Grade2 Hex Cap Screws
Grade2 hexagon cap screws are made of mild or medium carbon steel for non-critical applications that are not affected by extreme temperatures or stresses.
Grade5 Hex Cap Screws
Grade5 hexagon cap screws are made from medium carbon steel and heat-treated. They have a greater tensile strength than Grade2 screws.
Grade8 Hex Cap Screws
Grade8 hexagon cap screws are made from medium carbon steel and heat-treated. They have a greater tensile strength than a Grade5 screw, and designed for use in high stress applications.
Stainless Steel 18-8 & 316 Hex Cap Screws
Both 18-8 and stainless steel 316 hexagon cap screws are made from austenitic alloys. 18-8 stainless steel screws are used in products that require general atmospheric corrosion resistance. stainless steel 316 screws have a higher resistance to corrosion and have superior strength at high temperatures.
