Reliable Fastening for Medium-Duty Structural Connections
The IMSCREWS 5/16" x 1" carriage bolt is designed for projects requiring reliable shear resistance in a versatile short size. With a robust 5/16-inch diameter, these bolts are well-suited for high-load joints where longer fasteners are not feasible, such as mounting brackets or joining furniture components. Built for stability, they offer the durability necessary for long-term use in outdoor and indoor structures.

High Durability and Safety-Focused Design
Forged from 18-8 (304) stainless steel, these fasteners are highly resistant to corrosion in humid 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.
