RS PRO Steel Hex Socket Cap Screw, 4/40 x 1 1/4in

Introducing the range of RS PRO Socket Head Cap Screws, a high-quality fastener solution for applications where a secure finish and precise tolerances are required when joining two panels or surfaces used for machinery or clamping together. Each fastener is made from steel, making them much more cost-effective than their stainless-steel counterparts, while offering a high level of protection against surface rust and oxidisation.

Socket 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. Socket screws are most commonly used for:

• Carpentry construction like decking, railings and small frames


• Metalwork and metal framing


• Building work and construction


• DIY
