Acrylic Holder Sign Screw 17x30 (20 Pieces)

Acrylic Stand‑off Sign Fixings 17×30 mm – Pack of 20 Application Kit

These 17×30 mm acrylic stand‑off fixings are decorative fasteners manufactured to mount acrylic, glass, composite, and wood panels to walls with a clean, professional finish. The wide 17 mm head diameter delivers a firm, balanced appearance on the panel surface, while the 30 mm stand‑off length creates a sensible, well‑proportioned gap — neither too close nor too far — ideal for medium‑size signage. This compact pack of 20 supplies exactly the right quantity for several signs or renovation projects. With the locking concealed‑cap system, the screw head is completely hidden; not a single fixing is visible from outside.

• Secure Hold with Wide 17 mm Head: Creates a broad support footprint; distributes pressure evenly to reduce the risk of cracking or warping, especially on glass and larger panels
• Fully Concealed Fixing: The locking cap completely covers the screw head — no fasteners are visible from the front for a flawless, premium‑quality finish
• Versatile Material Compatibility: Works seamlessly with acrylic, glass, composite, MDF, and wood panels 4–12 mm thick; one stock item serves diverse project requirements
• Delicate Surface Protection: Clear silicone gaskets included with every unit prevent direct metal contact, eliminating scratching and pressure damage to acrylic and glass
• Long‑Lasting Brilliance: Chrome plating resists fading, tarnishing, and dulling indoors — retaining its pristine appearance for years
• Perfectly Sized 20‑Unit Pack: Mounts approximately 5 standard signs using 4 fixings each — the ideal quantity where smaller packs fall short and larger ones create 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 front face over the hole — critical for surface protection especially with 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 — excessive pressure can crack glass and thick acrylic 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
