The fasteners are used to adapt Thule accessories to fit ProSpeed Expedition Roof Racks. You replace the Thule T-Track bolts with our countersunk nut and bolt. The T-Track bolts supplied with Thule accessories are too wide to fit in our channel but our adapters work in the same way. 

To determine which ones you need for your accessory, measure the length of the T-Track bolts you have and order the correct quantity to replace them.
