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

Shoulder Screws

Shoulder Screws

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

Square Head Screws

Square Head Screws

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

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

Oval Head Screws

Oval Head Screws

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

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

Hold-Down Bolts

Hold-Down Bolts

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

Studs

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

Wood Screws

Fasten material to wood or pieces of wood to each other

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

Separate, position, or connect components in assemblies

Weld Nuts

Weld to metal surfaces to add permanent threads

Rivet Nuts

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

Binding Barrels

Binding Barrels

Create custom low-profile fasteners with binding barrel posts, caps, and screws

Spring Plungers

Spring Plungers

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

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Sockets

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

Power Transmission

Precision Lead Screws and Nuts

Precision Lead Screws and Nuts

Pair with a motor for accurate starts and stops in automated motion and positioning applications

Lead Screw Nuts

Lead Screw Nuts

Mate with lead screws to move components in a straight line

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 Elbows

Change the direction of flow when joining lengths of tube

Fabricating and Machining

Fixture Clamps

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