Abstract
A stress plate for use with a threaded fastener for securing relatively soft insulation to a solid base, such as in a roofing environment, includes a generally planar main body, and a hole on the main body configured for receiving the fastener. The plate is configured so that the hole is angled relative to a vertical axis of the plate for accommodating threads of the fastener so that the fastener is maintained in a generally perpendicular orientation to the main body upon the engagement of the threads of the fastener in the hole. In the preferred embodiment, the threads of the fastener have a helix angle, and the hole, which is formed in a conical depression in the plate, is angled at the same angle as the threads of the fastener.
