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.

High-Strength A286 Stainless Steel Button Head Torx Screws
A286 stainless steel screws have comparable strength to alloy steel with the corrosion and chemical resistance of 18-8 stainless steel. They have a Torx drive that has more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Length is measured from under the head.

Metric High-Strength A286 Stainless Steel Button Head Torx Screws
Made from A286 stainless steel, these screws provide the strength of alloy steel and the corrosion and chemical resistance of 18-8 stainless steel. They have a Torx drive that has more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Length is measured from under the head.
