Stainless Steel Socket Head Screw DIN 912 Stainless Steel Screw Stainless Steel Allan Screw
Products Description
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head.
Black-oxide stainless steel screws have a matte-black finish. Silver-plated stainless steel screws have mild lubricity so they thread smoothly.Chrome-plated stainless steel screws have a decorative, mirror-like finish.
Metric screws are also known as A2 stainless steel screws.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
Screws that meet ISO 21269 and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
