The stainless steel finish provides superior rust prevention, a critical factor for outdoor applications in India's humid environment. The self-locking square neck simplifies installation, saving you time and effort. Unlike generic fasteners, these are sourced from authorized US retailers, ensuring consistent quality and performance for your construction and repair needs. **Ideal for Outdoor Woodwork, Less Ideal for Fine Metalwork** — These bolts are perfect for wooden decks, fences, playground equipment, and timber framing where a secure, rust-resistant connection is needed. They are best suited for wood-to-wood or wood-to-metal applications. If you require precise, high-tolerance metal-to-metal connections with specific thread classes or need bolts for applications requiring extreme tensile strength beyond Grade 2, consider specialized machine bolts or high-tensile bolts. ## How to use 1. Measure the combined thickness of the materials you are joining. Choose a carriage bolt length that will pass through both materials and allow for the nut and washer (if used) with a few threads exposed. — Select Bolt Length 2. Drill a hole in the first material and a square hole (or slightly larger than the bolt's square neck) in the second material where the bolt head will sit. The square hole prevents the bolt from spinning. — Prepare the Hole 3. Insert the bolt through the aligned holes. Place a washer (optional) and nut onto the threaded end. Tighten the nut securely. The square neck will engage and prevent the bolt head from turning. — Insert and Tighten ## Product details | Field | Value | |---|---| | Primary Use | Fastening wood to wood or wood to metal | | Application Environment | Outdoor, humid, coastal | | Installation | Self-locking square neck prevents spinning; no driving tool needed | | Finish Type | Semi-flush dome head | | Brand | Hillman | | Material | Stainless Steel | | Finish | Zinc | | Head Style | Round Carriage | | Diameter | 1/4 inch (6.35 mm) | | Length | 1-1/2 inch (38.1 mm) | | Thread Size | 1/4"-14 UNC | | Thread Coverage | Partially Threaded | | Head Underside | Square, Self-Locking | | Pack Quantity | 50 pieces | | Hardness Grade | Grade 2 (Manufacturer Declared) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### What is a carriage bolt used for? A carriage bolt has a smooth domed head and a square neck under the head that locks into wood or a squared hole, preventing the bolt from turning while you tighten the nut. It is commonly used for wood-to-wood and wood-to-metal joints such as decking, fencing, playground equipment, and timber framing. ### How do I choose the right size carriage bolt? Measure the combined thickness of the materials being joined, then add room for the washer and nut. Choose a diameter suited to the load (thicker for structural joints) and a length that leaves a few threads exposed past the nut. Match the finish to the environment — stainless or galvanized for outdoor use. ### Are these Hillman carriage bolts rust-proof for Indian conditions? Yes, these bolts are made of stainless steel, which provides superior rust prevention. This makes them highly suitable for outdoor applications in India's humid climate and monsoon seasons, offering better corrosion resistance than standard zinc-plated fasteners. ### Can I use these bolts for metal-to-metal connections? While primarily designed for wood-to-wood or wood-to-metal, these bolts can be used for metal-to-metal connections if the receiving material has a square hole to accommodate the bolt's neck. For purely metal-to-metal applications requiring specific thread engagement or higher shear strength, consider machine bolts. ### How do I buy original Hillman carriage bolts in India? CrowCrowCrow imports these Hillman carriage bolts directly from authorized US retailers. They are factory-sealed and shipped with all customs duties and GST included, arriving via ExpressBox tracked delivery to your pincode. ### What is the thread type and pitch for these bolts? These 1/4-inch diameter carriage bolts feature a UNC (Unified National Coarse) thread with a pitch of 14 threads per inch (1/4"-14 UNC). They are right-hand threaded. ### Do I need a washer with these carriage bolts? The flat head of these carriage bolts is designed to provide a semi-flush finish and often eliminates the need for a separate washer, especially when fastening into wood. However, for certain applications or to distribute load more evenly, a washer can still be used. ## Compliance No product-specific compliance warnings identified.
