Buttress threads or saw threads
Buttress threads are also known as saw threads or the breech-lock thread from. Our product range of threaded spindles includes single-start and multi-start ISO-metric buttress threads according to German standards DIN 513, DIN 20401, DIN 2781 and DIN 6063 or any other international standard.
Since we can manufacture our tools by our own in-house production, we have the ability to produce any special design according to your mechanical drawing or sample.
Application of buttress threads
Due to their asymmetrical shape buttress threads are suitable for resisting extremely high single direction axial loads.
Buttress threads are often used as drive thread in hydraulic presses like spindle presses, in lifting systems and lifting tools or for chucks in turning and milling centres.
