A hollow construction makes these plugs extra flexible, so they compress for easy installation and a snug fit. The tapered profile fits a range of hole diameters. If you flip the plug over, it can be used as a cap.

Polyethylene—Convenient and economical. Instead of cleaning and reusing, just toss and grab a new plug.

High-Temperature Silicone Rubber—Withstand multiple passes when paint baking, powder coating, and electroplating.

Pull-Tab-Release Hollow Plugs

Lift and pull the tabs with your fingers for easier removal than other plugs. With a tapered profile, these fit a range of diameters. Use to mask holes from coatings or protect threads during shipping.

Polyethylene—Convenient and economical. Instead of cleaning and reusing, just toss and grab a new plug.

Hollow Tapered Plug Assortments

Plug holes big and small. In addition to the hollow construction that compresses for a snug fit, these plugs have a tapered shape to fit a range of diameters. In a pinch, they can also be used as caps.

Polyethylene—Convenient and economical. Instead of cleaning and reusing, just toss and grab a new plug.

Thread-Masking Press-Fit Nuts for Sheet Metal

Shield internal threads from paint and debris during finishing processes. The removable rubber plug withstands high-temperature treatments such as powder coating. When you're ready to insert a screw, just push out the plug with a screwdriver or other tool.

Steel—Best for dry environments since moisture will cause these nuts to rust.
