These RS PRO mushroom head bolts fasten thin metal sheeting or other materials to a roof. They have large flat heads that spread their holding force, ensuring a secure attachment that won't damage your materials, even when under stress.


As the bolts are zinc-plated, they're corrosion-resistant and won't rust when exposed to water. They come in a box of 100 bolts with nuts included, so you won't need any additional fixing components. You also won't need any specialised tools as you can use a standard Phillips head screwdriver to screw in the cross-top bolts.


You'll find these bolts used on construction sites or at home for roofing repair jobs. They're suitable for use in outdoor settings.
