RS PRO Stainless Steel 1905 Piece Pozidriv Drive Screw/Bolt Kit

From the trusted RS PRO brand, this set of high-quality Pozidriv pan and countersunk machine screws are ideal for many applications. This set also includes washers and A4 nuts. Machine screws are used in pre-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. Machine screws are used to join many kinds of materials together, including wood, plastic and metal, making them suitable for use in many applications.

These machine screws are made from A4 stainless steel, which is often known as ’Marine Grade’ for its high hardness level and high resistance to wear & tear. These A4-grade Pozidriv machine screws are fully-threaded fasteners for reliable fixing, with correct sized nuts and washers supplied to ensure secure fixing.

In this kit, you will find 1905 pieces, including 635 washers in sizes M6, M5, M4 and M3 with accompanying A4 washers, and 275 full-thread countersunk machine screws with Pozidriv heads in sizes M5, M4 and M3 and lengths ranging from 6mm to 30mm, and 360 full-thread pan head machine screws with Pozidriv heads in sizes M6, M5, M4 and M3 and lengths ranging from 6mm to 20mm.
