- I need a screw! (M7 Content)
Roofrack woes 🙁 Now I need to source an M7 Bolt/Screw.
Google and previous training seems to be telling me I need M7 Socket-Button/Socket-Cap/Allen-Head-Cap ones. Ideally stainless-steel. Sadly Google is not telling me where to buy them 🙁
B&Q and Screwfix have also let me down (they don’t do any M7 stuff apparently).
Ebay have regular steel ones for $999.99 (yes that is the genuine price and ‘people’ are watching the auction)
Help! Can anyone point me in the right direction?Posted 5 years agoandylMember
What make roof rack. You have to make sure you get the correct tensile grade. I remember Thule had a recall to replace some failing bolts a while back.Posted 5 years agoJamieMember
If it really is a M7, then SJS do a 20mm one.Posted 5 years ago
@Jamie – Yup, def M7. I was suprised as well, but managed to find a couple of M7 bolts that I thought would do the job. The thread is fine, but the head had to be ‘modified’ to make it fit and is a bit ‘string and sellotape’ so I need a better fix
@andyl – Worrying info as I know far to little about Tensile strength 🙁Posted 5 years ago
They are actually about 12-15mm long so I need to cut them down hence the preferance for stainless rather than coated/plated
As for the roofbar peeps, it was roofbox.co.uk who seem great/helpfull :-), but they are just a dealer so spares are an issue
Tensile strength is still making me ‘twitch’ though. Can you point me in the direction of any knowledge?Posted 5 years agofootflapsMember
Contact Thule with your woes about they’re great product they have a good history of customer service so may well send you some.
Not a very safe product though, the Thule bolts I had regularly snapped letting the bike carrier depart from the roof of the car and each time Thule just said ‘yes, it happens a lot’ and posted out a new bolt which then snapped a few months later….Posted 5 years ago
Hmmm more ideas/comments since last night. In summary
Its def M7. I borrowed some calipers and dug out my old engineers ref book and it is not 1/4″UNF
It’s a lease vehicle so drilling and tapping is not an option
It looks as if most of the ‘load’ is taken elsewhere, I ‘think’ these bolts are just there to stop the roofrack sliding round a bit so shear stregth is the most important bit
It’s not a Thule rack so they would not/could not help (although I do have 2 thule racks in the garage from previous cars so could try a blag, but the comment about thier bolts breaking above puts me off a bit…)
Looks like I need High Tensile bolts from a local company that I can ask questions (for such a small sale value as well, I already feel sorry for them)Posted 5 years ago
