1/4″ x 2-5/16″ Shoulder Lag Eye Bolt – Stainless Steel Type 316

This shoulder lag eye bolt is designed for secure anchoring and lifting in wood applications where through-bolting is not practical. Featuring a lag thread for strong grip and a reinforced shoulder, it supports both vertical and angular loads when properly installed. Constructed from Type 316 stainless steel, it delivers excellent resistance to corrosion in marine and high-moisture environments.

Please Note: Loading at an angle will significantly reduce a bolt’s rated capacity; a 45 degree angle reduces it to just 1/4 of the stated rating. Never load at an angle greater than 45 degrees from the bolt center line.

Stainless Steel Shoulder Lag Eye Bolt Built for Angular Load Strength

When you need a dependable anchor point in thick wood without the need for full pass-through hardware, this shoulder lag eye bolt gets the job done. The shoulder design reinforces the eye and shank, helping resist bending under load, while the lag threads provide strong holding power. Ideal for rigging, marine, and structural tie-down applications where durability matters.
