18-8 Stainless Steel Hex Head Machine Screws

Install these screws with a wrench or a screwdriver. Made from stainless steel, they have good corrosion resistance. A flange under the head means a separate washer is not necessary.

Stainless Steel Flanged
Hex Head Screws

Made from 18-8 stainless steel, these screws have good chemical resistance. A flange under the head distributes pressure over the surface, eliminating the need for a washer.

Extreme-Strength Stainless
Steel Flanged Hex Head Screws

For the strength of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength. The flange eliminates the need for a separate washer.

Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

18-8 Stainless Steel Heavy Hex Head
Screws for High-Pressure Applications

These Grade B8 screws are made from 18-8 stainless steel and have good chemical resistance. Also known as pressure bolts, they meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

Hex Head Screws with Flat Washer

A freely rotating but permanently attached washer distributes pressure over a wider area than a flange, preventing damage to your material's surface.

Stainless Steel Thread-Locking
Hex Head Screws

Made from 18-8 stainless steel, these screws have good chemical resistance. They have a thread locker to prevent loosening from vibration.

Sealing Hex Head Screws

An O-ring under the head prevents leaks and seals out contaminants.
