Description
BOLA hexagon nuts M 4 PTFE are laboratory fastening elements manufactured from polytetrafluoroethylene for chemically aggressive and metal-free assemblies. Designed similarly to DIN 934 / DIN EN ISO 4032, each nut features an M 4 thread with a 0,7 mm pitch, a 7 mm hexagon and a height of 5,0 mm. The PTFE construction supplies outstanding chemical resistance, low friction and thermal stability, making the nut suitable for apparatus assembly, fixture work and corrosive-media handling in research and industrial laboratories. Supplied as a single piece with a net weight of 0,0002 kg, it supports clean mechanical joints where metallic contamination must be excluded. These BOLA nuts from manufacturer Bohlender pair effectively with matching PTFE screws and fittings in glassware and polymer-based laboratory systems. The non-stick character of the material simplifies cleaning and reduces residue build-up during repeated use, while the standardised hexagon geometry allows reliable tightening with common laboratory tools.

Questions about BOLA Hexagon Nuts, M 4 PTFE
What is this article?
BOLA Hexagon Nuts, M 4 PTFE is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Other lab tools & accessories, inside Tools & accessories, in Matériel de laboratoire.
This shelf is the bench tools that do not belong to a narrower rack: odd holders, small aids, pieces that complete a setup. The useful check is what the tool touches, and whether that contact adds a contaminant.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
