SG2100 Hardware Sizes Needed

PopcornNMore · #1 (**permalink**) 04-26-2007, 08:30 PM

Does anyone know what the screw and washer sizes are for the SG2100 H-H motor drive?

I just repainted my SG2100 H-H motor drive and before installing I would like to replace all the hardware with stainless steel bolts and washers.

Went to Home Depot today and found that the following bolts, nuts and washers work really well with the SG2100 H-H motor drive:

QTY DESCRIPTION
4 Hex Bolt 8mm 1 25 x 20mm
(Used to attach motor to elevation bracket)
4 Hex Nut 8mm 1 25
(Used on U bracket)
4 Flat washer 10mm 10
(Used on U bracket)
4 Flat washer 8mm 8
(Used to attach motor to elevation bracket)

Home Depot didn't seem to have these available in stainless steel that I was looking for, but now since I know these sizes work well I can look for another source.

I'd leave the original washers on the elevation scales, since they have an indicator point on them. (at least on the version that Sadoun sells.)
I never understood the idea of switching to stainless steel hardware. I know hams do it with antennas since it makes it easier to get things apart if there is less corrosion (handy if you have to climb up a tower only to find bolts corroded together), but for something as cheap as one of these little motors, I'd think that the original hardware would long outlast the motor.

The washers on mine do not have elevation indicators. Galvanized bolts and washers are good, but stainless stell is even better.

This is the second time I painted my SG2100 H-H motor and it looks fantastic. In fact, it looks better today than the day I bought it several years ago. I wanted to replace the bolts, nuts and washers that had been rusting with new ones after the paint job.

What type of paint did you use? Painted both the dish and motor?

Lost my nut for the HH90 bolt when installing up on the chimney, need to do the same and go to Home Depot.... however mixing the bolt with a different type metal (dis-similar metal corrosion) is not a good idea... good to hear H.D. has a good nut-bolt selection.
