Modular Synth Panels

I bought a bag of 1000 screws years ago from:

These look identical to the screws supplied with MOTM modules, but are  
shorter so that they work with flat rails mounted on a wood frame. The  
blackness never wears off. The part I ordered is:

Item Name: Qty. 1000-#8-32 x 1/4 Machine Screws, Phillips, Pan, Steel,  
Black, Full Thread

Just noticed that prices have doubled since I ordered mine. Shipping  
may turn out to cost more than the screws themselves, depends on how  
many you buy.
