1. Dimensions The M20 foundation bolt has a diameter of 20 mm and typically comes in various lengths, depending on the required application. The length can range from 50 mm to over 200 mm, and it’s essential to choose a length that suits the thickness of the material being anchored.

Rigid insulation nails are typically made of durable materials such as galvanized steel or stainless steel to ensure they can withstand the elements and provide long-lasting support for the insulation board. They are available in a variety of lengths to accommodate different thicknesses of insulation board and come with a washer or base plate to help distribute the weight of the insulation evenly and prevent it from pulling away from the substrate over time.

3. Versatile Use Galvanized Tek screws can be used in a wide range of applications, from roofing and siding installations to securing metal frames and structures. Their versatility makes them a go-to fastener in both residential and commercial projects.

Expanding metal wall anchors, often referred to as expansion anchors or toggle bolts, are hardware devices used to secure objects to walls or ceilings. They are constructed from metal and feature a unique design that allows them to expand within the wall when screw tension is applied. This expansion locks the anchor in place, providing a strong hold that can support significant weight.
