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.

Pin holes on the side of these caps let you insert an installation tool for increased leverage when tightening, making them difficult to remove.

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

Made of silicone, these caps withstand temperatures of 450° F for electroplating, paint-baking, and powder-coating applications. All of these flexible caps are tapered to fit a variety of unthreaded and threaded objects.

These metric nylon 6/6 cap nuts are chemical resistant, nonconductive, and lightweight.

These metric cap nuts have good chemical resistance and may be mildly magnetic.

These metric cap nuts have excellent resistance to chemicals and salt water.

These metric nuts are about half the strength of medium-strength steel cap nuts. Use them in light duty fastening applications, such as securing access panels.

These nuts are about 25% stronger than medium-strength steel cap nuts.

Brass cap nuts are corrosion resistant in wet environments and electrically conductive.

Known for their strength, these steel cap nuts have a black-oxide finish to resist corrosion in dry environments.

Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these cap nuts fit into tight spaces to cover and seal exposed threads in your food processing facility.

Low-profile cap nuts are about 20% shorter than standard cap nuts for use in low-profile applications.

The nylon cap covers and grips the threads to resist loosening.

An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts.

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

Keep a convenient selection of knobs on hand. To build a custom knob or thumb screw, pair one of these knobs with a socket head screw. They provide a secure grip to position, tighten, and hold fixtures, equipment, and machinery.

Use these knobs to display important messages. To build a custom knob or thumb screw, pair one of these knobs with a socket head screw. They provide a secure grip to position, tighten, and hold fixtures, equipment, and machinery.
