Kenneth Beesley
Dear Group, I have a milling attachment 827NK1 for my SB 10k lathe, but it’s missing the two bolts shown in the following photo. If some kind soul could identify for me the dimensions of these bolts (diameter of shaft, length of shaft, and thread pitch) I would be most grateful. Best wishes to all, Ken ******************************* Kenneth R. Beesley, D.Phil. PO Box 540475 North Salt Lake UT 84054 USA

I have one of those. I’ll dig it out and see if it has the bolts.

On the SB milling attachment for my 9C, those two bolts are 5/16 x 1.25, coarse thread.

I don't know the part number for my attachment. The width of the "vise" is 3", and the opening is about 1.125", with the insert removed. The two bolts are spaced 1.625".

+1 on what David said. If I did all my checking correctly, South
Bend part# is 112x120, which is a commercially available 5/16-18 x
1-1/4" hex head cap screw. Thanks, George H. Meinschein, P.E.

Thanks for the additional information, George. Your response reminded me that there are a host of options at the hardware store, and that the original bolts are unplated, uncoated, plain steel hex head cap screws. The washers--I have fair reason to believe mine are original--are also not plated and are of modest thickness. In general, I have a preference for socket head cap screws and thick, precision washers. While I won't replace the bolts on my milling attachment, since they are in good condition, were some elf to make off with them, I'd yield to my preference. Dave David W. Pennington Denver, Colorado 720-442-3744 - Please note the new number.
