Fastener Locknut-Flanged 5/8-11

Fastener Locknut-Flanged 5/8-11

This is a high-strength, Grade 8 steel flange locknut with a 5/8-inch diameter and 11 threads per inch. The integrated, serrated flange acts as a built-in washer and bites into the mating surface to resist loosening caused by heavy vibration, which is common on concrete mixer trucks and heavy machinery. This one-piece fastener solution is a critical component for securely mounting various parts and is often needed for general maintenance and repairs where high clamping force and vibration resistance are required.
