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

Set Screws

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

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

Shoulder Screws

Shoulder Screws

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

Plow Bolts

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

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

Anchors

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

Fabricating and Machining

Setup Studs

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

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

Gear and Bearing Puller Forcing Screws

Gear and Bearing Puller Forcing Screws

Replace forcing screws on gear and bearing pullers

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

U-Bolts

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

Power Transmission

Rod Ends

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