Sea-Dog Boat Bow Eyes, Transom Eye Nuts & Deck Plates
Sea-Dog offers several ways to attach an eye to a boat's bow, transom or other suitable structure. Choosing between a thread-on eye nut, a weld-on aluminum fitting and a stainless bow-eye or deck plate requires matching the original connection—not just choosing a similar-sized loop.
Four ways to add an attachment eye
Threaded transom eye nuts
078106 and 078110 screw onto a bolt or threaded rod. They use different UNC threads, so one cannot be substituted for the other on the same hardware.
Weld-on aluminum bow eye
079810 is cast aluminum and is intended to be welded to a suitable aluminum bow, stern or other structure by a qualified installer.
Bolt-on stainless bow eye
080095 is machined 304 stainless steel with a 5/8-inch coarse-thread connection. It is a different shape and mounting method from the weld-on model.
Surface-mounted stainless plate
088721 is an oblong eye plate in 316 stainless, secured using two suitable 1/4-inch flat-head fasteners, which are not included.
Match the fitting to the existing connection
| MPN | Attachment style | Material | Thread / mounting | Typical position |
|---|---|---|---|---|
| 078106 | Thread-on eye nut | Investment-cast 316 stainless | 1/4-20 UNC thread | Transom securement point |
| 078110 | Thread-on eye nut | Investment-cast 316 stainless | 3/8-16 UNC thread | Transom securement point |
| 079810 | Single weld-on bow eye | Cast 356-T6 aluminum | Weld to compatible aluminum | Bow or stern attachment |
| 080095 | Bolt-on bow eye | Machined 304 stainless | 5/8-in NC threaded legs | Bow tie-down point |
| 088721 | Oblong eye plate | Investment-cast 316 stainless | Two 1/4-in flat-head fasteners | Rigging or tie-down point |
Choose by structure, fastener and purpose
- Identify the mounting location: threaded eye nut on an existing bolt or rod, welded aluminum fitting, bolt-through bow eye or screw-mounted oblong plate.
- Match the thread precisely: 078106 is 1/4-20 UNC and 078110 is 3/8-16 UNC. Verify the installed rod or bolt length and supporting structure.
- Use 079810 only where compatible aluminum welding and the underlying structure are appropriate. Check the manufacturer's installation guidance.
- For 080095, confirm the 5/8-inch coarse threaded legs, transom or bow thickness, backing and finish nuts. For 088721, select appropriate 1/4-inch flat-head fasteners and backing.
- Assess the anticipated forces and select a fully specified, rated assembly where the application requires documented load capacity.
Confirm the complete connection. The eye, bolt or welded attachment and supporting structure must all suit the actual load and installation. Material grade, thread size and appearance do not establish an approved working-load limit or safe use for lifting people or overhead loads.
