Hex Cap Screw Classification

Steel and stainless steel hex bolts are classified by grade for SAE or property class for metric.
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.
Class 4.6 4.8 5.8 Hex Cap Screws
Class 4.6 4.8 5.8 hexagon cap screws are made of mild or medium carbon steel.
Class 8.8 Hex Cap Screws
Class 8.8 hexagon cap screws are made from medium carbon steel and heat treated. Class 8.8 screws have greater tensile strength than classes 4.6, 4.8 and 5.8 hex bolts.
Class 10.9 Hex Cap Screws
Class 10.9 hexagon cap screws are made from medium carbon alloy steel and heat treated. Class 10.9 screws have greater tensile strength than Class 8.8 hexagon cap screws.
