IMSCREWS 3/8"-16 x 2-3/4" Heavy-Duty 304 Stainless Steel Carriage Bolts (20 PCS)

Substantial Strength for Heavy Structural and Marine Connections
The IMSCREWS 3/8" x 2-3/4" carriage bolt is engineered for structural projects requiring significant load-bearing capacity and professional durability. With a robust 3/8-inch diameter and a precise 2.75-inch length, these bolts are the ideal choice for securing industrial brackets, dock hardware, and heavy timber-to-metal connections. The length is perfectly suited for passing through 1.5-inch actual thickness lumber while leaving sufficient thread for heavy-duty washers and nuts to ensure a snug, permanent connection. Built for longevity, they offer the structural stability required for outdoor pergolas, heavy fencing, and commercial-grade timber framing.

Superior Durability and Safety-Focused Design
Forged from premium 18-8 (304) stainless steel, these fasteners offer superior resistance to rust and corrosion in coastal or humid environments. The smooth round head creates a clean, tamper-resistant look that reduces snagging hazards, making them a safe choice for high-traffic areas like boardwalks, playground sets, and residential decks. The integrated square neck locks the bolt into place during installation, preventing spinning and allowing for easy, one-sided tightening from the nut side with a single wrench.

Specifications:
Thread Size: 3/8"-16 Coarse (UNC); Length: 2-3/4" (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 304 SS flat washers and hex nuts to distribute heavy structural loads and protect wood fibers.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $21 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for IMSCREWS products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
