Iv just bought stainless steel bolts and screws from Paddocs to cover pretty much the whole truck, but i was wondering if i should put any sort of anti corrosion stuff on them before putting them on ?
Any suggestions ? Thanks |

Duralac

The better companies who supply stainless bolts etc for 4x4 supply a sachet/small tube of anti corrosion paste from Wurth Brendan PS Information available HERE Last edited by leeds on 7th Dec 2011 10:00am. Edited 1 time in total |

On steel built cars you can use copperslip, but dont do that on our aluminium shells - building batteries does not solve problems! Go for TefGel, Weicon Anti Seize or anything related instead. BTW what does MOT tell you about stainless bolts? our German TÜV might be very unhappy /w stainless bolts on chassis carrying parts. Never forget: cars have owner, Landrover have field service personnel.

same here, you shouldn't use SS fastners on any stress or load bearing fastenings 2.4 90 XS 1968 1/32 scale Britains 109 Pick up. |

Stainless steel DOES rust and is not very strong, it's not necessary to use them. Use proper fasteners and cover with usual suspect potions if worried about rust!

ah, if only our friends at Land Rover would use proper fasteners in the first place...
Go retro and use sheradized fasteners...many of them were still fair on my Series 1 when I bought it - those were the days  1953 80

not strictly true Zag - you can buy different grades of stainless (as you'll know from your boating exploits) and when specifying stainless bolts you can specify ones which are actually stronger than 'ordinary' steel bolts - as always it's worth checking the application and buying accordingly. |

I'm confused now ! Zegato, are you suggesting that I do not use the stainless bolts fro
Paddocks to replace the rusted ones ??? |

S110 there is a large number of metals referred to as stainless steel. These are resistant to corrosion in different environments.
The two most common stainless bolts are referred to as A2 and A4 A2 is nominally resistant to corrosion in fresh water A4 is nominally resistant to corrosion in salt water and chemicals Common stainless bolts are referred to as A2-70 A2 meaning resistant to rusting in fresh water the 70 refers to strength and is 700 N/mm2 A standard mild steel bolt is marked 8.8. The first 8 refers to a strength of 800 N/mm2 whereas the .8 refers to stress at permanent set being 80% so ).8 x 800 = 640 N/mm2 Real High Tensile bolts are rated 12.9 12 refers to strength of 12 N/mm2 whereas the .9 refers to stress at permanent set being 90% or 1,080 N/mm2 That is the general reason why stainless bolts in high stress situations are not recommended.

Brendan knows the theory I only know that many advise not to use SS bolts on resto's/rebuilds due to strength/cost and they do rust anyway. Sheradised stuff is costly so most use the standard zinc coated fasteners, I bought ALL the correct size UNF fasteners for my rebuild for £110  and then you could use sheradised bolts if you want to for authenticity (although LR used a mix of bolts not just sheradised!) such as bumper bolts etc as they look nicer |
