RS PRO 281-978 Stainless Steel Slot Drive Machine Screw/Bolt Kit is a comprehensive set of 3168 high-quality machine screws, bolts, nuts, and washers made of A2 stainless steel, also known as 18-8 grade due to its 18% chromium and 8% nickel composition. This material ensures excellent hardness, wear resistance, and corrosion resistance ideal for challenging environments.
The kit includes slotted pan head and countersunk head machine screws ranging in size from 6mm shortest to 25mm longest length, conforming to DIN 85 and DIN 963 standards. Washers and nuts in sizes M2, M2.5, M3, M4, M5, and M6 meet DIN 125 and DIN 934 standards respectively, ensuring compatibility and durability in assembly applications.
These fully threaded machine screws provide superior fastening strength in drilled or tapped holes, enabling secure and reliable connections between components. The A2 stainless steel composition makes the fasteners generally non-magnetic and unsuitable for hardening by heat treatment, but provides excellent resistance to chemical and environmental effects.
The kit is organized and supplied in a sturdy polypropylene case with a hinged cover, supporting convenient storage and easy access to the 2,108 washer and nut pairs and 1,060 machine screws included.
Applications for this kit span industrial, chemical, food and drug manufacturing, bearing plates, heat exchanger tubes, pumps, and valves where corrosion resistance and mechanical strength are essential. The stainless steel ensures long service life even under exposure to water, chemicals, and moderate heat.
The kit contains 3168 pieces including screws, bolts, nuts, and washers. Manufactured from A2 stainless steel for corrosion and wear resistance. Machine screws have slotted pan and countersunk heads with full threading. Washers and nuts conform to DIN 125 and DIN 934 standards for quality fits.
