18-8 Stainless Steel Pan Head Phillips Screws
PTFE Coated
18-8 stainless steel pan head screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head. For partially threaded screws thread length may vary from the minimum thread length published to fully threaded.
PTFE-coated stainless steel screws won’t stick or bind as you thread them into a hole.

Stainless Steel Hex Screw and Nut Kits for Pipe Flanges
Stainless Steel with Blue PTFE-Coated Nuts
Use these kits to connect standard-size stainless steel pipe flanges for ANSI Class 150 or 300. They meet ASTM specifications for material quality, and the dimensions meet ASME specifications. Length of screws is measured from under the head.
316 stainless steel kits are more corrosion resistant than 18-8 stainless steel and have excellent resistance to chemicals and salt water. They may be mildly magnetic. Some kits have blue PTFE-coated nuts. This coating is slippery, chemical-resistant, and prevents galling. It also helps nuts thread smoothly.

Plastic Hex Head Screws
Fully Threaded
Plastic screws are chemical and oil resistant, nonconductive, and lightweight. Not recommended for high-strength fastening. Length is measured from under the head.
PTFE are our most corrosion-resistant plastic screws. They withstand salt water and acids, won't absorb moisture, and perform better than other plastic screws in extreme temperatures.
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.

18-8 Stainless Steel Phillips Flat Head Screws
PTFE Coated
Undercut Profile
Standard Profile
These screws have good chemical resistance and may be mildly magnetic. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
Screws with an undercut profile have a shallow head for use in thin materials.
PTFE-coated stainless steel screws won’t stick or bind as you thread them into a hole.
