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

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

Carriage Bolts

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

12-Point Screws

12-Point Screws

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

Tapping Screws

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

Square Head Screws

Square Head Screws

Turn the large flat sides with a wrench into square holes that stop further rotation

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

Plow Bolts

The head sits flush with countersunk holes while the bolt stays in place when tightening a nut

Tighten and loosen by hand without the need for tools

Hold-Down Bolts

Hold-Down Bolts

Hold material under the bent head while the other end is tightened down with a nut

T-Bolts

Turn by hand for easy fastening, use as a handle, or attach as a point for straps and clamps

Hanger Bolts

Suspend pipe and other fixtures with wire or cable ties

Wood Screws

Fasten material to wood or pieces of wood to each other

Oval Head Screws

Oval Head Screws

The domed top sits slightly above the surface of countersunk holes for a decorative look

Studs

Press, weld, or screw in place to add a threaded fastening point

Captive Panel Screws

Captive Panel Screws

Secure panels and enclosures while still having access to them

Threaded Rods

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

Single-End Studs

Single-End Studs

Use the unthreaded end as a pivot point, hinge, shaft, or locator pin

Standoff Caps

Create a finished look on standoffs and protect them from dirt and debris

Standoffs

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

Rivet Nuts

Add threads to thin panels with access from only one side; also known as blind inserts

Weld Nuts

Weld to metal surfaces to add permanent threads

Binding Barrels and Screws

Binding Barrels and Screws

Thread together for a low-profile fastener

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Spring Plungers

Spring Plungers

Apply accurate, consistent pressure for positioning, indexing, and ejecting parts

Sockets

Turn fasteners with an external drive style without slipping and damaging the drive

Power Transmission

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Ball Screw Nuts

Ball Screw Nuts

Internal ball bearings roll on ball screws for low friction when moving components

Rod Ends

Use with connecting rods to support loads and control steering, tensioning, or pivoting motion

Fluid Handling

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Fabricating and Machining

Fixture Clamps

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