Need some tough, rust-proof screws for a project? This pack of 20 stainless steel hex screws is a solid choice. They're size M5 (5mm thick) and 40mm long, with a classic hexagonal head (that's the six-sided one you use a spanner or socket on). They're made from A2 / V2A stainless steel, which means they're highly resistant to rust and corrosion – perfect for outdoor use, bikes, marine applications, or anywhere damp. They conform to the DIN 931 / ISO 4014 standard, so you know they're quality-made metric machine screws. The partial thread (with a smooth shaft section) is great for when you need to clamp materials together before the thread bites. Super versatile for DIY, model making, repairing furniture, assembling machinery, or general workshop use. Comes in a handy pack of 20. Just make sure you have the right size spanner (an 8mm usually fits an M5 hex head) to drive them in. Reliable fasteners from a brand focused on fixings.
