RS PRO Button Socket Head Cap Screws


Introducing the range of RS PRO Button Socket Head Cap Screws, a high-quality fastener solution for applications where a secure and safe 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.

Features and Benefits:


  • This range of RS PRO fasteners is ideal for applications where a secure and safe final finish is required and is specifically used for joining machinery and parts together, or clamping with precise tolerances

  • Each fastener offers good lubricity to the threads of the fastener

  • In addition to this, the steel fasteners are much more cost effective than stainless steel and is also widely recyclable, making them a much more sustainable option

  • All sockets come in a plain finish, which is also known as furnace black. That means the parts are heat treated with the residual oils used in manufacturing heat treated into the surface for a black appearance.

  • Available in a wide range of sizes and drive types

Applications:


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
