The 17x20 sign holder screw used for plexiglass sign applications is offered in a pack of 10 pieces.
Acrylic Stand‑off Sign Fixings 17×20 mm – Pack of 10 Compact‑Clearance Set
These 17×20 mm acrylic stand‑off fixings are decorative fasteners engineered to mount acrylic, glass, composite, and wood panels close to the wall with a neat, stylish appearance. The wide 17 mm head diameter delivers balanced, reliable grip on the panel, while the short 20 mm stand‑off length creates a compact profile — ideal for nameplates viewed up close, narrow spaces, and areas with limited ceiling height. This practical 10‑unit pack supplies exactly the right quantity for one sign, urgent replacements, or sample work. With the locking concealed‑cap system, the screw head disappears completely; not a single trace of the fixing is visible from outside.

Product Advantages
- Compact 20 mm Clearance: More understated than 30 mm and 40 mm versions; maintains balanced proportions especially when viewed close‑up, while still leaving enough gap for airflow and easy cleaning
- Reliable Grip with Wide 17 mm Head: Despite the shorter body, the broad head creates a large contact area; spreads pressure evenly to reduce breakage risk — particularly on glass and thin acrylic
- The locking cap completely covers the screw head; no fasteners are visible from the front for a professional, premium‑quality finish
- Universal Material Compatibility: Works seamlessly with acrylic, glass, composite, MDF, and wood panels 4–12 mm thick — one stock item serves across different projects
- Delicate Surface Protection: Clear silicone gaskets prevent direct metal contact, eliminating scuffing and pressure damage to acrylic and glass
- Long‑Lasting Brilliance: Chrome plating resists fading, tarnishing, and dulling indoors — retaining its pristine appearance for years
- Cost‑Effective 10‑Unit Pack: Perfect for single installations and urgent repairs where larger packs are unnecessary; completes your project without surplus stock
Installation Guidelines
- Drill an 8–10 mm diameter hole in the panel; maintain at least 20 mm clearance from the hole to the edge to minimise breakage risk
- Place the clear protective gasket on the outer face over the hole — critical surface protection especially for acrylic and glass
- Secure each stand‑off body to the wall using suitable wall plugs and screws; select fixings appropriate for concrete, brick, aerated block, or timber substrates
- Slot the panel onto the stand‑offs and twist the decorative cap clockwise to lock it in place; the fixing will be completely hidden
- Do not over‑tighten — controlled pressure is especially important with the shorter body and thinner, more fragile panels
- Check tightness after 2–3 weeks; gradually retighten any connections loosened by thermal movement or vibration
- For outdoor installations exposed to persistent rain, choose stainless‑steel finished versions
Frequently Asked Questions
How much coverage does 10 fixings provide?
A standard sign typically uses 4 fixings; this pack mounts approximately 2 signs. Larger panels will require additional fixing points.
Is the 20 mm version different from other lengths?
Yes — the body is shorter; the panel sits closer to the wall, creating a neater aesthetic for nameplates and signs viewed at close range. Head diameter remains 17 mm across all models.
Are wall screws and plugs included?
No — excluded due to varying wall substrates; please select hardware suited to your installation surface.
Safe to use with glass panels?
Yes — fully protected by the gasket; ensure holes are drilled professionally and edges are smoothed/ground.
