Blind rivets are indeed sized primarily based on body diameter and grip. The body diameter refers to the diameter of the rivet shaft, which is crucial for ensuring the rivet fits properly in the hole it's intended for. The grip refers to the total thickness of the materials that the rivet will be joining together. This dimension is vital because it influences how the rivet expands and secures the materials effectively during the installation process.

Having the correct body diameter ensures that the rivet fits snugly in the intended application, providing adequate strength and stability. Proper grip sizing is equally important because if the rivet is too long for the grip thickness, it may not properly expand or secure the materials; conversely, if it's too short, it may not hold at all.

In contrast, while head diameter and length are important aspects in certain applications, they are not the primary dimensions used for sizing blind rivets. These components can affect the fit and aesthetic of the finished assembly, but they don’t determine the suitability of the rivet for particular materials and thicknesses like body diameter and grip do.
