Agraffe

From Wikipedia, the free encyclopedia

An agraffe is a part found on some pianos. The agraffe is a guide at the tuning-pin end of the string, screwed into the plate, with holes through which the strings pass. It anchors the strings, ensures proper height and determines the speaking length of the string. Quality agraffes are usually made of solid brass but can be painted or plated steel.
