Stainless Steel Bow Eye U Bolt – AISI 316 is a strong, practical mounting fitting designed to create a secure attachment point on boats, marine structures, and suitable trailer assemblies. Its rounded U-shaped eye provides a convenient connection point for compatible ropes, straps, hooks, cables, and other fastening hardware. The two threaded legs allow the bow eye to pass through a suitable mounting surface and be secured from the opposite side using the supplied plate and nuts.

Manufactured from AISI 316 stainless steel, this marine bow eye offers good resistance to corrosion in wet, humid, and saltwater-exposed environments. AISI 316 stainless steel is commonly selected for marine hardware because it is suitable for demanding conditions where ordinary metal components may corrode more quickly. Its polished metal finish also provides a clean appearance that complements other stainless steel deck fittings and boat hardware.

This model has a nominal diameter and overall length of 1/2″ x 5-1/4″ (L), with a 3-1/2″ thread length for installation through an appropriately prepared mounting surface. The extended threaded legs provide adjustment space for positioning the plate and nuts according to the thickness and construction of the mounting area. The internal eye opening is approximately 37.4 mm, offering space for compatible connecting hardware. Buyers should verify all mounting dimensions, installation clearance, and connection requirements before ordering.

Unlike a general-purpose U bolt used mainly to clamp pipes or tubes, this stainless steel U bolt is formed with a rounded exposed eye intended to function as an attachment point. It can be installed as a boat bow fitting, tie-down connection, securing point, or general marine attachment eye where its dimensions and intended use are suitable. The included backing plate helps distribute the clamping force across the installation area, while the nuts secure the fitting in position.

Correct installation is important for dependable use. The Stainless Steel Bow Eye U Bolt – AISI 316 should be fitted through correctly spaced mounting holes on a structurally suitable surface. The mounting area should be inspected to ensure it can support the intended application. Appropriate backing, sealant, or additional reinforcement may be required depending on the hull material, panel construction, mounting position, and exposure to water. Any working-load requirement should be confirmed separately, as no rated load capacity is provided for this product.

The smooth U-shaped design makes this u bolt for boat installations a useful choice for new builds, maintenance work, or replacement of a similarly sized fitting. It may also suit selected boat trailer u bolts applications when used as an attachment eye rather than as an axle or suspension clamp. Matching the existing hole spacing, thread size, overall length, and eye clearance will help ensure proper installation.
