A spot on the threads.

My 510 has a serrated cup fan sheave setscrew with a nylon? plug(that red/black/... dot) that prevents the screw from working loose. I have noticed these 'nylock' type screws in later models(I do not recall ANY on my Goldie).

That is one of the setscrews that I recently purchased. I ordered it believing it was the setscrew buried under ackenpunky (sp) on the back side of the headstock (part of the quill feed assembly).

There is another which is part of the Motor Sheave Assembly. Neither of these are listed in quantity (5).

PS I got side tracked on the quantity (5) issue. That is the quantity in the help kit. However, coincidently, the Motor Pan is attached with quantity (5) screws. It was this coincidence that I got caught up in. Ref post #16 this thread.

Is nylock the proper terminology for what I have been referring to as nail polish?

Nylok is actually a registered trademark brand name of a manufacture that provides nylon patch (sprayed on nylon) and pellet (machined cavity in the fastener and inserted) products. http://www.nylok.com/

The other major competitor is ND Industries. http://www.ndindustries.com/

The generic name is nylon patch or pellet.

Think Frigidaire Dusty! I did misspell nylok! Nail polish = nylon patch.

This technology looks great. However, it doesn't look like anything I have seen in any of the Shopsmith items I have worked on.

The Nylok website causes me to believe the product is BLUE and it appears to be engineered into the fastener not dabbed on (like nail polish).

The original nylok was the 'plug' type. A hole in the side of the threads held a nylon 'plug' which protruded to about the od of the threads. What we are seing on the ss hardware is a 'cost reduced' replacement and is a 'blob' stuck onto the threads in one spot. The color can vary. I do not know if the color means anything. There are sealing type screws which are like a coating over most of the thread. The home page for ND shows that type.

In any event, the ss screws with the blob/patch/nail polish are intended to prevent the screw from coming loose when unintended. They require considerable extra torque to install them and remove them(the first time anyway).
