Flange Fitting Dimensions & Specs
Exact dimensions for BrassShelf flange fittings — Type D (base flange, no screw holes), Type E (screw-fixed flange) and Type F (wall-mounted 90° connector) — in solid brass and stainless steel. All measurements in inches with millimeters in brackets.
Type D & Type E — Base Flanges
Type D and Type E share the same body. Type E has four countersunk screw holes; Type D has none and is bonded with epoxy where drilling isn't wanted (stone countertops). The pipe stops before the base plate, so each fitting adds a fixed amount to your pipe length.

Type F — Wall-Mounted 90° Connector
Two openings: an end socket for a pipe entering from the front, and a cross bore near the base for a pipe passing through at 90°. Cross pipe centerline is measured from the wall (mounting surface).

Included Hardware & Set Screws
Mounting screws (Type E and F) and all set screws ship in the same material and finish as the fitting and are included in the price. Type D has no screw holes, so it ships with set screws only.
| Pipe / rod | Mounting screws (included) | Short set screw (undrilled pipe) | Long set screw (drilled pipe) | Hex key | Pipe drill size for long set screw |
|---|---|---|---|---|---|
| 15/32" | 4 × Ø5 mm (≈ #10) × 2 3/8" (60 mm) | M5 × 5 mm | M5 × 10 mm | 2.5 mm | 6 mm (≈ 15/64") |
| 5/8" | 4 × Ø5 mm (≈ #10) × 2 3/4" (70 mm) | M5 × 5 mm | M5 × 19 mm | 2.5 mm | 6 mm (≈ 15/64") |
| 3/4" | 4 × Ø6 mm (≈ #12) × 2 3/4" (70 mm) | M6 × 6 mm | M6 × 24 mm | 3 mm | 7 mm (≈ 9/32") |
| 1" | 4 × Ø6 mm (≈ #12) × 2 3/4" (70 mm) | M6 × 6 mm | M6 × 30 mm | 3 mm | 7 mm (≈ 9/32") |
Set Screws: Short vs Long
Every fitting comes with two kinds of set screws, in the same material and finish as the fitting:
- Short set screw — for undrilled pipe. It tightens against the outside of the pipe and clamps it in place. No drilling needed.
- Long set screw — for drilled pipe. The pipe is drilled through one wall only. The screw passes through the fitting and the drilled wall and presses against the opposite inside wall of the pipe, locking the pipe against rotation and pull-out.
We can pre-drill your pipes if you share the hole positions — or you can drill them yourself. We drill one size larger than the screw for tolerance: a 6 mm (≈ 15/64") bit for M5 set screws and a 7 mm (≈ 9/32") bit for M6 set screws. Exact hole positions for a complete unit are shown on the technical drawing you can download from our configurator.

Frequently Asked Questions
What is the base diameter of BrassShelf flanges?
For 15/32" pipe: 2" (50 mm). For 5/8" and 3/4" pipe: 2 3/8" (60 mm). For 1" pipe: 2 3/4" (70 mm). Same for Type D, E and F.
How much length does a Type D or Type E flange add to the pipe?
The pipe stops before the base plate: 3/16" (5 mm) for 15/32", 5/8" and 3/4" pipe; 5/32" (4 mm) for 1" pipe. Example: a 36" pipe with a 5/8" Type E is 36 3/16" overall.
What is the difference between Type D, Type E and Type F?
Type D has no screw holes and is bonded with epoxy on surfaces you don't want to drill. Type E has four countersunk screw holes for screw-fixing. Type F is a wall-mounted connector with an end socket plus a 90° cross bore for a pipe passing through.
Are screws included with the flanges?
Yes. Type E and Type F include four countersunk mounting screws; all types include short and long set screws. Hardware matches the fitting's material and finish and is included in the price.
What size are the set screws?
M5 for 15/32" and 5/8" pipe (short M5 × 5 mm, long M5 × 10 mm or 19 mm); M6 for 3/4" and 1" pipe (short M6 × 6 mm, long M6 × 24 mm or 30 mm).
What drill size do I need for the long set screw?
Drill one wall of the pipe: 6 mm (≈ 15/64") for M5 set screws, 7 mm (≈ 9/32") for M6. We can also pre-drill pipes for you.
Can I get a technical drawing of my unit?
Yes. Design your unit in the BrassShelf configurator and download a dimensioned PDF technical drawing.
