Corrosion is a constant threat when working with fasteners on vehicles, bikes, and outdoor construction projects. Standard steel screws can seize, rust, and fail creating costly and time-consuming problems down the line. The Sealey S840S Set Screws are manufactured from Grade A2 stainless steel, which offers excellent resistance to corrosion, making them a reliable choice for automotive, cycle, and construction applications. Each screw conforms to DIN 933 and measures M8 x 40mm with a 1.25mm pitch, ensuring compatibility with standard M8 threaded applications. The pack contains 50 screws, providing good value for workshop use or trade jobs where multiple fixings are required. Once opened, the screws are stored in a resealable bag to keep them organised, prevent loss, and protect them from contamination between uses. With a nett weight of 0.90kg for the full pack, these are a practical, quality-assured fastening solution for professionals and enthusiasts working in environments where moisture and corrosion resistance matter most.
