⚙ Quarter-Turn Fastener Systems
Skybolt produces fastener families compatible with industry-standard Camloc®, Dzus®, and Airloc® designs:
- CLoc® Series – Camloc®-style quarter-turn fasteners (most common in general aviation and commercial aerospace)
- DLoc® Series – Dzus®-style spring-loaded fasteners
- ALoc® Series – Airloc®-style fasteners (common on Beechcraft applications)
Most Skybolt quarter-turn fasteners use 300-series stainless steel, avoiding the corrosion susceptibility of A286 or 400-series alloys while maintaining superior strength-to-weight performance.
