Standard ASME B18.3 TABLE 1G
Zylinderschrauben mit Innensechskant und niedrigem Kopf. Dieses Produkt ist zwar eine Präzisions-HV-Schraube, wird aber für leichtere Befestigungsanwendungen empfohlen. Es wird nicht für Anwendungen mit HV Verbindungen, bei denen normalerweise Zylinderschrauben mit Innensechskant verwendet werden sollten. Sie sind für Anwendungen gedacht, bei denen die Kopfhöhe ein Problem darstellt. Aufgrund der geringeren Kopfhöhe und des kleineren Innensechskantes können sie in der Regel nicht so vorgespannt werden wie Standard-Innensechskantschrauben und sollten keinen hohen dynamischen Belastungen ausgesetzt werden.
