18-8 Stainless Steel Socket Head Screws
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head.Silver-plated stainless steel screws have mild lubricity so they thread smoothly.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.
Screws that meet ASME B1.1, ASME B18.3, ISO 21269, and ISO 4762 (formerly DIN 912) comply with standards for dimensions. Screws that meet ASTM B456 and ASTM F837 comply with standards for materials.
