A plurality of hidden clips can be included with a strip of clips and separated by a frangible section or tab located between adjacent clips. Each strip can be provided with a hand grip portion removably attached to a proximal-most hidden clip in the strip of clips. An aperture defined in each hidden clip can include an offset cylindrical section that causes a fastener to pivot from a vertical alignment when the fastener is driven into a joist.
