Countersinking Rivets Sheet Metal

Steel hardened steel low carbon steel and stainless steel give sheet metal screws long lasting durability.

Countersinking rivets sheet metal.

Countersinking is commonly used for holes that need to accept a flat head screw or fastener. Grainger offers a huge selection of sheet metal screws for your hvac and other metalwork projects. Indentation into sheet metal. Yardstore has a countersink for every application.

Select the head type and overall size you need in lengths ranging from 1 4 l to 4 l. Two countersinking ends for rivets carbide countersinks for rivets often used to cut hard and abrasive materials these carbide countersinks are harder stronger and more wear resistant than cobalt steel and high speed steel countersinks. We offer 3 different styles of countersinking which is shown below. The flat head lies flush against the workpiece.

Flat head types have flat surfaces that taper toward the screw body to allow for countersinking. Tinners solid rivets are a specialty rivet with a flat head. The primary type of fastener used in sheet metal construction is the rivet. Dimpling is substantially stronger than countersinking and should be performed on relatively thin panels.

Countersinking is done with a special bit attached to a drill on thicker metals 040 and thicker. Our aircraft countersinks have 1 4 x 28 threaded shanks. The next step is to countersink or dimple the metal if you are using countersunk rivets. Rivets are ideal for supporting shear and tensile loads as well as watertight applications.

The yardstore has a wide variety of steel countersink cutters for countersinking counterboring and spotfacing. Prepare sheet metal holes for flush rivet installation with precision with cutters for countersinking. Dimpling is the preferred method of accomplishing the recess over countersinking depending upon metal thickness. These rivets should fit securely in a recessed hole so they are flush with the surface of the metal.

Solid shank rivets are most commonly used in aircraft construction and they consist of a head known as the manufactured head and a shank. Steel is strong and durable but less corrosion resistant than stainless. An426 rivets require a 100 degree countersink. Countersinking ends for rivets carbide countersinks for rivets often used to cut hard and abrasive materials these carbide countersinks are harder stronger and more wear resistant than cobalt steel and high speed steel countersinks.

Rivets are the unsung heroes of the manufacturing industry. When placing an order or requesting a quote please specify the required dimensions based on the diagrams shown on the right side of the picture for each style. They are driven with a ball pein hammer and are used in sheet metal.
