Alongside the power output，the weight of all racing machines is also a crucial aspect to consider.
These days the use of carbon fibre and aluminium is usual in the quest for weight reduction and even titanium is becoming more common.
Even though the total weight of every nut and bolt only represents a fraction of the machines total weight，if you wish to reduce it，every single gram saved counts！ With a weight advantage of up to 40％，when compared to common steel fixings，titanium produced screws and nuts provide the icing on the cake of any lightweight racing vehicle.
Due to the various anodised colours they are available in they are also more pleasing on the eye than normal fixings.
We now have a range of titanium nuts and bolts available in a large variety of forms and sizes and all are produced using a Ti-6Al-4V (grade 5) titanium alloy，normally used in the aerospace industry.
Besides its weight saving properties titanium is also highly corrosion resistant and stable at high temperatures.
The tensile strength of titanium bolts is，at around 950 N/mm²，about four times higher than stainless steel types.
This results in a tenacity rating for these titanium bolts of 10.9.
