IMSCREWS 5/16"-18 x 7/8" Heavy-Duty 304 Stainless Steel Carriage Bolts (25 PCS)

Reliable Support for Compact Structural Connections
The IMSCREWS 5/16" x 7/8" carriage bolt is designed for projects requiring high shear resistance in a compact size. With a robust 5/16-inch diameter, these bolts are well-suited for high-load joints where a longer bolt is not feasible, such as mounting heavy-duty steel brackets or joining thin timber sections. Built for stability, they offer the durability necessary for long-term use in outdoor furniture, equipment mounts, and garden structures.

High Durability and Safety-Focused Design
Forged from 18-8 (304) stainless steel, these fasteners are highly resistant to corrosion in outdoor environments and are compatible with pressure-treated lumber. The smooth round head offers a clean appearance that reduces snagging hazards, making them an ideal choice for benches, play sets, and railings. The integrated square neck prevents the bolt from spinning, allowing for easy, one-sided installation with a single wrench.
