Operating from the heart of Safat, Kuwait, Sayed Steel has built a reputation for providing industrial strength you can trust. As a dedicated manufacturer and supplier, we understand that the integrity of any structure hinges on the reliability of its smallest components. That’s why our Alloy Steel Grade 10.9 Washers are engineered with precision, offering unparalleled support for high-tensile fasteners in the most demanding environments, ensuring every connection is secure and built to last under immense pressure.
The exceptional strength of our Grade 10.9 Washers comes down to their carefully balanced composition and resulting mechanical properties. Crafted from a specific alloy blend, these washers are heat-treated to achieve a remarkable hardness and a minimum yield strength of 940 MPa. This meticulous process guarantees they will not deform or fracture under extreme loads, providing a dependable and rigid bearing surface that perfectly complements the high clamping force of Grade 10.9 bolts.
