Substantial Strength for Compact Structural Connections The IMSCREWS 3/8" x 7/8" carriage bolt is engineered for heavy-duty projects requiring maximum shear resistance in a compact, precision-sized profile. With a robust 3/8-inch diameter and a 0.875-inch length, these bolts are well-suited for joints where stability is critical but clearance is limited, such as mounting thick metal brackets to thin panels or reinforcing structural hardware. Built for durability, they offer the stability necessary for long-term use in residential DIY projects and industrial applications.
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 an ideal choice for visible furniture joints and playground equipment. 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: 3/8"-16 Coarse (UNC); Length: 7/8" (Measured from Under Head) - Material: 304 (18-8) Stainless Steel; Full Thread
Pro-Tips: 1. Use a 3/8" drill bit to ensure a snug, structural fit for the square neck. 2. Pair with stainless steel flat washers and nuts on the nut side to distribute structural load and protect material surfaces.
Key Features
Ideal for Compact Mounting: The 7/8-inch short-reach design is Well-suited for securing heavy-duty brackets, plates, or hinges to timber without excessive bolt protrusion on the reverse side.
Maximum Shear Resistance: With a robust 3/8 diameter, these bolts provide superior load-bearing capacity and shear strength for structural hardware and mechanical assemblies.
Anti-Theft Smooth Head: The rounded dome head features no drive socket, making it impossible to unscrew from the outside, providing a low-profile aesthetic and enhanced security.
Marine-Grade Durability: Forged from premium 18-8 (304) stainless steel, ensuring professional defense against rust in humid outdoor settings and coastal environments.
Self-Seating Square Neck: The integrated square neck bites into wood or locks into square metal holes, allowing for quick, high-torque tightening from the nut side alone.
