Often used to fasten parts in engines and turbines, these are our strongest stainless steel screws. They are comparable in strength to alloy steel with the corrosion resistance of 18-8 stainless steel. Screws are nonmagnetic. Length is measured from under the head.

Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.

Screws that meet Fed. Spec. FF-S-86 and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
