Part # HNT-1018

These lock-nuts secure the factory GM LS windage trays or Improved Racing crankshaft scrapers to the factory main studs.

The nut is a Class 10 flange nut with M8x1.25 threads and meets or exceeds the factory specification lock-nut (GM part # 11609746).

Most LS and Vortec family engines require 10 lock-nuts to secure the windage tray. The F-Body oil pan and Holley 302-2 oil pan use shortened windage trays, requiring 8 lock-nuts.

Sold individually.
