ASTM A490 A325 DIN933 DIN931 4.8 5.8 8.8 10.9 Grade Black Oxide Heavy Hex Head Bolts

Bolts are threaded fasteners used to join or fasten two or more components together. They are commonly confused with screws, but they differ mainly in their design and application. A hex cap screw features a hexagonal head and is typically used in precision applications where tight tolerances are required. In contrast, hex bolts are often used in general industrial settings. The tighter tolerances of hex cap screws ensure a better fit in critical joints.
