RS PRO Stainless Steel 3168 Piece Pozidriv 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. The A2 grade Pozidriv 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.
