Product Details

Spax® Black Screw, Countersunk Head with T Star, Fully Threaded (Product Part No: 018.00.656) is a premium choice for secure, professional-looking fastening on a wide range of projects. Designed for universal use, this Spax® Black Screw set combines clean aesthetics with reliable performance—ideal for decking, construction, cabinetry, and general carpentry work.

With a length of 40 mm and a thread diameter of Ø 4.0, these fully threaded screws bite firmly for dependable holding power. The countersunk head helps you achieve a flush, neat finish when installed correctly, making them a great option when appearance matters as much as strength. Whether you’re working with timber or timber-based materials, you’ll appreciate the smooth driving action and consistency through the job.

Driven by a T-Star / Torx (TS20) profile, the screws help reduce cam-out for better control and faster installation. The square tip and wave thread profile are engineered to reduce the gap effect and lower screw-in torque, helping the screw seat more effectively as you drive it home.

Featuring a black, zinc plated finish and made from steel, these screws are built for durability and long-lasting results. You’ll receive 200 pack screws, making it easy to stock up for multiple tasks or keep your site supply ready.
