Specifications

What Is the Chrome-Plated Cast Iron Bosshead Used For?

Malleable iron is cast iron that has been heat-treated to make it tougher and less brittle, so a bosshead made from it tolerates repeated tightening and the occasional knock without cracking. The chromium plating protects the iron and gives a bright surface that is easy to wipe. On the bench, the bosshead holds clamps, rings and cross rods at right angles to an upright rod: supporting a separating funnel, fixing a condenser during distillation, or joining rods into a frame for a physics demonstration.

The three d/Ø sizes let you match the bosshead to the rods you already use, with the larger versions intended for thicker rods and heavier frameworks such as those in lab equipment for technical institutes. Fit the thumb screw where users adjust heights often, or the safety screw where the screw should stay with the bosshead. Tighten firmly, test the joint by hand before hanging glassware, and dry the plating after it is splashed.

What to Specify When Ordering

• Size: d/Ø 16,5, 20,0 or 36,0 (all thread 8, 90° angle).
• Screw type: heart-type safety screw or thumb screw.
• The diameter of the rods you use, so we can match the right size (the listing states no unit).
• Quantity for each size, if your laboratory runs rods of different thicknesses.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM for this chrome-plated bosshead and makes it at the company's own licensed factory at Saha, Ambala, Haryana, India. It is supplied straight from there to school and college laboratories, technical institutes, distributors and importers in India and international markets, without a trading middleman.

Because all three sizes come from the same maker, a mixed order is quoted and packed together, and repeat supplies or spare screws can be requested from the manufacturer directly. Details about the company are on the profile page.

Frequently Asked Questions

Which d/Ø size of the Bosshead Malleable Cast Iron Chromium Plated do I need?
Choose the size that matches your rods: the Bosshead Malleable Cast Iron Chromium Plated is listed at d/Ø 16,5, 20,0 and 36,0, written with decimal commas. Units are not stated, so tell us your rod diameter and we will confirm the correct version.

What is malleable (tempered) cast iron?
It is cast iron that has been heat-treated for toughness, so the Bosshead Malleable Cast Iron Chromium Plated is less likely to crack under repeated tightening than ordinary cast iron, while its chromium plating adds a corrosion-resistant, easy-to-wipe surface.

Which screws are available for this bosshead?
The Bosshead Malleable Cast Iron Chromium Plated is listed with a heart-type safety screw, intended to stay captive in the bosshead, or a thumb screw for quick finger adjustment. Please state your choice when you send an enquiry.

Do all sizes share the same thread and angle?
Yes. All three listed versions of the Bosshead Malleable Cast Iron Chromium Plated, d/Ø 16,5, 20,0 and 36,0, have thread 8 and a fixed 90° angle, so only the size and screw type need to be chosen.
