The washers are permanently retained on the screw shank during manufacturing via a thread-rolling process, ensuring they cannot fall off during handling or installation.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eS-Type Double Washer\u003c\/strong\u003e configuration features both a \u003cstrong\u003estandard flat washer (STD)\u003c\/strong\u003e and a \u003cstrong\u003elock washer\u003c\/strong\u003e captivated together.
