Hex Head Screws

Hex Head Screws

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

Rounded Head Screws

Rounded Head Screws

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

Tapping Screws

Fasten a range of materials together without needing to tap the hole first

Socket Head Screws

Socket Head Screws

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

12-Point Screws

12 contact points handle more torque than a hex head while a flange eliminates the need for a washer
