Stainless steel fasteners for general automotive applications often fall way down the pecking order from what is demanded by the aerospace, off-shore, nuclear and public transportation supply chains. In those safety critical industries each nut, bolt and washer comes with traceability and issues affecting fastening dissimilar materials together is well understood.
When I see stainless steel fastenings being sold to Joe Public in packs for their treasured and beloved vehicle (car, 4X4 or motorcycle) at a wide variety of prices, I do wonder if either the supplier or end customer has any real idea of what is being bought and sold. I'm sure that there are companies trading in this sector with integrity and backed up with solid technical expertise - but I'm also concerned that Joe Public can easily be sold 'mutton dressed as lamb'. Brendan has illustrated this point in his previous post - frightening thought "pass the grinder". Brendan kindly draws to our attention 3 excellent morals - just make sure that on No.3 the supplier knows his stainless from his stainless. As I tried to illustrate earlier - cheese is not just cheese, just as stainless steel fasteners vary widely. For those with an interest in stainless steel fasteners at the quality end of the market, here's a link to an English based company whose products I've become acquainted with over a long number of years. http://www.ssfast.co.uk/about.html |

Well TJ the Bah Humbug season is just about finish so I can return to being my normal grumpy miserly git of a self and carry on with my Yorkshire citizenship application.
![]() Now as already has been pointed out we are not charging enough so yes you can have one of the Nakatanenga VAST 110 minus the anti stick paste for the same price of the lesser 110 kits at £130 and you will get an extra 330 stainless parts FOC which seems to me to be a very fair offer ![]() ![]() I am no metallurgist but have seen some of the specification of the stainless steel used by Nakatanenda and they are on the list on the SSF website. Stainless bolts used for the attachment of lights and grilles to Defenders do not need the same traceability or quality control as bolts going into the nuclear or aerospace industry. We have seen some of the production plant at Nakatanenga and can ensure people that it is high quality and that they do understand stainless steel a lot better then I do. Brendan |

I like many people have no problem with vendors making a reasonable markup if they are selling a good product but i do object to paying over the odds !I have no knowledge of the quality of stainless steel fixings (except the quality of steel is graded)so i usually look for recomendations..........I am new to defender ownership and i am struck by the significant markup on many products.......one vendor advertising for ss 90 rear mud flap fixing bracket and asking fot £90 one vendor selling a steering boss and adding £40 to the price of an obviously rebranded item....Most sensible buyers can spot the chancers and the internet is your friend!I would take recomendations from here but i would always check the internet for other suppliers as there is always bias however unintentional if advice is provided by a vendor!

The ones I've bought previously are all stamped A2. Never seen anything different.

A4 (316)is the most corrosive resistant and the grade I come across more in the marine environment for exterior use, nevertheless the steel contains more chromium which makes it more brittle.
A2 (304)is fine and used prolifically in the automotive and other industries. ![]() Treat every day as if it is your last....one day you will be right!! |

When I used to be active doing research we had to have any published work refereed by 3 unknown independent acknowledged experts. With the internet anybody can 'publish' anything they like with little regard to the truth or being able to back up their claims. So treat the internet with extreme caution! Their is misinformation out their as well as good information. Vendors can be a valuable source of information, so use them wisely. Stainless steel is available in many different grades. A2 stainless is the common grade for stainless nuts and bolts, A4 is a marine grade stainless. The range of sizes of nuts and bolts in A4 grade stainless is not as common or as comprehensive as that available in A2. Specialised industries, such as the nuclear and chemical industries will have their own specifications for stainless nuts and bolts and their fastenings may well be specially made for them and yes their will be complete traceability for crucial components. However we do not require the same trace ability for stainless fittings holding on lights to a Defender. Nakatanenga has the Defender door bolts made with genuine heads in stainless steel plus the headlight adjuster screws as these are not available as off the shelf standard items. Brendan |

as im about to embark on re-building my defender onto a new galv chassis im going to be buying a lot of fasteners and want to go all stainless as the body is already mainly stainless (A2).
One of the things ive read is that certain bolts on the rolling chassis cant be SS because its not strong enough, do you chaps know which bolts these are? also things where the original bolt perhaps has a unthreaded shank and a plain SS bolt wont, will that kind of thing make a diff? about the only fine thread bolt ive come across on the body is the seat belt hanger so far! |
