Professional Applications & Engineering Value

This M8 x 1.25mm nylon insert flange lock nut delivers exceptional engineering value in applications where vibration-induced loosening poses significant reliability concerns. The combination of 18-8 stainless steel construction and integrated nylon insert locking mechanism creates a durable fastening solution that withstands harsh operating conditions while preventing corrosion. The 17.9mm flange diameter provides superior bearing surface distribution, reducing stress concentrations and surface damage. Particularly valuable in industrial machinery, automotive assemblies, and electrical enclosures, this DIN 6926 compliant fastener maintains clamping force through thermal cycling and mechanical vibration, eliminating the need for secondary locking devices and reducing assembly time while ensuring long-term joint integrity.

Specification Summary & Compliance

Manufactured to DIN 6926 specifications with Class 6H thread fit precision and metric coarse threading (M8 x 1.25mm). Features right-hand thread direction with external hex drive (13mm width) and integrated flange (17.9mm diameter, 1.2mm thickness). The nylon insert provides reliable locking performance with maximum temperature rating of 250°F. Fully compliant with RoHS 3 (2015/863/EU) environmental standards for industrial applications requiring regulated material composition.
