The Endurance Motorsport Bucket Seat M8 Bolt Pack (part m8-bolt-Pack) is a pack of standard steel M8 bolts for connecting bucket seat side mounts to FIA seat shells. It is the utilitarian option in the Endurance fastener range: no anodising, no Torx head, no weight saving. Just correct-grade steel M8 hardware.
The reason to keep a pack of these on hand is straightforward. Seat bolts see shock loading and are worth replacing if the car has been through a heavy off or if the bolts have been in and out multiple times. New hardware is cheap; a stripped thread in a seat shell is not.
If weight matters and your bolt count is small, the titanium alternative (m8-bolts-Titanium) is the upgrade. Grade 5 titanium at roughly 43% of the weight of steel, in seven anodised colours. For everyone else, these steel bolts do the same job at a fraction of the price.
