Marine Boat Folding Mast Step. 316 Stainless Steel Folding Mast Step (commonly called a transom step or flip-up pad eye step). It is a specialized piece of marine hardware designed to provide a secure foothold on sailboat masts, transoms, or high vertical surfaces while maintaining a completely low-profile, snag-free design when folded.
Key Features & Design Layout
Material Construction: Heavy-duty, solid-cast 316 marine-grade stainless steel polished to a mirror finish to resist extreme saltwater rust and pitting.
Spring-Loaded Action: Equipped with a built-in heavy-duty stainless steel internal spring plate. This provides a tight, positive snap action that keeps the step locked firmly in the open or closed position, preventing it from rattling in the wind or from engine vibrations.
Non-Slip Grip: Features a textured diamond tread pattern across the stepping surface to ensure secure traction for shoes and boots in wet conditions.
Countersunk Mounting: Designed with two pre-drilled countersunk mounting holes (typically for M6 or 1/4" flat-head fasteners) to ensure the mounting screws sit perfectly flush against the hardware frame.

If you are planning to install or mount these steps, let us know:
What surface material or backing structure are you mounting them to? (aluminum mast, fiberglass transom, trailer frame?)
Do you need assistance verifying the center-to-center hole spacing layout to match an existing set of holes?
Are you looking for a specific weight capacity rating for heavy equipment climbing?
