18-8 Stainless Steel Hex Head Screws
Fully Threaded
Partially Threaded
The standard choice for fastening in wet and outdoor conditions. Made of 18-8 stainless steel, these screws resist corrosion from mild chemicals and water. These screws may be mildly magnetic. Length is measured from under the head.
Screws that are made in the U.S. are headed and threaded domestically using DFARS-compliant materials. Those that meet MS35307 or MS35308 adhere to military standards for material and construction; their dimensions also meet Fed. Spec. FF-S-85.
Match the thread spacing of mating components. 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.

Choose these screws for their adherence to strict military standards for material and construction. Dimensions meet Fed. Spec. FF-S-86 specifications. Screws may be mildly magnetic. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

High-Strength A286 Stainless Steel Socket Head Screws
Fully Threaded
Partially Threaded
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. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
Screws that meet Fed. Spec. FF-S-86 and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
