Product Overview
Automatic Locking Pin, Safety Pin, Yacht Accessories, Quick Pin Tongue Lock – Model ZB0601 Series
RICHWITS ZB0601 delivers a marine-grade, precision-engineered quick-release safety pin engineered for rapid securing, automatic locking, and reliable fastening in yacht rigging, deck hardware, and marine accessory applications.
Investment-cast from premium 316 marine stainless steel, then CNC-machined and electropolished for lifetime immunity to saltwater corrosion, UV degradation, and tropical marine environments.
Innovative tongue-lock automatic design: push to insert, spring-loaded detent engages instantly—no tools, no clips, no loose parts; press button to release—essential for sail covers, bimini tops, life rafts, and removable safety rails on yachts and superyachts.
Multiple diameters (6 mm–16 mm) and grip lengths (20 mm–80 mm) accommodate standard marine fittings; single-hand operation delivers secure retention—perfect for dodgers, spray hoods, cockpit tables, or tender davits.
Key Features & Benefits
316 SS Investment-Cast Body – zero welds, zero porosity, zero failure in saltwater immersion; molecular uniformity ensures consistent spring tension and detent engagement.
Automatic Tongue-Lock Mechanism – spring-loaded stainless detent ball locks instantly upon insertion; audible click confirms secure engagement; release button for one-hand operation even in rough seas.
Electropolished Smooth Surface – eliminates crevices where salt deposits accumulate; reduces friction, ensures smooth insertion/removal after years of exposure.
Captive Design – No Loose Parts – integrated spring and button; nothing to drop overboard; lanyard attachment point for additional security.
High-Strength Spring Steel Internals – 17-7PH stainless spring provides consistent 50N detent force; tested 100,000 cycles without fatigue.
Ergonomic Knurled Head – positive grip with wet or gloved hands; low-profile design prevents snagging on sails or lines.
Product Uses
Quick pin for sail covers, dodgers, and spray hoods
Safety pin for bimini tops and cockpit enclosures

Product Advantage
High resilience, unlikely to break – ductile 316 SS withstands shock loading, wave impact, and dynamic vessel motion without brittle fracture.
Excellent processing performance – slip-fit tolerance for standard marine bores; compatible with stainless, aluminum, or composite fittings.
Excellent welding performance – 316L grade compatibility for permanent mounting brackets or custom fabrication without carbide precipitation.
Excellent antioxidant properties – surface not prone to rusting; maintains mirror finish and smooth operation for decades in marine environments.
FAQ
Why does stainless steel rust?
a. When dust containing other metal elements or particles of dissimilar metals accumulate on the surface of stainless steel, in a humid environment, the condensate water between the adherent and the stainless steel forms a micro-battery, triggering an electrochemical reaction and damaging the protective film. This is known as electrochemical corrosion.
b. When organic substances such as vegetable juice, noodle soup, and phlegm adhere to the surface of stainless steel, they form organic acids in the presence of water and oxygen. Over a long period of time, these organic acids will corrode the metal surface.
c. The stainless steel surface adheres to substances containing acids, alkalis and salts (such as splashed alkali water and lime water during wall decoration), causing local corrosion.
d. In polluted air (such as that containing large amounts of sulfides, carbon oxides, and nitrogen oxides), upon encountering condensation water, liquid spots of sulfuric acid, nitric acid, and acetic acid are formed, causing chemical corrosion.
