Some idiots forgot where they are... the ones that hold the brackets onto the bar and the bar onto the chassis..2ltr type 4.... Anyone know what sizes to pop down the hardware shop and get to save me spending 3.95 plus postage... each.. if I could even find them online! Sent from my Hudl 2 using Tapatalk
Mine were just a 13mm head long bolt with a shoulder on the ones to the chassis and a mix and match for the bar to brackets
I did just the same. Went a nut and bolt dealer . So cheap I recon would have got mote money back if I weighed them in for scrap
We're a bit used to being ripped off if it's labeled for an old vw.. Sent from my Hudl 2 using Tapatalk
They've made me feel so guilty and awkward with their penny prices I've offered to do the washing up and make em a cup of tea before now. I generally swap out to stainless too. Sent from my iPad using Tapatalk
Not scare mongering, but don't bolts that hold something heavy like that have to have some form of tensile strength? In biker world the amount of people that swap out high tensile steel for stainless is scary, Happy to be wrong!
You do need to be careful. Grade 8.8 bolts.. for these..an 8mm diameter bolt which in shear has 1tonne capacity, hangers have 4 then there's the gearbox hangers and the nose forks . Wouldn't trust unmarked bolts though! Hardware stores tend to sell proper ones as they supply building trade not just diy Sent from my Hudl 2 using Tapatalk
Knew this would come up. You're absolutely correct attention to use is very important, there were loads of horror stories of folk swapping fasteners out on MCs for Chinese colour anodised crap having engines shift and throwing chains etc. Being an aircraft engineer and a keen Motor Cyclist I always consider the reason for the fastener and forces applied to it. Good point well raised tho Sent from my iPhone using Tapatalk
The bolt gradings, ie, grade 8.8 is as follows: the first number, 8 is the Tensile Strength in this case minimum 800MPa whilst the second number is the Yield Strength, 8 in this case denotes the yield strength is 80% of tensile strength. ie a bolt grade 12.9 has nominal tensile strength 1200MPa and a yield strength of 1080MPa. There are tables around with Tensile, Yield, Shear and various other stress ratings (UK are the best as they are metric not US specs)
8.8s are fine. I'd be reluctant to buy them from DIY places when you can get them so cheaply from fastener places online, but if they're marked they should be ok. 8.8 is about Grade 5 Unified. It is folk who swap everything for stainless that get trouble.
