Externally threaded fasteners with coarse threaded shank and hexagonal washer faced head and a chamfered tip to facilitate mating with an internally threaded component.

Externally threaded high-strength, heavy hexagon structural bolts with a large head. These bolts are commonly used in construction and industrial applications mainly.

Externally threaded fasteners with fine threaded shank and hexagonal washer faced head and a chamfered tip to facilitate mating with an internally threaded component.

Externally threaded bolts having circular washer like flange under the head that increases the bearing surface to distribute the load when the bolt is fastened

Externally threaded hexagon socket head cap screws are cylindrical head screws with an internal hexagonal drive suited for a hex / Allen key or wrench. Used in smaller spaces

Externally fully threaded headless screws with flat or cone point and an internal hexagonal drive at one end and a flat surface at the other. Used in smaller spaces

Externally threaded headless bolts threaded all the way from one end to the other (full / all thread). They are designed for a nut to be applied on both ends

These feature a smooth, domed head that prevents adjustment from above. The square shoulder under the head resists rotation when the nut is tightened fully on the shaft. 

Externally threaded specialized fastener with a round head and a projection or "nib" (a small projection) on the bolt's shank to prevent turning during installation 

Externally threaded specialized fastener with a flat, countersunk head and a "nib" (a small projection) on the bolt's shank to prevent turning during installation.

Externally threaded cylindrical countersunk screws with a flare nose and a "nib" on the bolt's shank to prevent turning during installation

Externally threaded specialized fastener characterized by their U-shape and are typically made of steel. Commonly used in applications like pipe bridges
