Also known as 'Cup Square Hex Bolts', the square underneath the Cup stops rotation of the bolt when tightening. Conform to DIN 603 and DIN 934 standards. Available in a comprehensive range of sizes to suit most applications. APPLICATIONUsed mainly for fastening timber to timber and is extensively used for timber joist construction in house building and numerous decking applications. A Carriage Bolt, also known as a Coach Bolt or as a ‘Fully Threaded Cup Square Hex Boltâ€, has a domed or countersunk head, and the shank is topped by a short square section under the head. The square section grips into the part being fixed (typically wood), preventing the bolt from turning when the nut is tightened. A rib neck Carriage Bolt has several longitudinal ribs instead of the square section, to grip into a metal part being fixed. Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrateâ€s surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers.Carriage Bolt & Nut ZP M6 x 100 Bag 10 Carriage Bolt & Nut ZP M6 x 100mm Bag 10

The description says they are stainless. They clearly aren't. They stick to a magnet and are zinc plated. It also says they are Class 10.9 but the packaging says nothing about class and the bolts have no markings on them. I too bought them to adapt Thule J hook kayak racks to the fatter Thule "Pro" bars but am a little concerned about using longer bolts that could be weaker than the originals. Such a misleading description.

They’re bolts and nuts. They seem as described and do the trick.

100 mm is about 4 inches about an inch longer than the carriage both that came with my Thule carrier that rusted. The longer bolts accommodate a thicker roof rail that I

I needed these bolts to extend a Thule accessory around a larger cross bar. There are very few places to purchase this length in the M6 size (probably because Tucker Carlson foolishly thinks the metric system will ruin the US) but this is precisely what I needed and worked perfectly! Thanks for offering this bolt length option!
