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

Substantial Strength for Deep Structural Timber Connections
The IMSCREWS 1/2" x 5" carriage bolt is engineered for heavy-duty structural projects requiring maximum shear resistance and deep penetration. With a robust 1/2-inch diameter and an extended 5-inch length, these bolts are the ideal choice for high-load joints where stability is critical, such as through-bolting multi-layered girders or securing heavy-duty brackets to thick beams. Built for durability, they offer the stability necessary for long-term use in outdoor structures, garden gazebos, and industrial woodworking projects.

High Durability and Safety-Focused Design
Forged from premium 18-8 (304) stainless steel, these fasteners are highly resistant to rust and corrosion in coastal or humid environments. The smooth round head offers a clean appearance that reduces snagging hazards, making them a safe choice for visible railings, play sets, and heavy-duty benches. The integrated square neck prevents the bolt from spinning, allowing for easy, one-sided installation with a single wrench from the nut side.

Specifications:
- Thread Size: 1/2"-13 Coarse (UNC); Length: 5" (Measured from Under Head)
- Material: 304 (18-8) Stainless Steel; Full Thread

Pro-Tips:
1. Use a 1/2" drill bit to ensure a snug, structural fit for the square neck.
2. Pair with stainless steel flat washers and hex nuts on the nut side to distribute structural load and protect wood fibers.

Key Features

• Peak Structural Integrity: The massive 1/2-inch diameter provides the highest level of shear strength and load-bearing capacity, specifically designed for critical joints in heavy timber framing.
• 5-Inch Structural Reach: Engineered for through-bolting thick 6x6 posts or multi-layer support beams, ensuring a permanent, rock-solid connection that lighter fasteners simply cannot provide.
• Marine-Grade 304 Stainless: Forged from premium 18-8 (304) stainless steel, offering superior defense against rust in coastal air, docks, and highly corrosive ACQ pressure-treated lumber.
• No-Spin Square Neck Drive: The precision-cut square shoulder bites deep into the wood, locking the bolt firmly in place for high-torque, one-person installation from the nut side.
• Smooth Safety Head: The low-profile, domed head eliminates sharp protrusions, providing a professional, snag-free finish that is safe for public walkways, playgrounds, and residential decks.
