Nutsert Drill Size Chart

Nutserts are a threaded anchor point for bolting applications that are tubular fasteners.

They’re a permanent fixture that necessitates using a manual nutsert tool or an air/cordless nutsert gun.

They’re simple to install; simply insert the fastener into a pre-drilled or punched hole, and pull up to witness the nutsert body expand, compress, and lock into place.

It provides a permanent superior thread for the attachment of a bolt when the material is too thin or frail to support a bolt on its own.

In our guide, you can learn the nutsert sizes you need by using our nutsert hole size chart they recommend to meet your task. (Read Light Bulb Base Chart)

What Size Hole Do You Drill For A 5/16 Nutsert?

There are ten different thread size inputs, each with its own drill size, thickness, and other options.

It’s important to remember that the parent item’s thickness and substance determine the installation requirements.

To allow for 360-degree movement, all thicker materials will require larger holes.

When employing thinner metal, the situation may be similar or identical. Another crucial point is that the A-T series inserts are somewhat larger.

This is done to achieve a perfect fit at all times and to correct for thread shrinkage during the installation process.

All of the materials utilized in the A-T series are tin or cadmium-coated. This gives them a well-known appearance, but it also makes them appear identical at first glance.

What Size Hole Do I Drill For 1/4-20 Rivnut?

1/4-20 spline nuts made of aluminum. Body measurements: 0.350 “, measurements: 4″ x 0.355” Sizes of holes: 0.354 “-0.356 percent.

Now that you have your Rivnuts, test to ensure you drill a suitable size hole for a proper fit for the Rivnut.

The first thing to remember is that various providers make rivnuts to different specifications; thus, the hole size will change. If you bought Rivnuts from WA Fasteners, check the chart below to figure out what size hole you’ll need.

If the supplier does not have a chart, you can measure the outside diameter from the bottom of the head. (Read Lug Nut Socket Size Chart)

Note: Some Rivnuts are tapered. It’s essential to measure the largest section.

M6 Nutsert

What Size Hole Do I Drill For M6 Nutsert?

The thickness and density of the underlying product material required is important for the rivet nut installation hole size for your repair.

The larger the hole, the more 360° installation swaging is required.

The Auveco Thin Sheet Nutsert secures threads from one side of work in the material that is too thin to sustain threads.

The product can sustain heavy weight without vibrating or loosening in plastic, aluminum, mild steel, fiberglass, or other material regardless of hole size.

The tool-held Thin Sheet Nutsert is inserted into a prepared hole, and the tool pulls the threaded section until the fastener’s wall collapses radially outward, securing it to the sheet.

The tool is removed, revealing the Thin Sheet Nutsert for a bolt or screw. This entire repair process takes seconds, and anyone can do it.

The TSN will not break with a bearing surface attached to the TSN; the TSN will not break when the screw or bolt is tightened (head torqued off).

What Size Hole Do You Drill For A 3/8 Rivnut?

In addition, the A-T Series Knurled Threaded Insert can be placed in materials up to.030/76 mm thick.

The A-T Insert is swaged 360° into the sleeve and the hole. The A-T Insert can now be used with Grade 8/Metric 12.9 screws.

It is installed using lightweight, handheld pneumatic tools at any point in your product’s assembly chain.

The parent material’s density governs the size of the A-T SeriesTM Insert’s installation hole.

The larger the hole size in the material, the more 360° installation swaging is required before the rivnut is installed.

Note: Before specifying hole size, it is essential to test the application to ensure the recommended size can hold the materials, or if you need to change the size of rivnut to be installed. (Read Spark Plug Sockets Sizes)
