensure a proper seal is maintained when installed into the hinge. This coupled with a longer thread length than standard SAE dimensions produces a direct passage to the hinge barrel with no leakage. The brass housing secures a steel poppet and spring for long life operation.
