Alloy Steel Socket Head Screws
With a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Length is measured from under the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.
Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing requirements for material quality.

316 Stainless Steel Shoulder Screws
More corrosion resistant than 18-8 stainless steel shoulder screws, these have excellent resistance to chemicals and salt water. They may be mildly magnetic. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components, and as an axle or pivot point.
Black-oxide stainless steel screws have a matte-black finish.

Stainless Steel Helical Inserts
Also known as Heli-Coil inserts, these inserts have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.
