RS PRO Stainless Steel 1830 Piece Slot Drive Screw/Bolt Kit

From the trusted RS PRO brand, this set of high-quality slotted pan and flat machine screws are ideal for many applications. This set also includes washers and nuts in corresponding sizes for the pan head screws.

Machine screws are driven into pre-threaded holes, which provide a stronger joint between the screw and the material it is driven into. This, combined with the full screw thread, translates 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 slotted machine screws are fully-threaded fasteners for reliable fixing.

In this kit, you will find 1830 pieces, including 714 washers in sizes M6, M5, M4 and M3 for the pan headed screws, 649 nuts, 247 slotted pan head screws in thread sizes M3, M4, M5 and M6 and lengths of 6mm, 10mm, 12mm, 16mm and 30mm, and 220 slotted flat head machine screws with slotted heads in sizes M3, M4, M5 and M6 and lengths of 6mm, 12mm, 16mm, and 20mm.

The impressive strength of A4 stainless steel, also known as ’Type 314’ or ’Marine Grade’, makes it a versatile component material that can withstand very high levels of wear and tear. A4 Stainless provides the highest level of corrosion resistance, making it an excellent material for applications in which there will be contact with food, fresh water, or chemicals, as well as surgical implants and even underwater installations.

Due to these attributes of Type 314 stainless steel, these machine screws are suitable for a wide range of applications, including:

• Chemical equipment


• Food & drug production equipment
