Timco Galvanised Steel Dome Head Carriage Bolts & Hex Nuts (Silver) - M12 x 110mm (25 Pack Box) (12110CBG) These galvanised carriage bolts have a dome head for clamping timber to timber and the anti-spin shoulder means they are great at fixing ironmongery too. A hot dipped galvanised finish means that these carriage bolts can survive more than 500 hours of salt spray which is used to simulate exposure to wet conditions in moderately salty atmospheres. The anti spin shoulder which at the top of the shank makes sure that neither the bolt or the timber can slip once secured in place. A large flat head significantly reduces the chances of damage to to the substrate since the clamping force is distributed evenly across a wider surface area. Manufactured to DIN 934 and DIN 603 standards meaning you can be assured that these carriage bolts with hex nuts are of the highest quality.
