The Big Bolt Size (And Pitch) Thread List Here
 

Ok... Seriously, We've all (or at least I have) Run into so many lost bolts, that I thought it might be helpful to create a thread that can be used as a resource to finding pitch threads quickly (if anyone has ever had to look them up).

Guys in?

I'll start off with something trivial:

Steering column knucles: Cotter M8x1.25

Wheel Studs: M12x1.50

S4 (S5?) N/A Exhaust Manifold: M10x1.25

Engine/Tranny (all but one): M14x1.25 [varying lengths]

P/S Rack Lines (two): M12x1.25
P/S Rack Lines (third, some models): M16x1.50 [impossible to find]

Oil Injectors (N/A): M10x1.00
Oil Injectors (TII): M10x1.25

S4 Shifter: M12x1.25
S5 Shifter: M10x1.25

Tie Rod Ends: M12x1.25

does anybody know the thread size and pitch of the engine mount bolts?

Brake caliper bleeders are 8m1. and 7m1 respectively. Also that clutch slaves are 8m1 or 7m1 depending on model.
N/A pilot bearing seal pn: 1881-11-404A (not sure if thats the universal mazda number though)

HA HA - I know what you mean.

I bag & tag everything, but still manage to loose bolts.

Best advice is not only to bag & tag as you pull stuff off the car, but pickup a thread measuring gauge (see pic below) and list the fastener/bolt specs in a chart like:

Front A arm mounting bolts: Qnty 2 - M10 x 14mm head, 18cm length, .25 pitch, - "8" strength stamped on top, built in washer

E.O.E.
 

hmmm, I believe the pitch is right but the diameterr should be 10mm (at least on my S5 N/A)

IS this a challange to see how many we can come up with! :D

How about the lower bolt on the starter, not the long one that goes throught the top.

This is for an S5 (Maybe S4 is the same?).

Some good info on here. I vote that after this thread has been filled with every single ;) bolt/thread size we get a compilation and archive. I've found bolts on the ground and didn't know what they were from... good job me :doh: .

The studs for the turbine housing to downpipe connection on an S5 turbo are M10x1.5 thread on both sides. The stud is 53mm long with a 10mm threaded end
for the housing side and an 18mm threaded end of the downpipe side.

what size is the stock coolant temp sensor?

anyone know the bolt size/thread pitch of the two bolts that hold on the s4 secondary fuel rail?

double

Can someone tell me the thread, pitch, and length for the brackets that mount the front anti-sway bar to the the frame rails please? 8? 10? 1.25? 1.50?

fix your S4 shifter info, its

S4 Shifter: M12x1.5

My S4 shifter fit just fine into a S5 tranny.

what shifters can the S4 shift knob fit to? what others use the m12x1.25?

As in other cars?

yeah, i know ( i think) nisans can fit S5 shifters..

(Edit...remove oversized sig...CHECK YOUR PMs)

Is this the bolts that attach it to the block or the ones that connect to the precat/midpipe?

I need the size and pitch of the bolts that connect the manifold to the precat (S5), because one of mine got stript...=noisy leak.

any info?

OK so I was under the car and checked it out, the studs that connect the manifold to the midpipe or precats is an M12-1.5

i say one person volunteer to take pm's from everyone and sort them in alpha order till we have them all.

Heck i'd be willing to do it, updated once a week, as long as someone could host it on there site

Derangedhermit - I believe that they're referring to the shifter's knob threads, not the fit into the trans. S4 and S5 knob threads are different.

I just realized I made a typo...the manifold studs are 12X1.25

.

Anyone know the size of the bolts that hold the seats onto the seat rails. (Not the ones that bolt to the floor, but the actualy seat rails) And the bolt that holds the handle on from the inside of the door? I know there are a long shot. Thanks

Can someone tell me the size/thread for the nuts that go on the stock TII spoiler?
The sides use the normal 10mm nut everything else has, but the pedestals are bigger.
I need to know the size for the pedestals.


My spoiler was broken and not on the car when I got it.
