About Aluminum

Carabiners—Not for Lifting

Screw-Locking Carabiners—Not for Lifting

Lock by screwing the latch into the body.

Twist-Locking Carabiners—Not for Lifting

To open, lift and twist the latch 90°.

Multiline Routing J-Hooks

Keep multiple bundles of wire and cable on separate hooks. The hooks have wide openings to allow access for installation, adjustment, and removal.

Weld-Mount Vibration-Damping Routing Clamps

For a more secure connection than rail- and adhesive-mount clamps, weld the bottom plate of these clamps onto your rails. They fit tightly around pressurized lines in hydraulic systems to lessen vibration.

Snug-Fit Vibration-Damping Loop Clamps

A molded cushion reduces vibration and wear from clamp edges, plus it provides a tighter fit around material than standard vibration-damping loop clamps.

Loop Clamps

These clamps completely surround single lines of pipe, tubing, and conduit while holding them close to the mounting surface.

U-Bolts

Mount these general purpose U-bolts into an existing bracket, or combine with a mounting plate for a secure hold at the mounting surface.

U-Bolt Mounting Plates

Add a mounting plate to your U-bolt for a more secure hold at the mounting surface.

Fasteners

Ring-Grip Quick-Release Pins

The smooth ring handle on these pins won't catch on parts. A spring-loaded, nonlocking retaining ball pops out when the pin is pushed through a hole, and retracts when the pin is pulled out.

Ring Shims

Precisely align, level, and adjust spacing on fasteners and shafts with these shims.

Peel-Away Layered Ring Shims

These shims are made of layers of metal bonded with adhesive. Remove layers with a utility knife until you get the thickness you need.

Metal Sealing Washers

Also known as crush washers, these compress when tightened to form a tighter, more durable seal than rubber washers. They are commonly used to seal fluids such as oil and fuel.

Metal-Bonded Sealing Washers

Create a stronger seal than metal or rubber alone. These one-piece washers are metal for strength with a bonded rubber seal that creates a tight grip.

Tag Rings

Loop these rings onto tags.

Locking Tag Rings

Choose from twisting, threading, cinching, and other locking mechanisms.

Control of Liquids, Gases, and Solids

Shower Curtain Hooks

Rings for Quick-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

Use these rings with quick-clamp high-vacuum fittings.

Clamps for Quick-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

Connect quick-clamp fittings in high-vacuum applications.

Multipurpose Aluminum

Multipurpose 6061 Aluminum Round Tubes

The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

Polished Multipurpose 6061 Aluminum Round Tubes

Polished on the outside to a #8 reflective, mirror-like finish, these tubes have no visible grain lines.

Anodized Multipurpose 6061 Aluminum Round Tubes

An anodized coating forms a bond to the inside, outside, and ends of these tubes to improve wear and corrosion resistance.

Multipurpose 6061 Aluminum Rectangular Tubes

Multipurpose 6061 Aluminum Hex Tubes

Architectural 6063 Aluminum Round Tubes

More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Anodized Architectural 6063 Aluminum Round Tubes

The outside of these tubes is anodized to improve wear and corrosion resistance.

Architectural 6063 Aluminum Rectangular Tubes

More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Corrosion-Resistant Aluminum

Easy-to-Form Marine-Grade 5086 Aluminum Tubes

5086 aluminum is used on ships, oil rigs, tanks, and pressure vessels because of its excellent saltwater resistance and formability.

Corrosion-Resistant 3003 Aluminum Tubes

3003 aluminum stands up to outdoor use, as well as exposure to chemicals. It offers a good combination of strength, formability, and weldability. It's often used for storage tanks, heat exchangers, and general sheet metal work.

Telescoping Corrosion-Resistant 3003 Aluminum Tubes

These tubes are sized so that each tube fits into the next larger size.

Easy-to-Weld 5052 Aluminum Tubes

Known for being one of the easiest types of aluminum to weld, 5052 is also recognized for its ability to resist salt water. It's widely used for the bodies of boats, buses, trucks, and trailers, as well as for chemical drums.

High-Strength 2024 Aluminum Tubes

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Building and Machinery Hardware

Fabric Grommets

Press these grommets into a hole you've already cut. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material.

Round Maintenance-Free Turntables

Also known as sleeve-bearing turntables or slewing-ring bearings.

Round Turntables

Locking Key Holders

Choose these holders if you need holders that each open with a different key.

Keyed Alike Locking Key Holders

Choose these holders if you need several holders that open with the same key.

Choose-a-Color Keyed Alike Locking Key Holders

These holders come in a variety of colors for easy key identification.

Shaft Collars

Set Screw Shaft Collars

Keep these shaft collars in place by tightening their set screw into the shaft.

Clamping Shaft Collars

These metal collars are stronger than plastic shaft collars.

Tight-Hold Quick-Release Clamping Shaft Collars

A threaded lever lets you tighten these collars with more torque than other quick-release styles, ensuring that they stay put on your shaft.

Quick-Release Clamping Shaft Collars

Installing and removing a collar is as easy as pushing down and lifting up a clamp lever.

Extra-Wide Clamping Shaft Collars

Wider than standard shaft collars with twice the number of clamping screws, these ensure a better grip for greater holding power.

Clamping Two-Piece Shaft Collars

These metal collars are stronger than plastic shaft collars.

Machinable-Bore Clamping Two-Piece Shaft Collars

Customize the bore of these collars to precisely fit your shaft.

Clamping Two-Piece Shaft Collars with Wrench Flats

Use a wrench to rotate your drive shaft without marring or gouging the shaft.

Inch-to-Metric Clamping Two-Piece Shaft Collars

Although these collars fit inch-sized shafts, they have a metric OD and width for use with metric equipment.

Quick-Release Two-Piece Clamping Shaft Collars

Make quick adjustments to these shaft collars with a lever on the side.

Flange-Mount Shaft Collars

Three tapped counterbored holes and three through-holes provide mounting flexibility.

Top-and-Bottom Mount Two-Piece Shaft Collars

Secure items to either side of these collars—each half has a flat end with a tapped hole

Top-and-Bottom Mount Shaft Collars

Mount these collars flush against each other or attach components to either side—the round body has flattened ends with tapped holes.

Quick-Release Shaft Collar Handles

These threaded handles take the place of a set screw, allowing you to move set screw shaft collars without additional tools—useful for when the collar serves as a stroke limiter or mounting clamp.

D-Profile Shaft Collars

To install, slide these one-piece collars onto the end of your shaft.
