1. Material Composition The “1% 201% 4%” typically indicates a specific ratio of metals used in the alloy, such as stainless steel or another corrosion-resistant material, which enhances durability. Stainless steel screws resist rust and corrosion, making them ideal for settings exposed to moisture or chemicals.

Self-drilling metal screws are essential fasteners widely used in construction, manufacturing, and automotive industries. Their unique design allows them to create their own hole in the material they're being driven into, eliminating the need for pre-drilling. This feature not only saves time but also enhances efficiency, making them a preferred choice for various applications.

Chemical anchor bolts utilize a resin-based adhesive to bond the bolt to the substrate, typically concrete. This method of anchoring offers several advantages over traditional mechanical anchors. The chemical bonding ensures a high load capacity and allows for a deeper embedment in concrete, which results in superior resistance to pull-out forces. Unlike mechanical anchors that rely solely on friction, chemical anchors distribute loads more evenly and significantly improve the overall performance of the fastening system.
