Glass adaptor D60 spherical, with inner thread, SS, satin

The Strofix D60 spherical glass adaptor with inner thread is a stainless-steel point fixing used to mount 8–21.52 mm glass panels to flat surfaces in architectural façades, canopies, and feature glazing, with a threaded spacer that allows fine adjustment of the glass offset during installation. Supplied in AISI 304 with a fixed 22 mm spacer, satin finish, a spherical cover, and an M10 × 45 mm screw.

The Ø60 mm spherical (domed) cover gives the fixing a distinctive rounded profile and allows small angular deviations between the glass and the mounting surface, which is useful in façade and canopy applications where perfect planarity between substrate, spacer, and panel cannot be guaranteed. Each adaptor secures the glass through a single Ø19 mm pre-drilled hole, with an 18 mm inner bushing diameter, and is tightened with an M10 × 45 mm stainless-steel screw that engages the M10 inner thread of the 22 mm spacer. The threaded spacer lets the installer fine-tune the standoff distance on site — listed as "slightly adjustable" — which is useful for aligning multiple panels along a façade or compensating for substrate irregularities. AISI 304 is the standard chromium-nickel stainless steel and provides reliable corrosion resistance for indoor installations and standard protected outdoor environments away from coastal conditions.

The satin finish reduces visible fingerprints and micro-scratches compared to polished stainless steel and suits architectural glazing where a clean, neutral look is required.

Use cases:

• Architectural glass façades and curtain wall point-fixed panels requiring on-site alignment
• Glass canopies, entrance awnings, and porte-cochères with tight alignment tolerances
• Heavy-duty balustrades with thick toughened or laminated glass up to 21.52 mm
• Full-height glass partitions and atrium walls in commercial interiors
• Retail storefront and shopfront glazing on prepared substrates
• Feature glazing where a rounded, domed fixing is part of the design language

FAQ:

What glass thickness does this adaptor support?

This D60 spherical variant is suitable for glass panels from 8 mm to 21.52 mm thick, covering standard toughened glass and thicker structural laminated glass buildups commonly used in façades and heavy-duty balustrades.

What does the "inner thread" enable?

The 22 mm spacer has an M10 internal thread, so the M10 × 45 mm screw engages the spacer directly rather than passing through it. The installer can rotate the fixing to fine-tune the standoff distance on site — listed as "slightly adjustable". This is useful for aligning multiple panels precisely along a run or compensating for small substrate irregularities.

What does "spherical" mean for this adaptor?

The Ø60 mm cover has a rounded, dome-shaped profile rather than a flat disc. The spherical geometry gives the fixing a distinctive visual signature and allows small angular tolerances between the mounting plane and the glass — useful in façade and canopy applications where perfect alignment is hard to guarantee.

What size hole must be drilled in the glass?

A minimum Ø19 mm hole is required. The adaptor uses an 18 mm inner bushing diameter. The hole must be pre-drilled by the glass supplier before tempering — toughened glass cannot be cut or drilled after heat treatment.

What stainless steel grade is used?

This SKU is supplied in AISI 304, the standard chromium-nickel stainless steel. AISI 304 provides reliable corrosion resistance for indoor installations and standard protected outdoor environments. For coastal, pool, or chloride-rich locations, a higher-grade stainless steel such as AISI 316 should be specified.

Can I install it myself?

Yes, with basic tools: a drill with the correct bit for your wall material, a torque wrench, an M10-rated wall anchor matched to the substrate, and pre-drilled glass. Once the wall anchor is set, the threaded spacer can be rotated to fine-tune the standoff before the cover is tightened. Thick laminated glass panels should be handled with two people 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.
