Shipping these was fairly quick. I have no issues with the deliver time. Once received and upon closer inspection I realized many of these fasteners are almost or very close to the same size - let me explain. I focused on the diameters of the fasteners instead of all of it. After receipt I realized these fasteners center diameter changes however, the top of the "T" of the fasteners are all really close to the same diameters. One would think if the shaft diameter get's larger then the top of the fastener would increase - not so. Additionally, these are made from a plastic that is somewhat brittle. I would prefer plastic that would flex and not shatter. Most of these are nearly the same length and as previously stated, nearly the same diameter at the top of the fastener. So other than the diameter of the "bolt" changing, don't expect to use these with a softer material where a wide/large washer is required - Not with this set. I will find a use for them but will look better at the fastener sizes next time. Good Luck!
