ACMA Top Yoke Nut

The Gilles ACMA Safety Locknut is perfectly engineered from the finest aircraft grade billet aluminium, with an awe-inspiring design. This is then hard anodised to provide a tough, durable and lasting finish. It features Gilles’ patented and innovative easy to use pin lock system. The locking mechanism is activated with a 2.5mm hex key to prevent the ACMA nut from loosening through vibration. This nut: uses a regular 36mm socket; fits a standard M28 x 1mm thread; has a 42mm overall diameter; stands 11mm tall; weighs just 15 grams. The face has a subtle Gilles logo.
