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

Rounded Head Screws

Rounded Head Screws

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

Plow Bolts

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

Set Screws

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

Carriage Bolts

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

Hex Nuts

Handle most general fastening needs

Flange Nuts

The flange distributes pressure, so you don't need a washer

Locknuts

Hold fasteners in place to prevent loosening from vibration

Tamper-Resistant Nuts

Tamper-Resistant Nuts

Hard to detach without special tools to prevent unwanted removal

Coupling Nuts

Connect and extend threaded rods

Easy to tighten and loosen by hand for making frequent adjustments

Cap Nuts

Cover and protect threads while adding a finished look; also known as acorn nuts

Square Nuts

Flat sides won’t spin in channels and square holes

Socket Nuts

Install in recessed holes and tight spots where a wrench won’t fit; also known as Allen nuts

Threaded Inserts

Threaded Inserts

Create new threads or repair stripped threads

Weld Nuts

Weld to metal surfaces to add permanent threads

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

Fabricating and Machining

C-Clamps

Temporarily secure workpieces together or to a work surface

Bar Clamps

Secure large materials with adjustable arms for even pressure distribution

Setup Studs

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

T-Slot Nuts

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

Lathe Chuck Jaw Nuts

Lathe Chuck Jaw Nuts

Secure jaws to a CNC lathe chuck

Material Handling

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

Hoist Rings

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

Rope Cleats

Temporarily secure rope

Routing Clamps

Secure routed lines of pipe, tubing, and conduit

Building and Machinery Hardware

Handle Nuts

Attach to threaded shafts to quickly turn the shafts by hand

Strut Channel Framing and Fittings

Strut Channel Framing and Fittings

Secure fittings in the U-shaped channel to route conduit and pipe or build other structures

Power Transmission

Rod Ends

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