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

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

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

Tapping Screws

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

Set Screws

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

Tighten and loosen by hand without the need for tools

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

Elevator Bolts

Create a flush joint to allow movement in tight spaces such as grain elevators and belting systems

Hanger Bolts

Suspend pipe and other fixtures with wire or cable ties

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

Plow Bolts

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

Binding Barrels

Binding Barrels

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

Standoff Caps

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

Standoffs

Separate, position, or connect components in assemblies

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Threaded Rods

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

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

Anchors

Secure anything from signs to heavy machinery in concrete, brick, and drywall

Torque Screwdrivers

Torque Screwdrivers

Apply precise torque as you fasten screws to prevent overtightening

Torque Screwdriver Handles

Torque Screwdriver Handles

Pair with a shaft to create a custom torque screwdriver
