RS PRO Zinc Plated Steel Round Head Self Tapping Screw, N°1/4-20 x 3in Long

Introducing the range of RS PRO Round Machine Screws, a high-quality, compact fastener solution for applications where a tidy and professional finish is required when joining two surfaces 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.

Machine screws are designed to be smaller and more compact than standard screws and can used with a wide range of materials like metal and plastic, 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. Machine screws are most commonly used for:

• Carpentry construction like decking, railings and small frames


• Metalwork and metal framing


• Building work and construction


• DIY
