....using them with springbars depends on which springbar as there are many styles and not all are compatible with the tubes...with some that don't have a single or double circumference ring straps are harder to remove once in place with the tubes because the tube is very close to the inside of the lug....I only use them with watches that have lug screws as it does add tensile strength and fills any void left from some after market strapmakers who like to leave excess leather or larger lug holes in their straps.
He said "tensile"
Tensile strength (σUTS or SU ) is indicated by the maxima of a stress-strain curve and, in general, indicates when necking will occur. As it is an intensive property, its value does not depend on the size of the test specimen. It is, however, dependent on the preparation of the specimen and the temperature of the test environment and material. The standard way to measure tensile strength is to use a small bar with uniform width (apart from at the edges where the thickness increases) and to 'pull' at each end until the bar fails. In the process, other mechanical properties may be obtained. Other testing methods also exist, such as the plane strain compression test.
Tensile strength, along with elastic modulus and corrosion resistance, is an important parameter of engineering materials used in structures and mechanical devices. It is specified for materials such as alloys, composite materials, ceramics, plastics and wood.
