SOLID RIVETS DIMENSIONS - FLAT, COUNTERSUNK, BUTTON, PAN, TRUSS, TINNERS, COOPERS AND BELT RIVETS

Solid Rivet Dimensions for flat head, flat countersunk head, button head, pan head, truss head, tinners, coopers and belt rivets are given in the following chart according to ANSI B18.1.1-1972 "Small Solid Rivets (7/16 Inch Nominal Diameter and Smaller)" standard. Small solid rivets are rivets with 7/16 inch nominal diameter and smaller.

Some important notes from the ANSI B18.1.1:

- Head dimensions given in this page are applicable to rivets produced by cold heading process.

- Rivets except countersunk head type shall be furnished with a definite fillet under the head. The radius of fillet shall not be larger than 10 % of max shank dia. or 0.03 inch, which is the smaller.

- Suitable Materials of solid rivets: Steel - ASTM Standard A31, Grade A, SAE J430, Grade 0, other materials - may also be made from stainless steel, brass, aluminum.

- Finish: Unless specified, rivets shall be supplied unplated or uncoated.

- Unless otherwise specified, rivets shall have plain sheared ends. Where requested by user, rivets with standard header points shall be provided.

- Designation: Nominal Size - Length - Type of Rivet - Material - Finish (if required). Ex: 1/4 x 1 1/4 Flat Head Small Solid Rivet; Zinc Plated, .125 x .500 Button Head Small Solid Rivet; Pointed, Aluminum.

Note 1: Dimensions are in inches.

Note 2: Sharp edged head. Maximum value is calculated on basic diameter of rivet and 92° angle extended to a sharp edge.

Note 3: Rounded or flat edged irregular shaped head.

Note 4: Head height is given for reference purposes only. Variations in head height are controlled by the head and shank diameters and angle of the head.

Note 5: Previously designated as a wagon box rivet.

Note 6: Size numbers in ounces and pounds refer to the approximate weight of 1000 rivets.

Note 7: Size number refers to the Stubs iron wire gage number of the stock used in the shank of the rivet.

Note 8: No standard tolerances for point dimensions are identified.

Note 9: Header points normally apply to these nominal shank lengths or shorter. The pointing of longer shank lengths may require machining to the dimensions specified.
