The pack contains 4 bolts (2-1/16" length each), 4 frame plates, 8 flat washers, 8 lock washers, 8 nuts and 1 wrench — everything required for assembly. Size & fit: Bolts measure approximately 2-1/16" to 4-1/2" and are designed to work with 2" x 2" square beams and shafts.

Please verify the outer diameter of your project and confirm the correct inner diameter before purchase. Materials: Bolts are manufactured from 304 steel, providing resistance to rust, moisture and general corrosion. Applications: This square-bolt set is versatile for industrial and maintenance tasks, automotive uses, garment production and general repairs.

Common installations include pipes, wood structures and sailboat trailers, among other projects. Installation tips: We recommend applying oil to the fasteners during installation for smoother threading. Use the supplied manual wrench to tighten nuts and avoid using high-speed drivers, which can damage the threads.
