IMSCREWS 1/2"-13 x 5" Heavy-Duty 304 Stainless Steel Carriage Bolt (1 PC)

Substantial Support for Deep Structural Connections
The IMSCREWS 1/2" x 5" carriage bolt is engineered for heavy-duty projects requiring maximum penetration and reliable structural support. With a robust 1/2-inch diameter and an extended 5-inch length, this bolt is well-suited for high-load joints, such as through-bolting thick timber beams or reinforcing large-scale deck railings. Built for heavy framing, it offers the stability necessary for long-term use in docks, retaining walls, and industrial garden structures.

High Durability and Safety-Focused Design
Forged from 18-8 (304) stainless steel, this fastener is highly resistant to corrosion in outdoor environments and is compatible with pressure-treated lumber. The smooth round head offers a clean appearance that reduces snagging hazards, making it an ideal choice for high-traffic areas like benches, playgrounds, and railings. The integrated square neck prevents rotation, allowing for easy, one-sided installation with a single wrench from the nut side.

Pro-Tips:
1. Ensure the pilot hole is perfectly perpendicular for 5" bolts to avoid alignment issues across multiple timber sections.
2. Pair with a heavy-duty flat washer on the nut side to distribute structural load and protect wood fibers.
