Whats the thread pitch of the Harness mounting bolts pls?

[DirtBuddha]

Anyone know what the thread pitch is - as I need to order a set?  

Mine is a 2005 Imperial chassis car (1.6 K Series engine)

 

I have downloaded the Bolt List_Sizes_Torque values spreadsheet from the Files section on here... but there is no info about the thread pitch. See screen grab below of the relevant entries...

The Assembly Guide has 7/16" UNF x 1 3/4" bolts for the upper straps and 7/16" UNF x 1" bolts for the lap straps.

Please let me know if you'd like a copy.

As Jonathan says, standard seat belt bolts are 7/16" UNF, which is 20tpi...

Just as a reference, through international agreement all vehicles use 7/16"-20 UNF threaded bolts for all road certified vehicle seat belts and harnesses to avoid any mix-up on a safety critical area.

Wow - I love this place. I post what I thought was a fairly esoteric question and within 5 minutes people give lots of answers - BRILLIANT!  :-) 

 

@JonathanKay - yes please to the Assembly Guide. 

 

And does anyone have a more complete version of the 'bolt list_sizes_torque settings' that I found in the files section, as there are a fair few empty cells in it?

Please send me a Private Message with your email address.

The Bolt List, the Fastener Packs and the Assembly Guide cover most fasteners between them. Beyond that have you got a method of searching the archives that works for you?

PS: Thanks, James... another standards story and possible analogy to add my collection. Spent yesterday on priorities for data standards for the NHS in England!

Thanks Jonathan. I did do a search but it didn't produce any relevant results. In fact, usually when I search the search function just produces a load of irrelevant results (see example below...)

 

Following the link you posted I see there are 6 pages of disgruntled members comments about this. Any idea when we will get a real/useable search function? 

 

So these are the results from a search I just did about headlamp bracket bolt sizes....   quite what 'tyres' or 'X-Flow alternators' have to do with that search is anyone's guess, but there are no meaningful results from such a search.

 

 

[Jonathan Kay]

Let's do that search again together over in that dedicated thread.

Is there any way of removing the outside shoulder strap bolts without removing the roll cage? I have a "track day" roll cage with the double diagonal bars at the back. The bolts cannot be screwed out all the way because they are impeded by the diagonals.

[Jonathan Kay]

Once upon a time there was an addendum to the Assembly Guide describing which holes to use with which roll bar:

This discussion might be relevant.

Please could you add a photo of your arrangement.
