Glass adaptor D30, SS, satin

The Strofix D30 glass adaptor with M10 fixing is a stainless-steel point fixing used to mount 6–12.76 mm glass panels to flat surfaces in balustrades, façades, and partition systems. Available in AISI 304 or AISI 316 grade with a fixed 10 mm spacer, satin finish, and a cover secured by a visible face screw.

Each adaptor secures the glass through a single Ø14 mm pre-drilled hole and is tightened with an M10 × 50 mm stainless-steel screw — a larger fastener than the M8 used on the standard D30, giving a higher-capacity fixing for heavier or more highly loaded glass panels. The 10 mm spacer (un-threaded) sets a short standoff distance between the wall and the glass, and the Ø30 mm cover is retained by a decorative face screw, producing a distinctive exposed-fixing look rather than the smooth cap of the standard D30. AISI 304 suits interior and standard exterior installations; AISI 316 contains added molybdenum for higher resistance to chlorides and salt air, making it the correct choice for coastal and high-humidity environments.

The satin finish reduces visible fingerprints and micro-scratches compared to polished stainless steel, giving a clean, neutral look suited to commercial railings and architectural glazing.

Use cases:

• Balustrades and railings requiring a heavier-duty M10 point fixing
• Commercial and public-building glass façades with higher load requirements
• Glass partition walls in offices, retail, and hospitality spaces
• Pool fencing and seafront balustrades (AISI 316 recommended)
• Stair side glazing and mezzanine edge protection
• Projects where an exposed decorative fixing screw is preferred over a smooth cap

FAQ:

What glass thickness does this adaptor support?

This D30 variant is suitable for glass panels from 6 mm to 12.76 mm thick, covering standard toughened glass and common laminated glass buildups used in balustrades and partitions.

How does this differ from the standard D30 glass adaptor?

The standard D30 uses an M8 screw with a smooth cover cap. This variant uses a larger M10 × 50 mm screw for a higher-capacity fixing and has a cover retained by a visible face screw rather than a smooth cap. The spacer is a short 10 mm (fixed, un-threaded), and the glass hole remains Ø14 mm. Choose this SKU when a heavier-duty fixing is required or when an exposed cover screw matches the project's visual language.

What size hole must be drilled in the glass?

A minimum Ø14 mm hole is required for the M10 through-screw. The hole must be pre-drilled by the glass supplier before tempering — toughened glass cannot be cut or drilled after heat treatment.

What is the difference between AISI 304 and AISI 316?

AISI 316 contains molybdenum, which provides higher resistance to chlorides and salt air. Specify AISI 316 for coastal, pool, and high-humidity installations. AISI 304 is sufficient for interior use and standard outdoor conditions inland.

Is the spacer height adjustable?

No. This SKU ships with a fixed 10 mm spacer, which sets the standoff distance between the wall and the glass. The spacer cannot be adjusted after installation — choose a different D30 variant if a larger offset or adjustable spacer is required.

Can I install it myself?

Yes, with basic tools: a drill with the correct bit for your wall material, a torque wrench, and pre-drilled glass. A wall anchor rated for the M10 screw must be selected separately to match the substrate. Handle glass panels with two people and follow the glass supplier's recommended torque to avoid cracking.

About glass adaptors

A glass adaptor is a stainless-steel point fixing that attaches a glass panel to a supporting structure through a drilled hole in the glass. It transfers load from the panel to the substrate while keeping visible hardware to a minimum, leaving the glass as the main visual element in balustrades, façades, partitions, canopies, and shower enclosures.

Strofix supplies round glass adaptors from Ø12 mm up to Ø70 mm (including D30, D38, D40, D50, D60 and D70) plus square 38×38 and 40×40 versions, in AISI 201, AISI 304 and AISI 316 stainless steel, with satin, polished or painted finishes and a broad range of spacer heights. The right adaptor depends on glass thickness, wall-to-glass offset, environment and the type of supporting surface.

Glass adaptors are essential components used to securely connect glass panels to supporting structures while maintaining a clean, modern appearance. They are widely applied in glass railings, partitions, façades, canopies, and other architectural systems where both stability and design matter. By creating a reliable fixing point between glass and metal or wall-mounted surfaces, glass adaptors help distribute load evenly and ensure structural safety without compromising transparency.
