Fastening and Joining

Socket Head Screws

Socket Head Screws

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

Rounded Head Screws

Rounded Head Screws

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

Flat Head Screws

Flat Head Screws

Fit in countersunk holes for a flush finish that won't snag on surrounding parts

Shoulder Screws

Shoulder Screws

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

Set Screws

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

Captive Panel Screws

Captive Panel Screws

Secure panels and enclosures while still having access to them

Standoffs

Separate, position, or connect components in assemblies

L-Keys

Turn fasteners from either end and reach into tight spots

Screwdriver Bits

Pair with drivers to turn screws

Screwdrivers

Tighten and loosen screws

T-Handle Keys

To turn fasteners in hard-to-reach spots, there's a long shaft and a grip for your whole hand

Torque Screwdrivers

Torque Screwdrivers

Apply precise torque as you fasten screws to prevent overtightening

Fabricating and Machining

Fixture Clamps

Secure your workpiece to a fixture table so it won't move during machining
