This package contains 100 #6 pan-head screws, each 5/8" long, for attaching compatible picture-framing hardware to wood frames.
The #6 gauge is wider than the #4 gauge. Confirm that it passes through the hardware mounting hole correctly, that the pan head seats against the hardware, and that sufficient sound frame wood surrounds the installation point.
Measure the usable wood thickness at the exact installation location and account for the thickness of the attached hardware. Select a screw that develops useful thread engagement while remaining entirely inside the wood. Frame face width, outside dimensions, or hardware type alone cannot determine a safe screw length.
Critical installation rule: Every screw must enter only sound wood in the frame and must remain completely within that wood. Never drive a screw into or through artwork, canvas, mats, backing, glazing, the open picture area, or the finished face of the moulding.
Choose between #4 and #6 gauges, then compare 3/8", 1/2", and 5/8" lengths. A longer or wider screw is not automatically better: the correct choice must fit the hardware and remain fully contained within the available frame wood.
