RS PRO Zinc Plated Steel Hex Washer Head Self Tapping Screw, N°#4 x 1in Long

Introducing the range of RS PRO Sheet Metal Screws, a high-quality fastener solution for applications where a secure finish and precise tolerances are required when joining metal panels together. Each fastener is made from steel with a zinc coating, making them much more cost-effective than their stainless-steel counterparts, while offering a high level of protection against surface rust and oxidisation.

Self-drilling screws are designed to be used with a wide range of materials like wood and metal, and to join panels or pieces together. They offer a higher tensile strength than nails thanks to the thread which in turn produces a more secure fastening, making them ideal for medium to heavy duty applications. They are easy to install and can also be removed for disassembly or adjustment. Self-drilling screws are most commonly used for:

• Carpentry construction like decking, railings and small frames


• Metalwork and metal framing


• Building work and construction


• DIY
