The phrase "Vis Canon Pour Hublot" directly translates from French as "Cannon Bolt for Porthole." This seemingly simple term encompasses a world of specialized marine-grade fasteners crucial for the secure and reliable installation of portholes, often found on boats, yachts, and other marine applications. These bolts, typically made from high-quality stainless steel, are designed to withstand the harsh marine environment, resisting corrosion and maintaining structural integrity even under considerable stress. This article will delve deep into the intricacies of "Vis Canon Pour Hublot," exploring their various types, applications, specifications, and the importance of selecting the correct fastener for the job.
Understanding the Components: More Than Just a Bolt
The term "Vis Canon Pour Hublot" isn't just referring to a single bolt; it encompasses a system of components designed to work together to create a secure and watertight seal around a porthole. This system typically includes:
* The Cannon Bolt (Vis Canon): This is the main cylindrical bolt, often featuring a threaded shaft. Its design is crucial for creating a strong connection. The diameter and length are critical parameters, directly influencing the strength and suitability of the fastener. The information provided indicates diameters of 4/10mm and 4/16mm, suggesting a variation in the overall size of the bolt. These dimensions likely refer to the nominal diameter and the length of the bolt's threaded portion.
* The Female Receiver (Ecrou femelle de reliure): This is the corresponding female component that receives the cannon bolt. It's often embedded within the porthole frame or the surrounding structure. The female receiver ensures a secure and tight connection with the cannon bolt. The material, typically marine-grade stainless steel (INOX A4), is vital for corrosion resistance.
* The Washers and Gaskets (implied): While not explicitly mentioned in the provided text, washers and gaskets are essential components in a proper porthole installation. Washers distribute the load evenly across the surface, preventing damage to the materials. Gaskets provide a watertight seal, preventing water ingress. The choice of gasket material (e.g., neoprene, EPDM) is crucial for its resilience and compatibility with the marine environment.
Types and Specifications of Vis Canon Pour Hublot:
The provided text highlights several variations of "Vis Canon Pour Hublot," emphasizing the importance of selecting the appropriate fastener for the specific application. Let's break down the key categories:
* Vis canon ø6mm femelle en inox pour hublot bateau: This refers to a female 6mm diameter stainless steel cannon bolt specifically designed for boat portholes. The "femelle" indicates that this is the female receiver, the component embedded in the porthole frame. The stainless steel construction is crucial for corrosion resistance in the harsh marine environment.
* Vis canon inox filetage M4 pour hublots et capots de: This category specifies a stainless steel cannon bolt with an M4 thread. The M4 designation refers to the metric thread size, indicating a relatively small bolt suitable for smaller portholes or access panels. The inclusion of "capots de" suggests its applicability beyond portholes to other deck fittings.
* Les Vis de hublot en inox marine A4: This broadly refers to stainless steel porthole screws, encompassing various types and sizes, all constructed from marine-grade A4 stainless steel. The A4 designation is crucial, indicating high corrosion resistance suitable for marine applications.
