Bolt size

[paul_]

Hi lads, quick question for you.

I've just upgraded to a 1m Gibertini dish.
As I'm using the existing T&K brackets from my old dish, I'm just wondering if the existing rawl bolts are sufficient for the new load.

I'm currently using M6 which by my measurements are 2 inches in length and 5mm in diameter.

Is this sufficient?

what size is the hole in the brick

i use m8 = 10s with a 14 mm drill bit never had a dish or aerial come down yet in 25 years

[paul_]

12mm mate

It seems secure enough to be honest. The brackets are about 2 feet apart and the dish is between them.

cheers

[wod]

it will be fine as the gibertini dish is aluminium so nice and light

i use 7cm sleeve anchor bolts on mine

Cheers, you've put my mind at rest.

I didn't want to wake up to find the dish in the neighbours garden lol

Quite right......make him buy his own

I just purchased a 1.1m Triax Dish and Motor, they were mounted on a Heavy duty (2") 90deg long stand off (43cm) angle bracket.

It was fixed at the original owners with Rawlbolts without any problems.

I am fixing to a Brick Built house.

What size rawl bolts should I use?

[satelliteman]

8 x 60mm Drill Size 14 all day long.

Each to their own of course

Bricks may become softer due to aging. When I have to mount a bigger (larger than 60cm) dish to such walls, I prefer for making holes thru the whole wall, and adding support metal plate on back.

P.S. I personally have seen a situation, when wind broke off heads of M8 bolts, and took 150cm dish away.

[mick2me]

Read with horror reports of bolts shearing and dishes blowing off walls!

Instead of the angle bracked, I purchased TK Brackets.

Can anyone tell me what the maximum size of rawl bolt fits the holes on
a Standard TK Bracket. The max Diameter appears to be 10-12mm?

How does that compare to M8, M10 etc?
Might be obvious but...
are M10 rawlbolt a 10mm diameter thread?

[satelliteman]

M10's will fit though TK holes.

Just fit M8's or M10's, jobs a good'n

[CROSSBONES]

maybe a guide could be put up for different size bolts and the correct drill bit size`s needed.

I would like to know what size bit is needed for M10`s please mr satellite man

[Robbo]

It's 16mm Mr Crossbones.

I used some last week, similar to the ones Mr satelliteman has in his picture (except I have 10mm)

[mick2me]

I just Thought...

After giving the new TK Brackets a good coat of hamerite.

The stand off from wall to centre of support pole is 24cm.
Adequate for 1.1m Triax dish?

[rolfw]

Rawl Bolt hole sizes

M6 12mm
M8 14mm
M10 16mm
M12 20mm
M16 30mm

[Robbo]

Does you wall face exactly south?

Even if it does, it is going to be a bit tight, you should just get up to 45 degrees either way

[mick2me]

Thanks Robbo, the wall is within a couple of degrees of due south.

Would I need to go further than 45 E/W?

[Robbo]

It depends if you have line of site for that low an elevation. Never been past 45 degrees myself, so I don't know if its worth going that little bit extra.

[satelliteman]

If you have line of sight at such a low Elevation, there's a few good music channels on 53e which would be a good catch.

Thanks Mr Robbo Thats great as I have a 16mm bit in my tool box! And just bought 5 M10`s from Ebay for £4 inc del

[satelliteman]

Good price Mr. CROSSBONES as the M10's are not normally cheap

[Robbo]

That's expensive Mr satelliteman I paid £4.20 for 10, from a shop.

[satelliteman]

That's even better than screwfix Mr. Robbo71. It £6.32 for 10 (2 packs of 5)
