Glass Door Handle Hole Size: 12mm for M6, 16mm for M8

Updated 2026-11-05 · RAYEN 雷茵

We list 57 glass door handles. Most of them carry a printed fixing screw and hole size, and the two tables below give all of them. A hole size matters more on glass than anywhere else, because this is the one door you cannot correct on site.

What hole size does a glass door handle need?

• M6 screw: φ12mm in glass, φ8mm in a flush door.
• M8 screw: φ16mm in glass, φ10mm in a timber door.

Those two pairs hold on every model below. There is no third size in the glass handle range. The hole goes through the glass at each foot, so the number of holes equals the number of feet.

In this table the Fixing hole column is the hole in the glass.

Why can't you go by the model number?

The G range and the T range share many numbers, and the screw does not always follow. Compare these pairs.

• G1170 is M8, so φ16mm in glass. T1170 is M6, so φ12mm.
• G4227 is M8. T4227 is M6.
• G2888 is M6. T2888 is M8.
• G7110 is M6. T7110 is M8.

Length does not settle it either. G1169 comes as short as 300mm and is M8. G1195 is available up to 2400mm and is M6. Read the figure for the exact model, every time. A 4mm mistake in the diameter means a new sheet of glass.

Why must the holes be drilled before toughening?

Toughened glass cannot be cut or drilled afterwards. Try it and the sheet breaks. So the glass processor drills first and toughens second, and your hole sizes and positions have to reach them before the order goes into production. That makes the handle the first item to confirm on a glass door, not the last.

How do you set the hole positions?

The spacing between holes is the centre distance P. A worked example:

• G1105: 700mm long, P=640mm, Ø22mm bar, M6. Two holes of φ12mm, 640mm apart, centre to centre.
• G1169 in its 450mm length: P=425mm, M8. Two holes of φ16mm, 425mm apart.
• G1252 in its 1422mm length: P=700+700mm, M6. Three holes of φ12mm, with 700mm between each.
• G1111 in its 2000mm length: P=700+500+700mm, M6. Four holes of φ12mm.

Give the processor a drawing with the positions measured from one edge of the sheet. Do not send a handle photo and a verbal size.

What should you check with the glass processor?

The handle sets the diameter and the spacing. The glass thickness and the distance from the hole to the edge belong to your glass specification, so confirm both with the processor against our drawing. Tell us the glass thickness on the order too, so the fittings in the pack suit the door.

Which models need confirming first?

These long and special models need the hole confirmed on the drawing: G1110, G1189, G1211, G1212, G1240, G1271, G1660, G90 and G999. Do not borrow a figure from a similar model. Ask us for the drawing before you release the glass. G1110 looks like G1111 and shares its 2000mm centres, and that is still no reason to assume its hole.

What to write on your order

One line per handle: model, overall length, P, screw size, hole size in the glass, glass thickness, finish, and quantity of pairs. For example: G1105, 700mm long, P=640mm, M6, φ12mm in glass, Ø22mm, satin stainless. Send the glass drawing along with it and we will check the holes against the handle before anything is cut.
