Metal Round Caps

More durable than plastic caps, these provide the most protection from abrasion and impact.

Domed Round Caps

The large domed head extends beyond the diameter of your pipe, rod, or tubing for added protection.

Heavy Duty Round Caps

Made of rigid plastic, these caps are more wear resistant than vinyl caps but not as flexible.

Round Caps

Slide these flexible vinyl caps on and they conform for a snug fit.

Sure-Grip Round Caps

A long, textured pull tab provides a sure grip for quick removal even when wearing gloves.

Tethered Round Caps

The tethered design allows frequent access to the ends of pipe, tubing, and other round objects without ever misplacing the cap.

Hanging Round Caps

Slide these caps over a tool handle or other round object and use the eye to hang it.

Roll-Resistant Round Caps

Commonly used on shipping tubes, these caps have a square head to prevent round objects from rolling during shipping and storage.

Conductive Round Caps

With a surface resistivity of less than 10⁵ ohms, these caps not only dissipate electrical charges, but can be used as an electrical shield.

Antistatic Round Caps

Keep equipment safe from electrical currents with these caps that have a surface resistivity of less than 10¹² ohms.

Chemical-Resistant Round Caps

These caps have excellent chemical resistance for masking parts during chemical finishing applications such as plating and anodizing.

Food Industry Round Caps

Made of FDA listed materials, these caps are suitable for food contact.

High-Temperature Round Caps

Good for electroplating, paint baking, and powder-coating applications, these caps withstand temperatures up to 440° F or 570° F.

Rectangular Caps

Slide these flexible vinyl caps onto rectangular objects and they conform for a snug fit.

Squeeze Top Caps

Squeeze the dome top to remove these caps. They're commonly used as thread protectors.

Heat-Shrink Round Caps

Permanently seal pipe, tubing, conduit, and even crimped electrical connections. Slide these flexible caps on and use a heat gun to tightly shrink them to the shape of whatever they are covering. Their outer surface shrinks while the inner wall flows into voids to create a sealed connection.

Fastener Caps

Screw Caps

Conceal and protect the tops of socket head or button head screws.

Hex Nut Caps

Sized to fit hex nuts, these caps snap on for a tight hold and provide protection from corrosion.

Hinged Fastener Caps

A one-piece hinged design allows frequent access to screw heads without misplacing the top. To conceal and protect the entire screw head, insert your screw through the hole in the base and flip the hinged top over.

Threaded Standoff Caps

Give open-ended standoffs a finished look and protect them from dirt and debris.

Snap-On Fastener Caps

To conceal and protect the entire screw head, insert your screw through the hole in the base and snap on the top.

Rebar Caps

Keep personnel safe from protruding rebar and pipe. Made of rigid plastic, these durable safety caps are bright orange or yellow for excellent visibility.

Locking Panel Plugs

The wings on these plugs expand against the sides of a hole to lock them in place.

Clear Locking Panel Plugs

These plugs are see-through to provide visibility and light transmission. They have wings that expand against the sides of the hole to lock them in place.

Vented Locking Panel Plugs

Vents in the top allow air circulation and permit heat and fumes to escape. All of these plugs have wings that expand against the sides of the hole to lock them in place.

Chimney Vent Caps

Cover chimneys to reduce downdrafts and prevent obstructions from entering.

18-8 Stainless Steel Socket Head Screws

Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.
