Description
Cross double bosshead in aluminium alloy with diameter 16,5 mm and safety screw is a laboratory clamp fitting for secure rod and apparatus mounting. The bosshead provides 180° plus 90° angle orientations and uses an M8 thread for firm attachment on standard laboratory stands and frameworks. A safety screw in 18/10 steel adds retention security during setup and use. With a largest clamping span of 16,5 mm, the fitting suits common rod diameters in chemistry and biology workplaces. This cross double bosshead from manufacturer Bochem is supplied as a single piece and weighs 165,0 g (net weight 0,17 kg), making it a compact, durable component for retort stands, frameworks and multi-rod assemblies. Aluminium-alloy construction keeps mass low while maintaining mechanical strength for everyday laboratory clamping tasks. Suitable for general laboratory apparatus support where a cross-type double bosshead with defined diameter and safety screw is required.

Questions about Bosshead, alu d=16,5mm, Safety screw
What is this article?
Bosshead, alu d=16,5mm, Safety screw is the article on this page. Luminix Health distributes Bochem for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Matériel de laboratoire.
A bosshead grips the rod. A clamp grips the flask or the condenser, usually through two jaws with cork or vinyl faces. Three-finger and two-finger clamps hold different shapes. The jaw opening is the specification.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
