Description
Hook bosshead, nickel-plated steel, d=13 mm is a laboratory clamp fitting for secure rod and apparatus mounting on stands and frames. Made from steel with a nickel coating, this 90° hook bosshead accepts rods of 13 mm diameter and uses an M8 thread for firm fastening. The greatest clamping span is 13 mm, and the unit weighs 104,0 g, giving a compact yet solid connection point for scaffolding used in chemical, analytical and teaching laboratories. The nickel-plated finish supports corrosion resistance in everyday bench environments while keeping a clean professional appearance. Offered as a single piece from manufacturer Bochem, the bosshead fits standard laboratory rod systems where angled hook-style retention is needed. Its defined geometry helps position glassware holders, clamps and accessories along vertical or horizontal rods with stable alignment. Suitable for assembling retort stands, cross-connections and modular support structures, it delivers straightforward mechanical reliability for research, quality-control and educational setups that demand durable, easy-to-handle fittings without complex adjustment hardware.

Questions about Hook-bosshead steel, nickel plated, d=13mm
What is this article?
Hook-bosshead steel, nickel plated, d=13mm 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.
