Squared Bosshead
Squared Bosshead (Product Code: SLE/BH/13) is an 18/10 stainless steel connector used to clamp two rods square to each other in rod frameworks and fixed laboratory rigs. It is catalogued at d/Ø 12-13 x 12-13 with a 90° angle, tightened with hexagon socket screws, and can be combined with a connection bar (d = 12 mm x 50 mm) to adjust the angle from 0-360°. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, produces it at its own factory in Ambala, India.

What Is the Squared Bosshead Used For?
A squared bosshead is the connector of choice when a rod framework must stay exactly square: a grid of rods above a bench holding sensors or electrodes, a fixed support for a column or condenser that should not drift between sessions, or a test rig in an instrument or process lab. Hexagon socket screws sit neatly and are tightened with a hex key, so the joint is not loosened casually by students passing the bench. That makes it a tidy, tamper-resistant version of the familiar lab stand clamp boss head for shared rooms.
For angled work, add the connection bar: it lets the joint be set anywhere in the 0-360° range while keeping stainless parts throughout. Keep a correctly sized hex key with the rig, tighten screws evenly, and clean off chemical residues so the stainless steel keeps its finish.
What to Specify When Ordering
- Which listing you need: d/Ø 12-13 x 12-13 at 90°, or the d/Ø 12 entry.
- Whether the connection bar (d = 12 mm x 50 mm) is required for angle adjustment.
- Rod diameters in your framework.
- Quantity of bossheads per rig.

Frequently Asked Questions
What rods does the Squared Bosshead take?
The Squared Bosshead is catalogued at d/Ø 12-13 x 12-13, meaning both clamping sides are listed for the 12-13 range. If your rod sits at the edge of that range, confirm the size with ScienceLab via the contact page.
Can the Squared Bosshead hold rods at angles other than 90°?
On its own the Squared Bosshead holds rods at 90°. Combined with a connection bar (d = 12 mm x 50 mm), the angle can be adjusted from 0-360° while the framework stays in stainless steel.
Is the connection bar included with the Squared Bosshead?
The connection bar is presented as a combination option for the Squared Bosshead rather than a standard part. Tell ScienceLab if you need it, and your quotation will list exactly which items are supplied.
What tool is needed to tighten the Squared Bosshead?
The Squared Bosshead uses hexagon socket screws, so it is tightened with a hex (Allen) key. This keeps the joint neat and makes it harder for a fixed rig to be loosened by accident.
What is the second Squared Bosshead listing with d/Ø 12?
The catalogue shows a second 18/10 stainless steel Squared Bosshead entry at d/Ø 12 with no fixed angle stated. Ask ScienceLab which entry suits your setup, and the difference will be explained in the quotation.
Who manufactures the Squared Bosshead?
The Squared Bosshead is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as OEM at its licensed factory in the HSIIDC Industrial Area, Saha, Ambala, and is supplied factory-direct to laboratories, dealers and importers.
What details speed up a quotation for the Squared Bosshead?
For the Squared Bosshead, give code SLE/BH/13, quantities, rod size, whether the connection bar is needed and the delivery destination. ScienceLab supplies India and international markets from Ambala.
