Picture frame turn buttons hold a backing panel against a frame and pivot aside when the panel needs to be released. They are not wall-hanging hooks. To choose them, compare the backing position with the frame, allow room for the tab to rotate and check screw clearance. The black steel buttons discussed here are 23 mm long, with a 4 mm offset and matching 8 mm screws; those measurements do not establish a universal frame fit.
The raised bend separates the eyelet end from the rounded tab. The listed 4 mm offset describes that fastener shape; it is not a promise that every 4 mm backing panel will fit. A panel's thickness and its height relative to the frame back are different measurements. A recessed panel, a flush panel and one projecting beyond the frame can present different contact positions even when the panels have the same thickness.
Compare the intended screw seat with the surface the tab needs to retain. The tab should reach that surface in the intended arrangement without forcing or bending the hardware to make it fit. This listing supplies one specification, not a selection of offset heights. If the frame construction or backing position is unclear, ask for compatible hardware advice before choosing rather than treating any turn button as interchangeable.
The 23 mm dimension is the button's overall length, including the eyelet end. It is not a stated measurement from the screw center to the tip. Likewise, the 6.3 mm tab width does not tell you how much overlap your backing will receive. Check the actual shape against the proposed screw position, the panel edge and nearby frame details.
Leave enough space for the tab to move between its retaining and released positions. A corner, another fitting or the edge of a stand can obstruct that path. Do not choose by overall length alone, and do not infer a fixed number of buttons per frame from the 50-set box. The layout depends on the frame and backing arrangement; an existing fitting pattern is not proof of compatibility with a different fastener.
The matching screws are listed as 8 mm long with cross-heads. Compare their intended path with the wooden frame's thickness and the actual fixing position before fitting. Avoid assuming that a screw supplied with hardware is safe for every frame edge. A thin edge, an awkward angle or a position near the front can change the risk of penetrating or damaging the frame.
The 3.2 mm eyelet hole is a button measurement, not a supplied screw-thread diameter, pilot-hole size or driver-bit specification. Those installation details are not established here. The basic arrangement is a screw through the eyelet into the wooden frame, with the tab pivoted over the panel. For a delicate frame, uncertain material or valuable artwork, seek a framer's advice rather than improvising drilling depths or forcing a fitting.
Choose this format when your wooden frame and backing arrangement suit a rotating offset tab. Do not assume it is the right hardware for an acrylic display, a metal extrusion or a frame that uses a different retention system. Wall-hanging hardware is a separate decision: these tabs retain the backing and have no listed hanging-load rating.
One box contains 50 black steel buttons and 50 matching screws, and the minimum order is one box. That is a supply quantity, not a recommendation to use 50 buttons on one frame. The frame and backing panel are not included. Check the current product photographs and measurements before buying; this guide does not report a hands-on fit test, an archival assessment or a load test.
Separate the listed dimensions from the measurements you still need on your own frame.
| Check | Listed detail | What to verify |
|---|---|---|
| Shape and material | Glossy black steel; eyelet, raised bend and rounded tab | The intended frame and backing arrangement |
| Length and width | 23 mm overall length; 6.3 mm tab width | Effective reach from the screw position and room to rotate |
| Eyelet and offset | 3.2 mm hole; 4 mm offset | Do not read these as screw gauge or guaranteed panel thickness |
| Matching screws | 8 mm long, cross-head | Frame thickness and the intended fixing path |
| Box contents | 50 buttons + 50 screws; minimum one box | Frame and backing are excluded; layout is a separate decision |
Use the product page for the current hardware photographs and specifications. A display-format comparison can help distinguish the frame you need, but it is not a compatibility list for these buttons.
No. They retain a backing panel and rotate aside to release it. Wall-hanging fittings are separate, and no hanging-load rating is stated for these buttons.
No. The offset describes the button shape. Compare the screw seat and backing surface in the actual frame; panel thickness alone does not establish their relative positions.
No universal fit is established. Check the wooden frame's thickness and intended fixing path. Screw-thread diameter, pilot-hole size and a safe drilling depth are not provided here.
Do not assume compatibility. The described fitting is a screw through the eyelet into a wooden frame. An acrylic frame may use a different system; check its construction and instructions.
One box contains 50 glossy black steel turn buttons and 50 matching cross-head screws. The minimum order is one box. A frame and backing panel are not included.
