As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Black-oxide steel washers are mildly corrosion resistant in dry environments.

316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.

18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.

Zinc- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.

Aluminum washers are lightweight and corrosion resistant in wet environments.

Bronze washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.

Also known as high-collar lock washers, these have smaller outside diameters than standard split lock washers to fit neatly under socket head cap screws. As a screw is tightened, they flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Made of aluminosilicate that’s been chemically strengthened, this glass handles more wear and tear than other glass before scratching, cracking, or chipping. It’s often seen on mobile devices and enclosure display windows. This glass withstands drops without shattering from as high as two meters—twice that of standard aluminosilicate, often found as thermometer tubes. It’s also at least three times more resistant to scratching than standard aluminosilicate glass and significantly more so than most common glass. Compared to borosilicate and quartz, it’s harder and stiffer. It’s also more chemical resistant than borosilicate.

Because of how this glass is strengthened, it cannot be cut or trimmed without cracking or shattering. But, unlike glass that is strengthened through coatings, this glass remains optically clear and won’t distort objects. It also reduces glare.

Often seen on mobile devices, human-machine interfaces, and other frequently touched surfaces, this aluminosilicate glass has been chemically strengthened and treated to resist bacteria, mold, mildew, algae, and fungi. Gorilla® Glass 3 is harder and stiffer than borosilicate. It’s at least three times more resistant to scratching than standard aluminosilicate glass, often found as thermometer tubes, and significantly more so than most common glass. And it requires 150 times more weight to crack this glass than soda-lime glass, which is what most jars are made of. But because of how this glass is strengthened, it cannot be cut or trimmed without cracking or shattering.

While this glass doesn’t prevent the spread of viruses, its antimicrobial treatment does prevent the growth of 99.9% of bacteria. This treatment doesn’t change its clarity, unlike most coatings used to prevent bacteria on glass, so it remains optically clear and won’t distort objects.
