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

Flat Head Screws

Flat Head Screws

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

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

Square Head Screws

Square Head Screws

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

Carriage Bolts

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

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

T-Bolts

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

Plow Bolts

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

Rounded Head Screws

Rounded Head Screws

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

Threaded Rods

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

Anchors

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

Single-End Studs

Single-End Studs

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

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Weld Nuts

Weld to metal surfaces to add permanent threads

Spring Plungers

Spring Plungers

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

Material Handling

Hoist Rings

Pivot to resist stress that would bend or break an eyebolt when lifting at an angle

Eyebolts

Route rope through the loop or attach hooks and shackles for lifting

Eye Nuts

Pair with bolts or threaded rod to lift and hang components

Wheel Axles

Connect rotating wheels and support vehicles

U-Bolts

Anchor heavy pipe, tube, and conduit; stronger than routing clamps and hangers

Routing Rings

Suspend wire and cable by feeding it through the eyehole

Fabricating and Machining

T-Slot Bolts

Secure clamps and workpieces to machine tables with quicker setup than a T-slot nut and stud

T-Slot Nuts

Combine with setup studs or bolts to mount fixtures to machine tables

Setup Studs

Secure setup clamps and fixtures to your machine table or assemble heavy machines

Fixture Kits

Everything needed to mount workpieces of different sizes to your machine table

Power Transmission

Rod Ends

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

Connecting Rods

Connecting Rods

Use with rod ends and swivel joints to link components in push/pull assemblies

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 Collars

Lead Screw Collars

Position components and limit travel along a lead screw
