**Please note: These are not just a normal bolt. They are Hydrogen Embrittlement Resistant. (This is a corrosion inhibitor)
‘Hydrogen Embrittlement occurs when metals become brittle as a result of the introduction and diffusion of hydrogen into the material. The degree of embrittlement is influenced both by the amount of hydrogen absorbed and the microstructure of the material. Microstructures which bestow high strength, often monitored by hardness level, or having specific distributions of grain boundary particles or inclusions, can result in increased susceptibility to embrittlement. The phenomenon usually becomes significant when it leads to cracking. This happens when sufficient stress is applied to a hydrogen-embrittled object. Such stress states can be caused both by the presence of residual stresses, associated fabrication operations such as forming and welding, and applied service stresses. The severity of hydrogen embrittlement is a function of temperature: most metals are relatively immune to hydrogen embrittlement, above approximately 150°C.’

Just wanted to say thanks for the super fast service. Ordered my parts on Friday and they arrived on Monday. I live out west of Brisbane and normally never get things quickly. You have rekindled my faith in Australian suppliers! Have recommended your store to all of my Facebook friends and posted a good burst on the Australian Airheads Down under group on Facebook as well.
Hi, I just wanted to say thank you to all involved with my order. I received the items today. Great communication, fast shipping and quality products. I look forward to dealing with you again,
