Types of Fasteners for Marine Applications
Numerous applications call for a wide range of marine components and fasteners. These parts are intended to ensure a quality product for manufacturers of boats, rigs, docks, and commercial and naval ships.
Metal Lock Nuts
Metal lock nuts are used to secure bearings to a shaft and are intended to prevent component loosening due to vibration and rotation. These fasteners are essential for marine transportation, like fishing boats, ships, ferries, towboats, and tugboats.
Standard metal lock nuts include flange, keps, stover, and two-way reversible lock nuts.
Carriage bolts connect wood to wood, metal to metal, and wood to metal. Their unique shape allows the bolt to self-lock when placed through a square hole, which is especially useful when dealing with metal. They are commonly used in producing boat and ship components like helm and fishing seats, folding seats, pontoon boat seats, lounge seats, and other table and seat hardware.
The most common carriage bolts include roundhead and rib-necked bolts, flathead and square-necked bolts, and fin-necked bolts.
Socket Head Fasteners
Socket head fasteners are commonly used in marine applications with insufficient room to maneuver wrenches or sockets. These include die fixturing, machining, and clamping boat and ship parts located in cramped corners.
Some commonly used socket head fasteners include socket head cap screws, flat head socket caps, button head socket caps, ferry cap screws, and low head socket cap screws.
Lag bolts or lag screws are among the most durable fasteners. These robust fasteners are typically used in the marine industry to connect heavy lumber or other heavy materials bearing a heavy load.
The most common materials for lag bolts are zinc, stainless steel, silicone bronze, and galvanized steel.
Machine bolts are used to fasten two material pieces. They are similar to hex bolts but do not have a grooved point and are not designed with a washer-bearing surface on the underside of the head. They are commonly available in both hex and square head configurations.
Flat washers, also known as plain washers, are used in various marine applications to distribute the fastener’s load while minimizing friction and heat during the tightening process. They are also used as spacers, common in domestic and industrial applications.
Several types of flat washers include fender washers, hardened washers, metric flat washers, inch flat washers, and stainless steel flat washers.
