PTFE Flat Washer, ANSI, 5/16", 0.344" ID, 0.875" OD, 0.063" Thick (Pack of 100) Review

PTFE Flat Washer, ANSI, 5/16", 0.344" ID, 0.875" OD, 0.063" Thick (Pack of 100) Feature

• Flat washers are an economical choice when application requires spacer, shim, or other reinforcement
• PTFE is suitable for high-temperature environments and for applications that have the potential for surface wear and exposure to water and chemicals
• Meets ANSI specifications
• Size corresponds to matching screw or bolt size

Standard flat washers are an economical choice when your application calls for spacers, shims, or other reinforcements. PTFE material resists both low and high temperatures. Washer meets ANSI dimensional specifications. Color is white.

PTFE (polytetrafluoroethylene) has similar properties to Teflon, including an extremely low coefficient of friction (it doesn't stick to other materials and it resists surface wear). PTFE also exhibits a useful service life from below -100 degrees Fahrenheit, to temperatures of over 500 degrees Fahrenheit. Its resistance to solvents is also excellent throughout a wide range of temperatures. PTFE has a high dielectric strength (600 volts/millimeter), which makes it a good insulator. PTFE is also water resistant, absorbing less than 0.01% of its weight if exposed to water for a 24-hour period. PTFE has below average tensile strength, at 3000 psi (pounds per square inch).

Washers have a variety of purposes. They can distribute the load of a threaded fastener and can also be used as spacers, springs, shims, and locking devices. Washers can be measured in inches or in millimeters, and typically have an outer diameter about twice as large as the inner diameter.
