One solid brass hinge pin for grand / baby grand piano top lid.  2 1/2" long overall fits an approximately 2" wide hinge, 3.81mm (.150") diameter, ball end, fits numerous pianos including Steinway, Baldwin and others.  Order two if you need a pair.

IMPORTANT: most manufacturers have used different sizes during different time periods. It is advisable to measure an existing pin (if available) or measure the inside diameter of the hinge where the pin is inserted. Please contact us if you need assistance in measuring your pins. If your pins are no longer with the hinge, we can help you determine which is the appropriate fit. 

I’ve been a piano technician 30+ years and am glad to help before or after the sale. My contact info is included with each shipment and you can also reach me through eBay.
