The Alloy 904L Fasteners, ASTM A276 Type 904L Hex Bolt also have high yield and tensile strength due to the material they are made from. The minimum tensile strength of the 904L material is 490MPa which means it takes more than 490 MPa of force before breaking a fastener made up of the 904L material. The Stainless Steel 904L Bolts and Nuts, Stainless Steel 904L Flat Washer is one of the commonly used fasteners. It is used to fill in the gap between two components without damaging the components so the connection is still tight but the components themselves are not in touch with each other. We also produce different dimensions and types of bolts such as the SS 904L Hex Bolts. Please contact us for further inquiries and orders.
