Fastening and Joining

Rounded Head Screws

Rounded Head Screws

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

Shoulder Screws

Shoulder Screws

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

Standoffs

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

Spacers

Unthreaded to create space between two surfaces or objects, often to align them

Lock Washers

Resist vibration to prevent fasteners from loosening

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Easy to tighten and loosen by hand for making frequent adjustments
