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

  1. 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.
  2. 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.
  3. Use 079810 only where compatible aluminum welding and the underlying structure are appropriate. Check the manufacturer's installation guidance.
  4. 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.
  5. 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.
