the worthless word for the day is: zerk
[fr. Oscar U. Zerk, American inventor]
/zerk/ a grease fitting
"A zerk is a grease fitting on a machine,
a sort of hollow nipple, over which a grease
gun is fit, and through which grease is
applied to moving parts... Oscar U. Zerk
was born in Austria but lived in the United
States. In the 1920's, while working for
the Alamite Corporation, he invented the
Zerk fitting. He died in 1968 ... and
probably slid effortlessly into his coffin."

"The beefy arms themselves are thick, rounded
heavy-duty shafts made of 1 ¼-inch heavy-wall
DOM tubing, are zinc-plated and come with zerk
fittings and Grade 8 mounting bolts."
