RS PRO Stainless Steel 3168 Piece Slot Drive Screw/Bolt Kit

From the trusted RS PRO brand, this set of high-quality cross-recess pan and countersunk head machine screws are ideal for many applications. Machine screws are used in threaded holes, which can provide a stronger joint between the screw and the material it is driven into. This, combined with the full screw thread, will therefore translate to a higher quality finish and therefore a higher quality product overall.

These machine screws are made from A2 stainless steel, also known as 18.8 grade due to the 18% chromium and 8% nickel content, which provides a high hardness level and resistance to wear & tear. These A2 grade slotted machine screws are fully-threaded fasteners for reliable fixing with suitable sized nuts. The socket screws are used to join many kinds of materials together and are suitable for use in many environments.

In this kit, you will find 2,108 washer and nut pairs, in sizes M6, M5, M4, M3, M2.5 and M2, and 1,060 full-thread machine screws with pan or countersunk slotted heads in sizes M6, M5, M4, M3, M2.5 and M2.

The impressive strength of A2 stainless steels, especially grade 304, makes it a versatile component material that can withstand wear and tear. Its resistance to heat treatment means it can be used in environments where heat may be applied during production processes, such as welding and machining. Its corrosion resistance additionally makes it an excellent material for applications in which contact with food, fresh water, or chemicals must be tolerated by preventing reactions between substances and the components as well as ensuring a long product performance life.

Due to these attributes of grade 304 stainless steel, these machine screws are suitable for a wide range of applications, including:

• Chemical equipment


• Food & drug production equipment


• Bearing plates


• Heat Exchanger tubes


• Pumps & valves
