Sirius 10.9 Grade Socket Countersunk Screws M4 20mm Pack of 1

These countersunk socket screws deliver exceptional holding power and a flush finish for professional-grade fastening. Manufactured to DIN 7991 and ISO 10642 standards, the M4 x 20mm size is ideal for applications where a smooth, unobtrusive surface is required, such as in machinery, automotive assemblies, or precision equipment. The high tensile Grade 10.9 rating ensures the screw can withstand substantial loads without shearing or stripping, giving you reliable performance in demanding environments. Each screw features a hexagon socket drive that provides excellent torque transfer and reduces the risk of cam-out, making installation straightforward with the correct Allen key. The countersunk head design allows the screw to sit flush with or below the surface of the material, eliminating protruding edges and creating a clean, professional appearance. Suitable for use in metal, plastic, and hardwood substrates, these screws offer versatility across multiple projects. The pack of one screw is convenient for small repairs, replacements, or when you only need a single high-strength fastener. Whether you are assembling furniture, securing components, or completing a bespoke fabrication, these socket screws combine strength with a low-profile finish for a durable, tidy result.
