Fastening and Joining

Hex Head Screws

Hex Head Screws

Used with nuts to create a stronger joint than flat and rounded screws

Socket Head Screws

Socket Head Screws

With a deeper drive than flat and rounded head screws, these withstand more torque for a tighter hold

Flat Head Screws

Flat Head Screws

Fit in countersunk holes for a flush finish

Set Screws

Exert pressure at the tip to hold parts in place, unlike screws that hold material together with threads

Shoulder Screws

Shoulder Screws

Rotate parts around the cylinder under the head to guide and align them during installation

Rounded Head Screws

Rounded Head Screws

Sit just above the surface for a low-profile finish and hold tighter than flat head screws

Carriage Bolts

A smooth head provides a finished look while a square neck keeps the bolt in place when using a nut

Wood Screws

Fasten material to wood or pieces of wood to each other

Standoffs

Threaded to separate or connect parts as well as position components in assemblies

Threaded Rods

Anchor, connect, or hang components in a wide variety of applications
