M5 X 10 Mushroom Head Roofing Bolts (With Square Nuts) Zinc

Roofing bolts are used in a wide range of construction projects to securely fasten materials to various structural elements, most commonly in roof construction to attach roofing sheets and panels to purlins and frames. They are also used for installing roof-mounted systems like solar panels and HVAC units, in timber and metal framework construction, and for various DIY projects such as garden structures. Their wide head distributes load effectively, making them ideal for thin or soft materials like sheet metal and wood.
