M12 316 Socket Drive D Shackle — Marine-Grade D Shackle by Anzor

The M12 316 Socket Drive D Shackle from Anzor is a compact, marine-grade fastener designed to tackle demanding rigging, lifting, and securing tasks with confidence. Crafted from 316 stainless steel, it delivers exceptional corrosion resistance in saltwater, chemical environments, and outdoor settings, making it a reliable choice for boats, docks, workshops, and light industrial setups.

The distinctive D-shaped body ensures efficient load transfer while maintaining a clean, space-saving profile for tight installations. The M12 size provides a compact footprint without sacrificing strength, perfect for vessels, trailers, and precision rigging where space is at a premium.

Equipped with a socket-drive pin, this shackle supports tool-assisted tightening for secure pin engagement and reduced loosening from vibration in dynamic applications. The tool-friendly design promotes a reliable connection even under frequent loading and unloading, giving you peace of mind on deck, in the shop, or on the job site.

What makes this D Shackle stand out is the combination of marine-grade stainless steel and a secure, tool-friendly pin that stays engaged in challenging conditions. Its corrosion resistance extends service life in environments where coatings alone aren’t enough, helping to lower maintenance needs and replacement costs over time.

Ideal use cases include marine rigging for sailboats, dinghies, and keelboats; securing loads and anchor lines dockside or offshore; lifting small to medium gear in workshops or construction sites; and providing temporary fastening points for outdoor events, staging, or temporary fixtures in outdoor environments.

Practical tips: Inspect the pin and body for wear, corrosion, or deformation before use. Use compatible hardware and ensure the pin is fully seated and tightened with the appropriate tool for a secure fit. Rinse with fresh water after exposure to salt spray, then dry to prevent streaking. Store in a dry, organized area away from corrosive chemicals when not in use.
